The Psilocybin Service Initiative of Oregon is expected to appear on the 2020 general election ballot.
(If you want to know more about psilocybin, read Michael Pollan’s 2018 book, “How to change your mind.” See also books about LSD microdosing (e.g. Ayelet Waldman’s 2017 “A really good day.”) Compare with Jill Bolte Taylor’s 2006 book (and her TED talk), “My Stroke of Insight,” and her description of how the world looked from her right brain (while her left brain was incapacitated due to a massive stroke.) There is also the Psilocybin Wikipedia page and the Denver, CO, psilocybin ballot measure.)
You can also read the full text of the Psilocybin Service Initiative of Oregon LC (legislative concept) at the Initiatives, Referendums and Referrals database (from the Oregon Secretary of State, Voting and Election website).
