“Mind-blowing.” That might be a description you’ve heard in relation to psychedelics like LSD or psilocybin. But in this case, the mind being blown belongs to one of the several researchers who have seen remarkable psychiatric benefits from a single dose of psychedelics. The notion of LSD as medicine was given considerable thought in the 1960s, before the drug went counter-culture and the research largely stopped. Today, the research is back, and the early outcomes have impressed scientists examining the impact of psychedelics on anxiety, depression and other symptoms: “The fact that a drug given once can have such an effect for so long is an unprecedented finding. We have never had anything like it in the psychiatric field.” If future tests go as well, we may be hearing a lot more from Lucy in the Sky with Diamonds (and this time, she’ll have a prescription).
