I've been thinking about this for a while now and I've recently rewatched Leo's video on using psychedelics for personal development which made me eventually raise this question: why alcohol couldn't be used for the same purpose? Given that it's used consciously, similarly what Leo said for psychedelics, drinking some safe amount of beer (~1 liter of 5.4% IPA for me) alone while focusing inside and being prepared for it, for example, was able to give me sudden insights on things were I was mentally stuck, permanently relieve stress in the inside, and also filled me with warm love (to my own surprise).  Sometimes I share the same experiences when drinking pu-erh teas. I don't tell that it's on par with psychedelics (I haven't tried them, but based on what I heard about them, I have some vague assumptions about their effects) but might make an argument for "validating" the use of alcohol within some boundaries, as a lightweight and fully legal alternative.
