Capitalism has a deep-seated taboo against taking recreational drugs. So strong is the taboo they will ruin your life and exile you from mainstream society for doing something recreational.
This is changing a bit as the scientists tell them there is basically no reason for this. But the scientists meet with resistance from entrenched cops, judges, lawyers, who are very 
about it.
What’s the materialist explanation for this moralistic taboo?
also why many stimulant “nootropics” are gray market legal as well as kratom. pharm companies would love to make kratom go away and put everyone on suboxone for life but its become a “white, disabled veteran” and “white, boomer aunt” pain reliever which makes efforts to ban it very frustrated.
also it being basically “matcha tea opioid you can’t OD on” gives it less allure for the conservative “drugs icky” crowd
and the kratom advocacy group is made up of retired congresspeople and ran by Pelosi’s son so there’s that web of handshakes and back patting
