This is from 2016, a lot has happened since then:

- The FDA recognized psilocybin as a breakthrough therapy for treatment-resistant depression: https://www.prnewswire.com/news-releases/compass-pathways-re...

- Some more studies, such as https://pubmed.ncbi.nlm.nih.gov/27909164/

- More widespread use in medical treatment, such as approval in Australia (https://www.bbc.com/news/world-australia-66072427) and limited approval in Switzerland

Very much anecdotal but I can say that psychedelics helped me and several friends a lot with depression. They don't just magically make you feel better - at least not long-term - but they give you the neuroplasticity you need to adjust your internal filters and behaviour. As such, if the purpose is truly healing and recovery, they're best paired with professional therapy, preferably from somebody who's experienced with psychedelic-assisted therapy specifically.

Wonder how Adderall with its fourfold amphetamine recipe can fast-track to market, while psylocibin with all its ancestral approval had not yet been pilled AT ALL. How can a soldier designated pill make it to 60m prescriptions and amazing substantiated illegal use, while psylocibin is still rated as schedule-1 drug alongside heroine, which of course is major offense to possess.

https://en.wikipedia.org/wiki/Adderall https://en.wikipedia.org/wiki/Psilocybin#History

This makes very little sense unless on purpose. I mean, like what, people been doing it for millenniums and still we got where we are now, and not because of downsides of its use, or what?

Modern drug laws came about in the 1970s, at the height of hippies on psychedelics trying to overthrow the government.

People in power fear losing their power, and they saw these drugs as a threat.

The weirdest part of the whole thing to me is that they outlawed Cannabis, Psilocybin, and LSD, but kept cocaine legal with a prescription under schedule 2.

bwestergard · 10m ago
A family friend who was an ophthalmic surgeon once explained to me the cocaine was long the default anesthetic for eye surgery, and thus it had an accepted medical use (which was the criterion for Schedule 2). Sounds at least plausible to me.
pstuart · 1h ago
But those modern drug laws picked up where the older drug laws petered out, and in both cases they were intended to punish their users, not protect them.

To bang a fairly weathered drum, this is largely a matter of conservative policy. Psychedelics were far more common in leftist circles (some might argue that this is cause as opposed to effect - mind-expanding experiences tend to shift politics towards that end of the spectrum).

This means that if you wanted to use the law as a political cudgel without being accused of thought-policing, you could outlaw psychedelics and be confident that the blast zone would exclude the politically faithful while locking up loads of political undesirables; like hippies, panthers, etc.

Of course, these days you have right-wing podcasters discussing DMT with billionaire CEOs, so it's a little trickier. Thus the tentative steps toward legalization.

It's politics and optics. But as someone taking a schedule 3 medication that is really a schedule 1 in disguise (sodium oxybate) I wonder why they couldn't use the same tap dance for psylocibin or MDMA. Slight chemical modification to adjust absorption rate but same active ingredient. I think we only get away with this because it's prescribed so rarely and out of public consciousness. It's incredibly effective at treating a pernicious condition.

I don't have depression, but the first time I used psychedelics was so emotional helpful that I strongly suggested for depressed friends. I corrected that mistake hours later, after realizing that the risks are low, but life changing if it happens. However, I will never forget that feeling. I've used it again in the following years, but the results faded and it became boring for me.

What are the low-but-life-changing risks?
anon6959 · 40m ago
Exacerbation (and possibly development) of mental illness like psychosis, bipolar disorder, or schizophrenia is entirely possible.

Along with two other blokes, I got interested in psychedelics in high school. Took one medium high dose and wasn't right for a few months. Never in my life did i ever experienced paranoia, delusions, or hallucinations that are genuinely hard to separate from reality, but I did after that.

Intense psychedelic experiences can fracture what you once knew as "reality" allows all sorts of ideas to float into your mind, with equal possibility. This might be helpful and give you more flexible thinking (helpful for depression) but it also leaves you incredible vulnerable to all sorts of garbage ideas that you never would have considered otherwise. ie conspiracy theories or straight up delusions about the supernatural. Remember: It's not paranoia if you genuinely believe they really are out to get you!

Fighting these garbage ideas is a lot of work once they take hold, but you'll only know too late if you were vulnerable, and worse, if you can successfully align your understanding of reality with most other people.

