There are a ton of articles out there, most seem like clickbait, but there are studies that have been done such as this one [1] which say that LSD has had a positive impact on alcohol abuse. I'm not saying this is the cure, but I do think further studies could prove beneficial.
Edit: Added pdf of paper [2].

Point of fact, addiction is a disease and must be treated like a disease. This is pretty mainstream and not really all that controversial. The issue we're working through, glacially, is that in the US healthcare is for-profit and junkies are not profitable. So we just.... throw those people in the garbage. I think that's both immoral and economically wasteful. I know former junkies. Personally. And they're not garbage-- they have value and if you can get them well, they want to live a productive life.
The plain fact of the matter is that there's no business case for treating these folks-- the government is going to do it or nobody is going to do it. And the status quo is "Fuck it, send them to church. I'm not paying for a bunch of crackheads to get clean. They need to find jesus." Which is another way of saying "Let them eat thoughts and prayers."
