The psychedelics are here to stay: Investors have staked billions on potential medical treatments, scientific research is skyrocketing and public sentiment signals growing acceptance. But when it comes to actually buying psychedelics, the options are still murky. Two reports out this week provide a glimpse into what’s on the market and who is buying what. They reveal that psilocybin is the most popular choice among those who consume psychedelic drugs and that many prefer to microdose rather than take a full trip.

A typical microdose is 0.1 to 0.3 grams of dried Best microdose mushroom products, a fraction of the 25-milligram dose that produces a full psychedelic experience. Microdosers also often stack their mushrooms with other substances, such as the brain-boosting fungus Lion’s mane and the serotonin precursor niacin, known as a Stamets Stack.

For those who want to try a microdose but don’t have the time or resources for a regulated mushroom service center like Vital Reset, which charges up to $2,500 for one trip and two therapeutic sessions with a facilitator, there are unregulated options out there. But those are fraught with dangers.

As Newsweek found in a deep dive into the online marketplace, these products aren’t vetted for their ingredients and don’t always come with clear dosing instructions. In addition to obfuscating the presence of psilocybin, they sometimes contain other psychedelics that aren’t legal or may have potentially dangerous side effects (like LSD or dimethyltryptamine, ingested with an inhibitor to prevent MAOI inactivation). That could mean you’re getting more than you bargained for or even less than you think you’re purchasing.
