A 22-day hospital stint for multiorgan failure definitely constituted a ‘bad trip’ for a man who injected himself with magic mushrooms that later began growing in his blood.

Spilling the tea in the Journal of the Academy of Consultation-Liaison Psychiatry, doctors revealed the 30-year-old had been inspired by the therapeutic benefits of psychedelic microdosing and attempted to self-treat his opioid dependence and depression.

But the patient — referred to as Mr X — took an unconventional route, boiling down psilocybin mushrooms in water before filtering the solution through a cotton swab to make what he called “mushroom tea”.

He then self-administered the concoction intravenously.