I got extremely lucky that I stabilized. I'm convinced part of this was only doing it one time. My two co-experimenters took many trips with various doses are still in and out of mental hospitals years later. Psychedelics are incredibly potent and nobody really understands them very well. A lot of what is written on the internet ignores, downplays, or denies the very serious risks to your philosophy of mind and mental function. Its like playing with fire when you don't have heat sensation in your hands.

Several other comments on this page echo these warnings. One even claims there is an 18% chance you could go from depressed to schizophrenic. I have no idea where that figure came from, but the risk is certainly not 0%

Aurornis · 2h ago
The risk is that it’s a false idea triggered by the psychedelic.

Maybe a better example would be my friend who took psychedelics and then believed he was in communication with Elon Musk. This one is more obviously a false idea, but nevertheless he was convinced it was real for a period after the psychedelic experience.

There’s a mystical concept that psychedelics open your third eye to see the world as it really is or something, but psychedelics are notorious for giving false ideas and making them seem like revelations. It’s obvious when it’s nonsense (like telepathy with Elon Musk) but it’s less obvious when the implanted idea is something like “your husband secretly doesn’t love you”. Another strangely common report is the belief that people around you have been replaced by clones, which can get scary very fast if the person can’t separate the idea from reality.

AppleBananaPie · 1h ago
Yeah I agree with you 100%. it's interesting folks immediately taking the experience and result at face value when we understand so little about what's happening, even without psychedelics is most cases.

In the referenced anecdote it could be as simple as an excuse needed for someone who's been thinking about it for years. Though maybe that's enough to be a benefit

Anyway I like your example and look forward to what is learned about using psychedelics to help people :)

armonster · 1h ago
It sounds like your friend had a predilection for psychosis. I feel like the nice things about psychedelics is that they don't alter my processing too much (as compared with other drugs), moreso they just give me different 'inputs' into my senses / experiences, and then I process those.
Aurornis · 22m ago
> It sounds like your friend had a predilection for psychosis.

No prior history of any mental illness in him nor any of his family.

This is a common excuse: Blame some hidden susceptibility, not the drug. It doesn’t matter what it was, though. The drug caused it and there were no warning signs. Fine before the drug. Not fine after the drug.

> after realizing that the risks are low, but life changing if it happens.

I think these risks are more common than was previously discussed on the internet. For a long time reports of very negative experiences were dismissed, laughed at, downplayed, waved away as symptoms of something else, or excused as something positive but mysterious.

It’s becoming more acceptable for people to discuss their negative experiences and not get downvoted or attacked for sharing them.

bongodongobob · 1h ago
Negative experiences have always been a part of it. It's half the point. Negative also doesn't mean permanent, which is extremely rare.
nwienert · 52m ago
Not that rare, anyone with predisposition to psychosis/schizophrenia has a high risk of permanent effects, and that’s not that small of a segment of people, and nearly unknowable beforehand.
Aurornis · 1h ago
> Negative experiences have always been a part of it. It's half the point.

This is the type of dismissal and downplaying I’m referring to.

My friend descended into psychosis after taking psychedelics. It was not “half the point” and not helpful to his life in any way.

FollowingTheDao · 3h ago
Many people say the first time they use Prozac that it was so helpful they recommended to their friends but then after a while it wore off.

How do you think psychedelics work? They activate the serotonin 2a receptor. It’s nothing but a different drug that effects serotonin. Except it does it more intensely but like all these drugs that act on receptors they wear off because of something what’s called receptor density changes.

For 70 years, we’ve been trying to manipulate receptors into making people feel good. It’s a losing proposition and it’s time to. We changed our thinking. For instance, if these people do have serotonin deficiencies, which is still possibly the case, what is it? That’s causing these deficiencies? Is it low, zinc, low B6, genetics, infection? There’s so many other things that we know that this could be, but we don’t try it.

milchek · 6h ago
Anecdotal, but about a year ago my wife participated in a psilocybin trial at a university here who were looking at patients with severe anxiety. It was her last hope after trying therapy, various supplements, as well as dietary and lifestyle changes, etc

It has been life changing for her, but one thing she tells people now is that what also helped was that it was facilitated with a trained therapist there during the session for guidance to make sure she didn’t “get stuck in a loop.” There was also many sessions pre dosing day to optimize the result.

