Denver Decriminalizes Magic Mushroom Possession – Are They Dangerous?

In a narrow vote, Denver voters approved a change that decriminalizes possession of psilocybin mushrooms, also known as magic mushrooms.

When the change is fully implemented, Denver will not be able to prosecute or arrest those over the age of 21 who possess the drug.1

So, why did 50.56% of Denver voters approve possession of shrooms? Unlike other drugs, there is not a wealth of research surrounding hallucinogens like “shrooms.” This leads many people to believe that the drugs are safe, but that’s not the entire truth. While magic mushrooms containing psilocybin are not as addictive as other substances such as opiates, the danger of addiction is still present as tolerances build. Worse yet, the shrooms can create negative side effects when users are under the influence and having a “trip.”

The Dangers of Magic Mushrooms

With the recent shift of psilocybin in Denver, we want to reinforce the possible dangers of hallucinogens, like psilocybin. Many people feel that these drugs are medicinal or even spiritual, but their unpredictability means that each experience is different, and things can turn south quickly.

Magic mushrooms achieve hallucinogenic effects through the active chemical psilocybin, which converts to psilocyn in the body. The chemical activates serotonin receptors in the brain, especially the prefrontal cortex, which is a brain region responsible for perception, mood, and cognition.2 The problem is that the drugs act differently within different people, and negative effects can and do often occur. Negative effects of shrooms include:

  • Distorted thinking
  • Vomiting
  • Terrifying hallucinations
  • Muscle weakness
  • Paranoia
  • Confusion
  • Psychosis

Frightening or terrifying hallucinations can last throughout the entire high, resulting in short-term and even long-term psychosis induced by psilocybin. Existing mental health problems can surface or are exacerbated by ingesting magic mushrooms.2

Though Denver voters have chosen to allow possession of shrooms for those over the age of 21, hallucinogenic drugs still carry dangers. Contact our Florida drug detox center for more guidance on the dangers of these drugs, along with support for getting sober.
