A few months ago, we had a support group going at my clinic, with several patients with various diagnoses which are not directly discussed. We also had a presentation on sleep hygiene by a visiting psychiatrist. One of the newer support group members was openly promoting his love of smoking a joint and a cigarette and chilling out in the morning, and the psychiatrist said "cool, you do you!"
Then the next week, the clinician leader of the support group laid down a few ground rules for the new members, one of them being "if you show up while you're high, then you'll be gone just as quickly".
So I think it's safe to say that there is a range of opinions and attitudes among clinical professionals.
I have a friend who makes a good tech salary and lives in $LARGE_CITY, and she and I have compared notes on mental disorders over the years.
She enjoys her drugs, of all kinds. She worked hard to connect with a psychiatrist who could both prescribe the sorts of drugs she's into, and also not shame her for the recreational drugs she does on the side. She pays out-of-pocket for the privilege.
It became apparent to me that she's not really into treatment of her condition or healing, or repairing her relationships with friends and family. She just seemed to be on a hedonistic journey of seeking pleasure.
So you can decriminalize and reschedule all the drugs you want, but people will self-medicate, and find dangerous uses. People who use illegal or OTC or alternative treatments will not always report those to their physician or pharmacy. Even if they do, all interactions are not known, but many dangerous ones can result from trying to put someone on psychotropics while they're under the influence of something else.