She would highly recommend the treatment and hopes it becomes mainstream soon.

sampl3username · 4h ago
The point of music during a psychedelic experience is to provide a reference for the passing of time and to help with progression of thoughts. Music guides you through your thoughts, avoiding loops, by providing a changing texture, melody, rythm, and story.

This is on top of the other effects of music, such as emotional effects.

ThinkBeat · 2h ago
If I understand what you wrote correctly, Your wife did not try any traditional medication to treat her anxiety? Or is that included under "supplements"?

If so the term "lost hope" is not in my opinion accurate.

I am quite happy that it worked and it is a better alternative than medication, I certainly do not think that medication is the cure all, or optimal.

esseph · 2h ago
> If so the term "lost hope" is not in my opinion accurate.

What an absolutely asshole statement, which also shows an absolutely profound misunderstanding of suicide prevention and care.

Edit: Core belief of suicide ideation is that hope is gone. This is often (but not always) a perception. There may always be more things to try - but that's irrelevant to the person that is dead because they could not see another way.

Technically, what is the approximate dosing regime?

How often, for how many days, how much (=how high?)?

Is this a therapy with an end or do you have to take mushrooms forever?

yesseri · 5h ago
Is it possible to have a placebo group when doing a study on psilocybin? Would participants in the placebo not notice the lack of psychedelic effects?

EDIT: In the original link it says the placebo group received a much lower dose, so that seems to be one way of doing it.

AndrewThrowaway · 4h ago
Then again what if showing some funky hallucinogenic images/movies would have the same effect on some people? We surely know that people can go crazy (so have psychological effects) in cults and similar settings. What if intense visual/sonic/etc stimulation, visual distortions etc. together with messaging like "it will change your life and cure your anxieties" is the key in this therapy?

I sincerely hope this is not at all how any of this works. That sounds like a recipe for paranoia.

That's not so much a placebo as a head to head test of different effects? I think you'd do it in a new study entirely
sorcerer-mar · 4h ago
That isn't how these studies are being done... because yeah, it'd probably confound the results.
OldfieldFund · 4h ago
One way is using niacin in high doses, also known as vitamin B3, as an active placebo to induce a sensation of heat and cause the skin to flush red, which is a typical reaction to tryptamines.

The rest is a regular placebo. It can be a really strong thing when you are feeling hot.

mock-possum · 5h ago
sounds like in that case you’re not testing the efficacy of high versus sober, you’re testing heroic dosing versus micro dosing.
sorcerer-mar · 4h ago
There are also studies that test against placebo. There have been lots and lots of trials on these things with different designs that make different cost/benefit tradeoffs.

A difficult one with psychedelics is as-mentioned: people can easily "break the blind". But if you want to eliminate that problem you can instead do a micro vs macro dose, in which case you're measuring a slightly different thing.

mehphp · 5h ago
Anecdotally, I didn’t get severe anxiety and panic attacks until immediately after trying mushrooms. I didn’t even have a bad trip, but the next day something was off and I never truly recovered from that.
throwmeaway222 · 52m ago
Thank you for posting this. While not everyone's experience is the same, after hearing all the hype I was inching closer to trying this... but this confirms that it's not a magic bullet and there are dangers. I don't have any specific mental issues right now, so there's also probably no reason to try it. The only thing I wish for, at 45 yo, is to have a faster to adapt mind like I had when I was younger.
kbos87 · 3h ago
Yes, the one time I've tried mushrooms it was a very unpleasant experience. For weeks I was left feeling like I had done some permanent damage to my mental health. I eventually got past that feeling and there might be a point I try them again, but not without professional guidance. Psilocybin is powerful and not a remotely recreational thing (for me at least.)

Ditto. They contributed to long-term trashing the psyche of a relative and we have a really strong history of such issues, stuff like schizophrenia that they can trigger. It’s an under appreciated risk.

In general, even with genetically inherited disorders your chances of developing most conditions drop from 54% to less than 18% in low stress environments.

Epigenetics are weird, but if you are past 35 without symptoms than you should be fine without medication (know several people that weren't as lucky.)

“18% chance you go from depressed to schizophrenic” (in reality this risk is going to vary across a distribution of risk) is still not favorable odds the way I see it.

The 3rd generation medications keep his cycles under control fairly well. Note, prior to being processed by our medical system. These same a--hole sycophantic dealers would target vulnerable people with BS treatments all the time.

