As a non American this seems extremely obvious to me so idk what the struggle session is about. Saw the discourse a bit on Twitter an this isn't about people that need and use drugs for medical reasons to function. It's not about saying addicts are unwelcome on the struggle or that you shouldn't be doing drugs or drinking with comrades

But in an actual protest or community outreach let's say if you, by choice of recreational drug or alcohol use that could have been avoided, aren't as cognitively and hand eye coordination THERE as you can be, then you are increasing the possible danger for you and your comrades and reduce the efficiency of your organizing.

I really don't know any serious successfull radical orgs, now or historically, that haven't been against showing up to party work drunk or noticaby high as a general rule.
