As of my last update in January 2022, psychedelic mushrooms, also known as psilocybin mushrooms, are not legal for recreational or medicinal use in Colorado. However, there have been significant developments in the decriminalization and legalization efforts surrounding psychedelics in the state.

In May 2019, the city of Denver made history by becoming the first city in the United States to effectively decriminalize psilocybin mushrooms. This initiative, known as Initiative 301, made the personal use, possession, and cultivation of psilocybin mushrooms for adults 21 and older the city’s lowest law enforcement priority. It also prohibited the city from spending resources to impose criminal penalties for these activities.

Following Denver’s lead, other cities and municipalities in Colorado have considered similar measures to decriminalize psychedelics. In November 2020, the city of Aurora passed a resolution supporting further research into the therapeutic benefits of psychedelic substances, including psilocybin mushrooms.

Moreover, in November 2020, Oregon became the first state in the United States to legalize psilocybin therapy for mental health treatment in supervised settings. While this development does not directly impact Colorado’s laws, it reflects a growing trend of changing attitudes and policies towards psychedelics nationwide.

Despite these developments, it’s essential to note that psilocybin mushrooms remain illegal at the federal level in the United States, classified as Schedule I substances under the Controlled Substances Act. This classification means that they are considered to have a high potential for abuse and no accepted medical use, making possession, distribution, and cultivation illegal under federal law.

In summary, while psychedelic mushrooms are not legal for recreational or medicinal use in Colorado, there have been significant strides in decriminalization efforts, particularly at the local level. However, individuals should be aware of the legal risks associated with possessing, using, or cultivating psilocybin mushrooms and stay informed about any changes in state and federal laws.