Talk with your doctor, get out for a walk every morning, and try out cognitive behavioral therapy when you are ready. =3

I have a family member who has never been alright due to moderate psychedelic and heavy marijuana use in college. Maybe some people are fine, sure, and maybe this is even a rare outcome, but the denialism bothers me when I personally know that they can, at some unknown rate, turn someone schizophrenic and ruin his life. I wish we could get him treatment but he's not high-grade enough to be involuntarily committed but paranoid schizophrenics who hate and distrust their family don't respond well to "hey we should get you treatment."

I have a friend from college who smoked too much marijuana during lockdown back in India. Thankfully the insanity cleared up after a few weeks to a month clean of it, but not all are so lucky.

The denialism and propaganda campaigns bother me. As pro-legalization as I am, I personally have never and will never use drugs. They are dangerous and unnecessary, and I resent those who would influence others' decisions to do something high-risk and potentially very damaging because they want to get high.

Some have genetic vulnerability to addictions, and others latent disorders do manifest.

Very common side-effect for people that try strong hallucinogens and or use malformed neurotransmitters.

The find-out part happens later =3

Joel_Mckay · 1h ago
Many people with psychiatric challenges (both acute or chronic disorders) will often seek self-medication options. Marijuana is indeed a mild hallucinogen, but you are correct in that many hard drugs can trigger a psychotic episode. Often illegal dealers lace the stuff with addictive compounds that cause severe problems during withdrawal.

Having a family member with active untreated disorders can tilt the odds out of ones favor, but those with intellectual gifts also tend to be more resilient to such situations.

>The denialism and propaganda campaigns bother me

Understandable, after a few years people see the same excuses, exploitive scams, and rhetoric. The Sackler family ruined a lot of lives to capture that money, and I guess a few psychopaths saw a business opportunity.

Anecdotal, but I know someone who suffered major depression and was hospitalized multiple times. Their medication wasn't working and neither was therapy.

They discovered mindfulness meditation and in combination with becoming a more moral person, limiting music, eliminating social media and unwholesome entertainment, and practicing small acts of charity multiple times per week they were able to overcome their depression. It's been almost 15 years since they've had any symptoms.

seneca · 3h ago
That makes a lot of sense. May I ask, why "limiting music"? Was it just a specific type of music, or did music in general have a negative effect?
phyzix5761 · 3h ago
The way they've explained it is that we listen to music because we have a desire for sensual pleasure. And constantly giving in to desires, in general, creates a dependence where we're never satisfied with what we have. This dissatisfaction, when it becomes strong enough, leads to depression.

They practiced something called guarding their senses where they limited the amount of sensual pleasures they exposed themselves to and this calmed down their mind down to the point where even small things like the taste of ordinary food or having a conversation with a friend felt really satisfying.

You added the "just". Becoming a better person is probably the best thing you can shoot for, though obviously it's not a trivial process and requires significant effort and intention. I mean, what else can you do? You're the one that has to live with yourself.

Even if the whole world is going to shit, if you desire the happiness and wellbeing of others, as a deep internal orientation, this itself is its own form of happiness which is not subject to anything external. Since this thread already has Buddhist vibes, you don't have to take my word for it and can refer to metta (loving-kindness) as its own practice in addition to mindfulness.

The really interesting part is they are Muslim. They said that learning about Buddhism helped them understand the core of Islam and helped everything click into place.

The native Muslim tradition akin to what mindfulness meditation is doing would be Sufism. There are still Sufi traditions extant, but in many places they're being attacked by militant Islamic fundamentalists.
phyzix5761 · 3h ago
The way they've explained it is that immorality is usually based on desire and aversion. And constantly giving in to these things creates a dependence where we're never satisfied with what we have. Having a structured moral code that allows for observing these mental qualities without giving in to them eventually leads to their reduction because we're breaking the habit pattern. Once your desires and aversions are reduced then you become more satisfied with what you have; ie eliminating depression in their case.

The study design does try to mitigate blinding issues and expectancy effects, but with half of the participants reporting past use of hallucinogens, this is not going to be very effective blinding.

A majority of your low dose 1st group likely very much realizes that they're on the inactive dose.

alphazard · 4h ago
There's an argument to be made that traditional blinding and placebo techniques are not really relevant for interventions targeting mood or personality. e.g. anything that makes you feel better is an effective mood intervention, by definition. "blinding" in these studies is really just going through the motions to make certain authorities happy.

