Survey on the medical use of cannabis 

Survey on the medical use of cannabis

From April 1998 to April 1999, the Association for Cannabis as Medicine (Cologne), in cooperation with the Institute for Oncological and Immunological Research, conducted an anonymous standardized survey on the medical use of cannabis and cannabis products by patients in Germany, Austria and Switzerland (Schnelle, Grotenhermen, Reif, & Gorter, 1999). Throughout about one year, 170 subjects participated in this survey; questionnaires administered to 128 of these patients were included in the evaluation. The most frequently mentioned indications for medicinal cannabis use were depression (12%), multiple sclerosis (11%), HIVinfection (9%), migraine (7%), asthma (6%), back pain (5%), hepatitis C (5%), sleeping disorders (5%), epilepsy, spasticity, headache, alcoholism, glaucoma, nausea, disk prolapse, and spinal cord injury. The majority of patients used natural cannabis products.
