Psilocybin, a mind-altering chemical found in “magic mushrooms,” once again proves the most powerful treatment yet for anxiety and depression, this time in cancer patients.
Two parallel studies have demonstrated remarkable effects from the drug, one which also also been shown in other studies to be the most potent pharmacological treatment ever found for alleviating major depression [here, here and here], social isolation, and spousal abuse, as well as in reducing tobacco smoking.
Gee, guess those ‘shrooms really are magic.
We include reports on both of the latest studies, first from the New York University Langone Medical Center:
When combined with psychological counseling, a single dose of a mind-altering compound contained in psychedelic mushrooms significantly lessens mental anguish in distressed cancer patients for months at a time, according to results of a clinical trial led by researchers at NYU Langone Medical Center.
Published in the Journal of Psychopharmacology [access free for the article] online December 1, the study showed that one-time treatment with the hallucinogenic drug psilocybin—whose use required federal waivers because it is a banned substance—quickly brought relief from distress that then lasted for more than 6 months in 80 percent of the 29 study subjects monitored, based on clinical evaluation scores for anxiety and depression.
The NYU Langone-led study was published side by side with a similar study from Johns Hopkins University. Study results were also endorsed in 11 accompanying editorials from leading experts in psychiatry, addiction, and palliative care.
“Our results represent the strongest evidence to date of a clinical benefit from psilocybin therapy, with the potential to transform care for patients with cancer-related psychological distress,” says study lead investigator Stephen Ross, MD, director of substance abuse services in the Department of Psychiatry at NYU Langone.
“If larger clinical trials prove successful, then we could ultimately have available a safe, effective, and inexpensive medication—dispensed under strict control—to alleviate the distress that increases suicide rates among cancer patients,” says Ross, also an associate professor of psychiatry at NYU School of Medicine.
Study co-investigator Jeffrey Guss, MD, a clinical assistant professor of psychiatry at NYU Langone, notes that psilocybin has been studied for decades and has an established safety profile. Study participants, he says, experienced no serious negative effects, such as hospitalization or more serious mental health conditions.
Although the neurological benefits of psilocybin are not completely understood, it has been proven to activate parts of the brain also impacted by the signaling chemical serotonin, which is known to control mood and anxiety. Serotonin imbalances have also been linked to depression.
For the study, half of the participants were randomly assigned to receive a 0.3 milligrams per kilogram dose of psilocybin while the rest received a vitamin placebo of 250 milligrams of niacin, known to produce a “rush” that mimics a hallucinogenic drug experience.
Approximately halfway through the study’s monitoring period (after seven weeks), all participants switched treatments. Those who initially received psilocybin took a single dose of placebo, and those who first took niacin, then received psilocybin. Neither patients nor researchers knew who had first received psilocybin or placebo. Guss says, “The randomization, placebo control, and double-blind procedures maximized the validity of the study results.”
One of the key findings was that improvements in clinical evaluation scores for anxiety and depression lasted for the remainder of the study’s extended monitoring period—specifically, eight months for those who took psilocybin first.