I would be more interested in polling the close friends and family of study participants and asking them about perceived changes. Instruct participants not to tell anyone about their experience in the study (whether they think they got a drug or how much).

It looks like the study tried to do something like this with "session monitors" who interviewed the participants the day after. They call it double-blind, but it's more like single-blind because the 3rd person assessment is the outcome measure.

sorcerer-mar · 4h ago
The issue with relying on placebo effects is not that they aren't real/don't work (everything you said also applies to e.g. a painkiller), but that they are very context-sensitive. Deploy that drug to an individual or population with a different belief framework or contextual information about the therapy or their condition, and you won't get the desired results.

The design you mention is really interesting! Have you seen this done anywhere?

demiters · 5h ago
Is it even possible to solve the issue of there being no convincing placebo? Would a different hallucinogen like 4-HO-MET work, where the visual experience component is similar, but the visceral effect on consciousness and thought patterns is less pronounced, almost sober like?
hattmall · 4h ago
Or they could give them a different psychedelic to test the efficacy of psilocybin specifically would be my thought.
_alternator_ · 1h ago
Seems that most hallucinogens have similar benefits, with “more powerful” drugs having a more profound effect. Here’s a study on social learning in mice [1]. TLDR: length of trip correlates strongly to duration of treatment effect (eg 6 hour trip -> 1 week effect, 36 hour trip -> 6+ month effect IIRC).

Psylocybin isn’t the most studied because it’s likely to be the most effective drug. It’s because the therapists/grad students can work an 8 hour day instead of providing 12+ hour care for LSD or multi-day treatment with Ibogaine.

My dad is a boomer who's strongly (and I think uncritically) against non-medical use of all drugs except alcohol (and he himself doesn't drink). He would be hesitant to do this under medical supervision, but he definitely wouldn't just do it "on his own".

Besides, he's kind of a closed off person who has a lot of emotions he just avoids dealing with, even more so since the cancer diagnosis. He definitely needs a trip sitter, but he has few friends (certainly none who could do that competently), and no one in our family could fulfill such a role for him. Maybe I could for someone else, but my relationship with him is too complicated for me to do that job well, I think. :-\

To top it off, my dad's cancer is in his liver, even though he never drank much at all for dietary reasons (he was on a strict keto diet for ages). I would worry about the possibility of toxicity with introducing new drugs without medical supervision.

Taking psychedelics allowed me to shed years of guilt and my own historic personality to become a more open and grateful person. I think some people have psychologies built on strong foundations that if shaken by psychedelics, cause more harm than good.

Welcome to year 30 of trying to prove psilocybin works for psychiatric illness. And still in the pilot stage.

Even taking the data at face value, the trial cannot disentangle the drug effect from expectancy, psychotherapy, and statistical noise. The enormous effect sizes are almost certainly inflated, multiple-comparison error is uncontrolled, and the participant pool is highly self-selected. Until a preregistered, parallel-group, active-placebo, adequately powered study with blinded independent raters replicates these findings, their practical value for routine cancer care remains minimal.

It’s so interesting to see how strong the drive to prove something works is, overriding everything. As a clinical psychologist, I would welcome this kind of therapy if it worked. But this is just sad. It’s just like listening to people claim that ivermectin can cure everything.

Show me one place where this therapy is conducted by people who haven’t "drunk the Kool-Aid," and I’ll be impressed. It’s so frustrating to work with actual patients and see how much these therapies really don’t work in reality. These kinds of biased studies pop up all the time without actually panning out. I’m starting to think that people promoting therapy, giving false hope, and spending money on research like this should be viewed as corrupt and evil.

>Welcome to year 30 of trying to prove psilocybin works for psychiatric illness.

That is true, but it misses some important nuance: the war on drugs has effectively eliminated the ability for legitimate researchers to do significant research on these criminalized drugs.

For example, for me personally, a mild dose of marijuana is as effective as Zolpidem (Ambien) as a sleep aid, but without the lethargy and mental fog the next morning.

Most people involved in it are aware at some level that this is at best suspect and at worst a deception designed to push legalization. Same as the “health benefits of marijuana” crowd who violently deny the risks, addictive nature, potential to induce schizophrenia (temporary or permanent), tendency to make people lazy and obese, etc.

