Scientists at Johns Hopkins studying psilocybin (the active ingredient in hallucinogenic "magic mushrooms") say they've figured out the dosage "sweet spot"—the "mama bear" dose at which a hypothetically adventurous Goldilocks would say "just right, man."
We've known for a while know that shrooms can be effective at treating anxiety and depression. But finding the proper dosage—high enough to produce a "transformative experience" with long-lasting beneficial effects, but low enough to prevent bad trips—is key for the possibility of using mushrooms in a clinical setting.
Alas, the study's press release doesn't specify what, exactly, that sweet spot is, except to say it was the second-highest dosage taken. But the study did find that 94 percent of participants described their mushroom trips as "one of the top five most spiritually significant experiences of their lifetimes," and 89 percent told researchers that they'd noticed "lasting, positive changes in their behavior."
