I just read "How to Change your Mind" by Michael Pollan. It appears we are inching closer to freeing psychedelic drugs (psilocybin and LSD for example) for medical use via psychedelic therapist. Michael goes over a lot of new research and revisits older research (1950s - 1970s) showing the effectiveness of these drugs when administered by a professional to help cure depression and break addictions to substances like alcohol and nicotine.
