John Hopkins Finds Optimum Beneficial Dose for Therapy

The latest Psilocybin study at the Johns Hopkins University School of Medicine set out to discover the "sweet spot" dose of pure chemical Psilocybin that would offer users all the positive benefits while minimizing the negative effects. Researchers screened volunteers between the ages of 29 and 62, ensuring that they were of sound mind and body (as the saying goes), and chose 18 to undergo five sessions lasting eight hours each and timed a month apart. At four of these, the volunteers would receive varying doses of the chemical and a placebo (no drug) at the remaining session.
In common with other studies at Hopkins, volunteers in this one were settled into a comfy couch in an aesthetically-pleasing, living-room-like environment during each session and were accompanied by trained monitors. The subjects were encouraged to lie back and relax, with mood-complementing classical and world music being played through headphones. Neither the volunteers or the monitors knew beforehand how much Psilocybin they were to receive at each session but subjects were given preparatory guidance and coaching.
Perhaps unsurprisingly, researchers noted that the reported positive effects increased as higher doses were given, but also that there was a sharp increase in the negative aspects at the very highest dose. At the highest dose (30 mg/70 kg, p.o. - meaning "per oral" or by mouth), 78 percent of the volunteers were reporting one of the top five most spiritually significant happenings of their lives but those suffering anxiety, stress and fear episodes increased by six times, so that around a third of those participating in the study showed signs of psychological struggle.
By contrast, only one of the volunteers receiving the second highest dose (20mg/70 kg, p.o.) reported having negative issues, and all benefited from positive experiences, although with less intensity than at the highest dose. Critically, even the lowest amount used in the study resulted in notable and long-lasting positive changes in the attitudes, behavior, overall satisfaction and spiritual beliefs of the subjects during the period of study. These changes were also noticed by family members and friends.
"We seem to have found levels of the substance and particular conditions for its use that give a high probability of a profound and beneficial experience, a low enough probability of psychological struggle, and very little risk of any actual harm," says lead author of the study, Roland Griffiths, Ph.D.
Those who received a small taster before a higher dose were observed as being even more likely to reap the benefits than those who were only given the higher dose.
A month after the conclusion of the study, 61 percent rated the experience as being the single most important spiritual experience of their lives and 14 months later, 94 percent of the volunteers rated it in their top five.