Legalization has never been a question of “is this good for people?”

So am I, of both "hard" and "soft" drugs. I'm just pointing out the ridiculous approach some people choose to take rather than arguing from principled grounds. It's also a dangerous one: "we shouldn't use state violence against people who use X" is a moral position. "I'm going to spread lies that may lead more people to use dangerous substance X because I want to get high" is a very immoral one.

I think I agree. But I come at it from a different angle. I only care if proposed therapies actually work, when people claim they do. I think the state has a horrendous track record of deciding what people are allowed to do with their own life. And I think drug enforcements are a waste of resources. I think almost all drugs are terrible and should never be taken. To me, all of these are simultaneously true.
johndhi · 4h ago
Why do you say the effect sizes are inflated?
jtrn · 4h ago
Due to a small, self-selected sample, biased toward educated, prior hallucinogen users, inadequate blinding, p-hacking via uncorrected multiple tests on 17+ outcomes, and crossover design flaws that confound long-term effects with intensive therapy.

Similar psychedelic therapy claims—for LSD/psilocybin alleviating cancer-related anxiety/depression—have echoed since the 1950s-1970s, yet they've never panned out into practical, scalable clinical therapies. This alone should raise a MASSIVE Bayesian statistics red flag, due to prior discount: with decades of unfulfilled hype. At this point new evidence requires extraordinary proof to update our view.

If such massive effectiveness were true, it would blow what we already have out of the water, and I would be the first to promote it to my patients. But you know what they say when something sounds too good to be true.

cmrdporcupine · 4h ago
Thank you for this. I am neither an advocate nor against psychedelic use in therapy but as a person who has consumed these things in the past, my own experiences make me entirely skeptical of people who put on an advocacy hat around any particular chemical. Especially psychedelics like psilocybin which are extremely unpredictable.

When I was a teen a friend gave me an analogy that stuck with me. In much older computers (e.g. C64, Vic-20, etc), they'd behave "interestingly" when you mucked around with the physical circuit board or there was a fault. E.g. if something short circuited because a screw was loose in the board, or a cartridge was halfway in or a chip partially desocketed, etc. Characters would appear in random places, or the machine go through odd loops and so on. And to someone who didn't know how the machine worked, there could be a certain "magic" and a "pattern" to this. But clearly you'd be missing the point if you thought you had "enhanced" the machine this way.

LSD and psilocybin are kind of like that, but for your brain. They short circuit and alter pathways. In ways that can be entertaining but you're entirely missing the point if you try to assign a higher meaning to them.

Our brains are expert pattern-finding machines, and produce causes and reasons even when there are none. For some there may be value in the experience of altering the operation of your brain to get yourself out of a stuck pattern, I guess. But I am not sure the very random stochastic nature of the whole thing is ... medicinal.

Figure 3 is suspicious. Even the placebo arm has much better scores for depression and anxiety from baseline?
Aurornis · 4h ago
This happens in every depression study: Placebo effect is extremely strong for depression.

You can even collect depressed people, do nothing at all, and when you survey them 6 months later the average scores will improve. This is because depression is, on average, an aberrant condition and the average patient will tend to revert toward the mean.

However, psychedelic studies have a bigger problem: Psychedelics trigger false feelings of amazement and wonder, feeling like something magical has happened. This is like turbo placebo when you tell people that it’s a depression treatment. Maybe that’s a valuable therapeutic effect, or maybe not. There’s a lot to explore, but from all the studies I’ve read I’m not as bullish on mushrooms for depression as the headlines would indicate.

hellohello911 · 4h ago
Setting aside the psychedlic aspect, do you think figure 3 supports the study's conclusion?
Aurornis · 3h ago
If this is your first time reading depression studies then it’s going to be surprising to see both groups improve. This is normal and expected.

The key indicator of efficacy is the difference between groups. In this case there is some difference between groups but it is small.

While the first 5 week post treatment actually looks impressive, I don't think the treatment arms being essentially the same after 6 months supports the conclusions of the study. Unless we backpedal and say the inactive grouo was microdosing (which has its own baggage...)

