Voters in 16 cities and unincorporated Clackamas County, Oregon, have opted to ban the regulated sales and use of psilocybin mushrooms, with voting results showing support for bans ranging from 55% to 70%. Communities such as Brookings, Redmond, and Oregon City have enacted bans on licensed psilocybin businesses, with Redmond also imposing a two-year moratorium. This election comes four years after Measure 109 legalized psilocybin in Oregon, allowing for licensed service providers to administer the substance. Meanwhile, Massachusetts voters rejected a similar legalization measure for psilocybin. Despite initial support for psilocybin therapy for issues like anxiety and depression, the recent voting reflects a significant backlash against its commercialization in Oregon. Notably, a ban in the small community of Nehalem is still undecided, with the measure failing by just three votes.
