An incredible, first-of-its-kind trial testing the pain-killing properties of LSD microdoses has delivered the compelling suggestion that tiny, non-psychedelic doses of this infamous drug could serve as an effective analgesic.
Kast’s work was primarily with active psychedelic doses of LSD, and he consistently found the drug produced effective, and protracted, analgesic effects. Unfortunately, Kast’s work with LSD ended, as most psychedelic research did, when access to the drug was restricted in the late 1960s.
Decades later, as the freeze on psychedelic research begins to thaw, the idea of LSD as a pain-reliever still sits on the fringes of psychedelic science. No modern clinical researcher has returned to Kast’s ideas, however, anecdotal cases have begun to emerge highlighting some people self-medicating with LSD microdoses to treat chronic pain.
“From a medical point of view, controlled research on the efficacy of LSD in pain management should focus on non-hallucinogenic, low doses of LSD, which are more manageable and thus preferable over treatment with high doses of LSD that produce full-blown psychedelic effects,” the researchers explain in their paper.
The double-blind, placebo-controlled trial recruited 24 healthy subjects, each of whom took part in four separate experimental sessions, separated by at least five days. Three different LSD microdoses were tested (five, 10, and 20 micrograms) alongside a placebo.
