In the summer of 1986, the DEA administrator initiated public hearings on cannabis rescheduling. The hearings lasted two years, involving many witnesses and thousands of pages of documentation. On September 6, 1988, DEA Chief Administrative Law Judge Francis L. Young ruled that cannabis did not meet the legal criteria of a Schedule I prohibited drug and should be reclassified. He declared that cannabis in its natural form is "one of the safest therapeutically active substances known to man. (T)he provisions of the (Controlled Substances) Act permit and require the transfer of marijuana from Schedule I to Schedule II".
