because people in those states can act unpredictably and are thus unreliable. you don't want your surgeon to be tripping balls.

In my opinion it’s because in the past human beings needed to be constantly working or assisting with a group in some capacity in order to ensure mutual survival for the group. Let’s say a village.

Activity which is not seen as being productive or could be construed as lazy has a stigma around it because it casts doubt on your ability to contribute to society.

Obviously none of this applies in the same way these days but there is a kind of primal conflation of intoxicants and laziness. Laziness is bad and so consuming intoxicants turns into a moral issue.

These attitudes are very deeply ingrained and although they can shift a bit as people become more liberal the deep suspicion remains.

I think the mindset of a society is hard to change. We do see some progress towards the use of psychedelics for mental treatments which I think is great(at least in my area of the world). Is it enough ? Not to my taste but it's progress. I can't wait for people to have access to that kind of help!

I'm still using mushrooms from time to time to deal with personal issues, trying to find a different perspective on my own, it has helped me numerous times. I think it also helped me reduce my overall stress and prejudice.

I would suggest you also try to find different perspectives on how people got different opinions on the subject. I really don't think being aggressive towards them the way you have been helps anybody. If anything, your opinion/facts are discarded quicker because you dont appear as a respectable source of information. You appear too emotionally connected to the subject. Especially to people who may be scared or closed to those different ideas.
