+ the last time Greenland's ice melted; why Hurricane Debby stalled US Edition - Today's top story: Psilocybin legislation is helping psychedelic drugs make a comeback â a drug researcher explains the challenges they face [View in browser]( US Edition | 7 August 2024 [The Conversation]
[The Conversation]( As a Coloradoan, Iâve had a front-row seat to the fraught controversies surrounding legislation over the use of psilocybin â better known as âmagic mushroomsâ â for medicinal purposes. In November 2022, just days before more than half of Colorado citizens approved Proposition 122 to decriminalize and regulate certain psychedelic plants and fungi, The Denver Post editorial board wrote a strongly worded opinion piece: âThe psilocybin mushroom ballot question â Proposition 122 â goes too far, too fast for Colorado. We urge voters to say âno.ââ Drug researcher Benjamin Y. Fong from Arizona State University explains the [rise of the âpsychedelic renaissanceâ]( and some of the challenges that have arisen in its wake in Colorado and Oregon, including high costs and setting qualifications for providers. Fong describes the burgeoning interest in the supervised use of psilocybin for a range of hard-to-treat health conditions, such as depression and PTSD, and the various state regulations that are under consideration. He notes that activity at the state level will likely inform federal regulations of the nascent drug development industry for psychedelic medicines.
