Joe Schrank got the call six years ago that his friend Greg Giraldo had been found unconscious after an overdose in a New Jersey hotel room. Schrank had tried in vain to save him. Using pot instead of cocaine and Valium was something Schrank had suggested to his friend weeks before his death. Although it is an unpopular idea in the rehab world, where Schrank had made his career, he nonetheless had a hunch marijuana could have helped his friend. After Giraldo’s death, Schrank began working with Bienenfeld on treatment plans that incorporated marijuana as a crucial detox step. He also connected with Amanda Reiman, former head of marijuana law and policy at the Drug Policy Alliance, whose research at University of California, Berkeley, for more than a decade has focused on the use of cannabis as a viable substitute for prescription drugs. Schrank took another step and opened High Sobriety – a first-of-its-kind rehab center that uses cannabis as a central part of its treatment plan. Seen as a highly contentious move in the rehab world, High Sobriety has been met with skepticism and criticism for its use of marijuana in a field where success is traditionally measured by total abstinence.
