• I awoke from The Sickness at the age of forty-five, calm and sane, and in reasonably good health except for a weakened liver and the look of borrowed flesh common to all who survive The Sickness... When I speak of drug addiction I do not refer to keif, marijuana or any preparation of hashish, mescaline, Banisteriopsis caapi, LSD6, Sacred Mushrooms or any other drugs of the hallucinogen group... There is no evidence that the use of any hallucinogen results in physical dependence.