The study mentions they administered 30 milligrams of psilocybin for 70 kg of body weight. Does anybody know how many grams of dried mushrooms that is equivalent to, roughly?
awithrow · 4h ago
A good ballpark for dried shrooms is roughly 1% psilocybin by weight of dried shroom, so about 3g. That said, it's going to vary a lot shroom to shroom, genetic to genetics, and species to species. Could be as high as 6g for more mild strains and as low a 1g for something like pan cyans.

You’ll be tripping balls on that amount. 5g is close to a heroic dose.

throwaway330935 · 3h ago
I've been doing some recent research and testing, and here's what I have found: I'm talking about the "Penis Envy" strain, which is quoted as being ~30% more potent than typical. 2g is the edge of where I start getting visual artifacting, and only sometimes. 3g, which I have not tried, was quoted as being towards the upper end of a "theraputic dose", and 6g as the upper end of a recreational dose. Some friends with much more experience consider 1g to be microdosing, FWIW. 0.25g I can't feel at all. .5g I start to feel some euphoria and 1g to 1.5g I start to feel "high" but with no noticeable psychedelics or just minor visual artifacting when I'm reading.

I don't really have anxiety or depression. I do have a fairly high stress family life, wife and kiddos have lots of issues. A few weeks ago I had 2g on an empty stomach on a Sunday and I just listened to music for ~4 hours and it was like I had a vacation. I hadn't enjoyed listening to music so much for 20-30 years. Also, I seem to feel kind of sleepy when I'm trippy, but afterwards I'm wide awake for 4-5 hours. So evening dosing is best avoided.

It's kind of great, for me personally, living in a state where it has been decriminalized.

Here's a rough breakdown from Claude:

"[...] psilocybin converts to psilocin in the body at roughly a 1:1 ratio by active effect [...]

Psilocybe cubensis (most common): Contains about 0.5-1.0% psilocybin by dry weight. Since psilocybin converts to psilocin in the body at roughly a 1:1 ratio by active effect, 30mg of psilocin would be equivalent to roughly 3-6 grams of dried P. cubensis.

Psilocybe semilanceata (liberty caps): Much more potent at 1-2% psilocybin content, so you'd need only about 1.5-3 grams dried.

Psilocybe azurescens: Even more potent at 1.5-2.5% psilocybin, requiring roughly 1-2 grams dried.

Important caveats:

- Individual mushrooms within the same species can vary by 3-5x in potency Growing conditions, harvesting time, and drying/storage methods all affect potency

- The caps are typically more potent than stems

- Fresh vs. dried makes a huge difference (fresh mushrooms are ~90% water)"

Have to note that the paper is from 2016; for those really interested, it's good to read recent review papers.

Another positive anecdote for me

I am more empathic for weeks after doses of psilocybin. Getting there doesn't rely on any hero trips, no fractals, just maybe to the point of seeing more vibrant lights for a few hours. They used to hurt my stomach which would throw off a trip while dealing with that, and I still avoid eating stems, but it looks like I have tolerance to that now.

Nothing supremely insightful, I mostly ignore my mind's attempts at epiphanies and the false feelings of clarity, I wait till music festivals to consume them and just enjoy the vibrant lights and echo-ing sounds. Just to the point where conversations and ambient noises from further away than expected are being amplified and spliced in to things happening much closer to me.

Recreationally, I like the people I attract when I'm feeling the effects of psilocybin. I'm far too analytical in default mode, not nearly as much as when I was a bit younger, but still a far cry from where I would prefer to be. Its like I "null route" all of that and am more present to how people feel or want to feel. Its kind of crazy and obvious when it wears off, I respond to stimuli differently, or ask about things I don't really want to ask about. Less "vibes" in the moment and more "analyze" like noticing incongruences in people's lives and asking about that as a form of smalltalk, when it would be better off ignored. People respond normally, but I can tell it doesn't give them a spark of warmth like the vibes version of me does. Wasn't a goal or something I was aiming to work on, just a side effect I noticed over time.

I also use other kinds of psychedelics but I didn't want to pollute this comment with more anecdotes.

mauriciokeita · 5h ago
Why is there no more recent studies on that?
Joel_Mckay · 5h ago
Because usually the "euphoria" people feel is their biology failing due to mild poisoning. It is why most people will often upchuck within a few minutes of ingestion.

People may think they are finding enlightenment, but are no different from the local deranged squirrels aggressively howling at passerby after nibbling Amanita in the fall. Apparently the squirrels use the mushroom to help preserve food stores, and it doesn't poison them as severely (often fatal for humans.)

