Absolutely not Stoned...Just Beautiful
There is a link between Bill's LSD and niacin (vitamin B3) experiences:
British radio commentator Gerald Heard introduced Bill W to Aldous Huxley and British psychiatrists Humphrey Osmond and Abram Hoffer (the founders of orthomolecular psychiatry). Humphrey and Osmond were working with schizophrenic and alcoholic patients at a Canadian hospital.
Bill joined with Heard and Huxley and first took LSD in CA on August 29, 1956. Medically supervised by psychiatrist Sidney Cohen of the LA VA hospital, the LSD experiments occurred well prior to the "hippie era" of the late 1960's.
At the time, LSD was thought to have psychotherapeutic potential (research was also being funded by the National Institutes of Health and National Academy of Sciences). The intent of Osmond and Hoffer was to induce an experience similar to the DTs in hopes that it might shock alcoholics away from alcohol.
Among those invited to experiment with LSD (and who accepted) were Nell Wing, Father Ed Dowling, Sam Shoemaker and Lois Wilson. Marty M and other AA members participated in NY (under medical supervision by a psychiatrist from Roosevelt Hospital).
Bill had several experiments with LSD up to 1959 (perhaps into the early 1960's). The book "Pass It On" (PIO 368-377) reports the full LSD story and notes that there were repercussions within AA over these activities. Lois was a reluctant participant and claimed to have had no response to the chemical.
