In Oregon and Denver, where marijuana is legal for recreational use, activists are now pushing toward a psychedelic frontier: “magic mushrooms.”
Groups in both states are sponsoring ballot measures that would eliminate criminal penalties for possession of the mushrooms whose active ingredient, psilocybin, can cause hallucinations, euphoria and changes in perception. They point to research showing that psilocybin might be helpful for people suffering from depression or anxiety.
“We don’t want individuals to lose their freedom over something that’s natural and has health benefits,” said Kevin Matthews, the campaign director of Denver for Psilocybin, the group working to decriminalize magic mushrooms in Colorado’s capital.
The recent failure of a nationally publicized campaign to decriminalize hallucinogenic mushrooms in California may not portend well for the psilocybin advocates in Oregon and Denver — though their initiatives are more limited than California’s.
The proposal in the Golden State would have decriminalized sales and transportation of magic mushrooms, not just possession. The proposed Denver measure would apply only to that city, while in Oregon mushroom use would be allowed only with the approval of a physician and under the supervision of a registered therapist.
None of the proposed initiatives envisions fully legalizing psilocybin mushrooms, which would allow the government to regulate and tax sales in a similar fashion to medical and recreational marijuana.
In Oregon, advocates face a steep climb to qualify their measure for the ballot, because such statewide initiatives typically require hiring paid signature gatherers, said William Lunch, a political analyst for Oregon Public Broadcasting and a former political science professor at Oregon State University.
Still, familiarity with recreational marijuana may have “softened up” voters and opponents of drug decriminalization, he said. Oregon legalized marijuana for recreational use in 2015, Colorado in 2012.
The Oregon and Denver activists, echoing Lunch, say they hope voters who already accepted pot would now feel comfortable decriminalizing personal use of magic mushrooms as well.
Even so, Paul Hutson, professor of pharmacy at the University of Wisconsin who has conducted psilocybin research, says he is wary of the drive for decriminalization. Psilocybin isn’t safe for some people — particularly those with paranoia or psychosis, he said.
“I reject the idea that that this is a natural progression from medical marijuana,” Hutson said, noting that the safety of pot is much better established. Mushrooms, he added, “are very, very potent medicines that are affecting your mind. In the proper setting, they’re safe, but in an uncontrolled fashion, I have grave concerns.”
Even psilocybin advocates share Hutson’s concerns. “It is such a powerful compound. People should take it very seriously when experimenting,” Matthews said.
These efforts to legitimize hallucinogenic mushrooms come at a time of renewed interest in the potential mental health benefits of psychedelics, including mushrooms, LSD and MDMA (known as ecstasy). Two small studies published in 2016 by researchers from Johns Hopkins University and New York University found that a single large dose of psilocybin, combined with psychotherapy, helped relieve depression and anxiety in cancer patients.
A British company backed by Silicon Valley investor Peter Thiel plans clinical studies in eight European countries to test the use of psilocybin for depression. Other research has examined the effectiveness of psilocybin in treating alcohol and tobacco addiction.
Taking mushrooms can lead to nausea, panic attacks and, rarely, paranoia and psychosis. But they generally are considered safer and less addictive than other illegal street drugs.