Paul Stamets is a weird dude, but his work contains some profoundly detailed observations.

People need to think about Fungi as closer to animals that don't move on their own, and acknowledge they rapidly adapt genetically to survive. Pretty to photograph, but often far more complex than people like to admit. =3

>Amanita

It's an entirely different class of hallucinogen. I don't have personal experience with it but I have done other dissociative hallucinogens and his take is likely largely true (though I wouldn't argue with someone saying they felt euphoria on it). The problem here is it's the entirely wrong mushroom.

I can assure any doubters that psilocybin on the other hand has legitimate euphoric effects.

Joel_Mckay · 3h ago
The psilocybin containing variety also naturally grow in our yard, and the Amanita is an invasive variety. The "high" people feel is a chemical lobotomy from mild poisoning, and onset of renal failure. Hence why you feel nausea and often erupt out both ends if ingested (especially bad if allergic to a specific fungi.)

I asked for 5 citations not sponsored by dealers that he claimed were available, and my post was flagged. To be fair, I would also accept 3 double-blind medical citations of reasonable quality.

You can't argue with the irrational, as hitting yourself in the head with a brick also causes similar results. lol =3

Aurornis · 4h ago
Anecdotally, I know several people who have tried mushrooms and/or ayahuasca for depression in recent years and their results are nothing like the glowing Internet reports.

The worst case is a friend who became disconnected from reality for a very long time. Went from atheistic to believing in mystical ideas. He thought he was able to see and sense things that we could not, like auras and secret messages. He was getting better last time we checked but he’s hard to get in contact with now. No prior hints of psychosis or family history, just a psychedelic induced mental illness.

The other anecdotes were not as dramatic, but also not as positive or free of side effects as studies like this one would make you think. Multiple stories of extended periods of derealization or anxiety attacks that started after the trip. There are similar comments here throughout this comment section.

There was a time when sharing these negative stories was met with disbelief and downvotes. I think as it’s becoming more common people are realizing that the interaction between psychedelics and depression isn’t as great as it seemed for a few years when they were virtually being promoted by podcasters and social media influencers as a novel cure for depression.

chuckadams · 4h ago
I think a lot of the negative reception to negative anecdotes were because they were often in the context of legalization. "I know someone who went crazy after trying $foo so we should still lock people into iron cages just for the crime of possessing it." Debate tends to get polarized when doors are being kicked down. Academic studies that are disconnected from culture wars don't tend to provoke such responses, probably because they don't tend to reach the general public in the first place.
Aurornis · 3h ago
> because they were often in the context of legalization. "I know someone who went crazy after trying $foo so we should still lock people into iron cages just for the crime of possessing it."

I think that’s what people thought when reading negative anecdotes, but I definitely didn’t see a lot of suggestions that we lock people up.

The same thing happened for marijuana: Any mention of negative effects would bring downvotes, scorn, and disbelief pre-legalization. Then once it was legal it became acceptable to say that marijuana wasn’t a panacea and using a lot of it was actually a problem.

Before this change, it was common to read highly upvoted anecdotes here and on Reddit claiming everything from medicinal properties to fixing depression to improving driving skills (an actual claim I saw here and on Reddit multiple times). Now it’s widely acceptable that frequent marijuana use is not good for mental health and wellbeing, but that was once a thing you could not say on the internet.

I'm sure it's nothing like a panacea, but I've lost count of the times in which getting some context behind a report of a bad experience shows recklessness or just plain old bad decisions.

It also works the other way around, people even talk about how years of therapy didn't help but psilocybin did, and few seem to consider that maybe it was a combination of both? Perhaps all of that therapy that "didn't help" set the stage for something else.

General problem with anecdata I guess.

gavmor · 1h ago
Yes, although—within a specific range—mild "hormetic" stress or departure from baseline can lead to adaptive and beneficial effects in organic systems.

Hormesis is characterized by a biphasic dose-response: low-level exposures to stressors (toxins, temperature, exercise, dietary restriction, etc.) are those which stimulate adaptive beneficial responses, eg exercise, ischemic preconditioning (short bouts of reduced blood flow improving tissue resilience), and dietary energy restriction.

Rather than negating homeostasis, we can say that hormesis "refines" it: mild, intermittent stress can make us resilient through larger future perturbations.
