Do you mean why vapes aren't allowed to be sold in exciting flavours in a lot of countries?
Because what happened there was that 'strawberry kiwi', 'banana ice', and 'miami mint', and whatever fruity flavour in a colourful package you can come up with, turned vaping from something adults did to quit smoking tobacco into the biggest hype amongst teenagers since fidget spinners. Only they get addicted to nicotine as a bonus, and switch to 'proper' tobacco in their senior years.
Even with a complete ban on those the damage is done, and all across the globe society is now dealing with a huge profitable underground Snapchat-enabled market geared solely at selling the equivalent of a pack-a-day habit in nicotine to kids. (The ban helps to gradually denormalise vaping again, so it is good to have in place.)
I'll never understand why adults partaking in a particular vice can't enjoy different flavours (unless the vice is alcohol).
