Peter Grinspoon, MD, has some advice for clinicians when patients ask questions about microdosing of psychedelics: Keep the lines of communication open — and don’t be judgmental.
“If you’re dismissive or critical or sound like you’re judging them, then the patients just clam up,” said Dr. Grinspoon, a professor of medicine at Harvard Medical School and a primary care physician at Massachusetts General Hospital, both in Boston.
Psychedelic drugs are still illegal in the majority of states despite the growth of public interest in and use of these substances. That growth is evidenced by a flurry of workshops, reports, law enforcement seizures, and pressure by Congressional members for the Food and Drug Administration to approve new psychedelic drugs, just in the past year.
A recent study in JAMA Health Forum showed a nearly 14-fold increase in Google searches — from 7.9 to 105.6 per 10 million nationwide — for the term “microdosing” and related wording, between 2015 and 2023.
Two states — Oregon and Colorado — have decriminalized certain psychedelic drugs and are in various stages of establishing regulations and centers for prospective clients. Almost two dozen localities, like Ann Arbor, Michigan, have decriminalized psychedelic drugs. A handful of states have active legislation to decriminalize use, while others have bills that never made it out of committee.
But no definitive studies have reported that microdosing produces positive mental effects at a higher rate than placebo, according to Dr. Grinspoon. So
“We’re in this renaissance where everybody is idealizing these medications, as opposed to 20 years ago when we were in the war on drugs and everybody was dismissing them,” Dr. Grinspoon said. “The truth is somewhere in between.”
The Science
Microdosing is defined as taking doses of 1/5 to 1/20 of the conventional recreational amount, which might include a dried psilocybin mushroom, lysergic acid diethylamide, or 3,4-methylenedioxymethamphetamine. But even that much may be neither effective nor safe.
Dr. Grinspoon said clinicians should tell patients that psychedelics may cause harm, although the drugs are relatively nontoxic and are not addictive. An illegally obtained psilocybin could cause negative reactions, especially if the drug has been adulterated with other substances and if the actual dose is higher than what was indicated by the seller.
He noted that people have different reactions to psychedelics, just as they have to prescription medications. He cited one example of a woman who microdosed and could not sleep for 2 weeks afterward. Only recently have randomized, double-blinded studies begun on benefits and harms.
Researchers have also begun investigating whether long-term microdosing of psilocybin could lead to valvular heart disease (VHD), said Kevin Yang, MD, a psychiatry resident at the University of California San Diego School of Medicine. A recent review of evidence concluded that microdosing various psychedelics over a period of months can lead to drug-induced VHD.
“It’s extremely important to emphasize with patients that not only do we not know if it works or not, we also don’t really know how safe it is,” Dr. Yang said.
Dr. Yang also said clinicians should consider referring patients to a mental health professional, and especially those that may have expertise in psychedelic therapies.
One of those experts is Rachel Yehuda, PhD, director of the Center for Psychedelic Psychotherapy and Trauma Research at Icahn School of Medicine at Mount Sinai in New York City. She said therapists should be able to assess the patient’s perceived need for microdosing and “invite reflections about why current approaches are falling short.”
“I would also not actively discourage it either but remain curious until both of you have a better understanding of the reasons for seeking this out and potential alternative strategies for obtaining more therapeutic benefits,” she said. “I think it is really important to study the effects of both micro- and macrodosing of psychedelics but not move in advance of the data.”
Navigating Legality
Recent ballot measures in Oregon and Colorado directed the states to develop regulated and licensed psilocybin-assisted therapy centers for legal “trips.” Oregon’s first center was opened in 2023, and Colorado is now developing its own licensing model.
According to the Oregon Health Authority, the centers are not medical facilities, and prescription or referral from a medical professional is not required.
The Oregon Academy of Family Physicians (OAFP) has yet to release guidance to clinicians on how to talk to their patients about these drugs or potential interest in visiting a licensed therapy center.
However, Betsy Boyd-Flynn, executive director of OAFP, said the organization is working on continuing medical education for what the average family physician needs to know if a patient asks about use.
“We suspect that many of our members have interest and want to learn more,” she said.
Dr. Grinspoon said clinicians should talk with patients about legality during these conversations.
“The big question I get is: ‘I really want to try microdosing, but how do I obtain the mushrooms?’ ” he said. “You can’t really as a physician tell them to do anything illegal. So you tell them to be safe, be careful, and to use their judgment.”
Patients who want to pursue microdosing who do not live in Oregon have two legal and safe options, Dr. Grinspoon said: Enroll in a clinical study or find a facility in a state or country — such as Oregon or Jamaica — that offers microdosing with psilocybin.
Clinicians also should warn their patients that the consequences of obtaining illicit psilocybin could exacerbate the mental health stresses they are seeking to alleviate.
“It’s going to get worse if they get tangled up with law enforcement or take something that’s contaminated and they get real sick,” he said.
