Voters in Denver, Colorado, made their city the first in the U.S. to decriminalize psychedelic mushrooms by approving a ballot measure on the issue. Its provisions prohibit the city government from using any resources to impose criminal penalties against adults over 21 years of age for personal use and possession of psilocybin, the active ingredient in so-called "magic mushrooms." Initiative 301 also specifies that going after people for the mushrooms is the city's “lowest law enforcement priority” and establishes a review panel to assess and report on the effects of the change by early 2021. The new ordinance is just one example of how drug policy reform activists are increasingly setting their sights beyond marijuana.
