Thanks! A quick Google search and you can find the Brooklyn Psychedelic Society (I also linked to their group in my article). You can find them on meetup dot com as well. Yes, psilocybin is not legal or decriminalized here yet, but it seems finding micro doses has become easier with the rise of the psychedelic renaissance and word of it spreading via social media (just be careful you don't fall for a scam seller). As of the last Brooklyn Psychedelic Society event I attended about two weeks ago, they were still finalizing the bylaws for the psychedelic co-ops, but I am very hopeful they will come into fruition. I believe you can sign up for the BPS mailing list and stay up-to-date with their events that way!
