I have had interesting experiences with low (but not micro) doses of LSD. It felt way more interesting than alcohol and way more safe and you can be much more functional than with alcohol while having a great time.
But the effects are way too long (~8 to 10 hours at low doses) to be a good alcohol replacement at social settings.
I think a key part of freetime2's quoted excerpt is the part that relates to social acceptance.
Right now (well, not exactly now, but tomorrow-now) I can pop into any random over-21 bar near me and buy some drinks for myself and whoever else happens to be around.
And that will be perfectly OK, socially-speaking, according to anyone I'm buying a drink for, and the bartender, and anyone who sees me behave in this fashion.
Even leaving aside such notions as legality and length-of-trip: LSD is a long, long way from reaching that level of social acceptance, don't you think?
That being said, I do wish that psychedelics were more socially accepted as I do think positive outcomes are possible when used in moderation.
I was just saying that a short duration psychedelic could, chemically speaking, be a good replacement for alcohol with pretty much all the benefits without a lot of downsides.
But I agree we are far from there. And there is also the case for the taste of alcoholic beverages.
In this dose range I can feel a little drunk but still have a conversation and be less impaired intellectually than with alcohol.
But it will last longer and, more importantly, I will not be able to sleep for hours which is the biggest blocker at using it at all for those situations.
