Who is Roland Griffiths and how did his study address the confounds of the Pahnke experiment?
Answer: Roland Griffiths is a Johns Hopkins University scientist and proponent of resuming the pharmacological research of hallucinogenics. He is the lead author of a rigorous test of the acute and long-term effects of psilocybin in adults, and his subjects reported an acute increase in mystical experience and a substantial personal and spiritual experience, with sustained positive changes in attitudes, mood and behavior. His study is one of the few recent research studies of hallucinogens, and his findings replicate the findings of the Pahnke experiment.
