I found the question come up on both communist and anarchist subs, and the difference in responses was quite striking.
As a longtime PTSD sufferer who self-medicates to the hilt just to do simple things like fall asleep or leave the house, the idea that I would either lose access to, be forced underground, or prosecuted for my recreational habits terrifies me.
I understand the rationale is in a functioning communist state, I would no longer feel the need for those drugs. Does it follow the science of recreational marijuana, psychedelics, ADHD, anxiety, depression, etc.? Or is the ambition to ween everyone off? And does that apply for all manner of distraction and entertainment as well?
Recreational drugs should be freely available to the degree that the community's health apparatus can catch and correct addiction. If people have a monthly checkup then we need to carefully regulate any drugs strong/addictive enough that someone can spiral into addiction and harm themselves/others within a month.
Games, art, and entertainment should be the ultimate goal of communism. They're not the top priority - that's food, shelter, medicine, education, etc sustainably for everyone - but those aren't bottomless needs. Eventually once those are all solved, we can turn fully towards producing entertainment.
(And for a particularly wild thought - there's only a finite amount of entertainment hours a person can consume per day, and our production can exceed that. The final scarce resource is human attention span to pay on each other's art projects.)
