"Controlled evidence does not support the view that THC or smoked marijuana offer clinically effective analgesia (pain killer) without causing significant adverse events."   American Medical Association, Report of the Council on Scientific Affairs, 10-1-97, Conclusions

Aside from the Conclusions section, this report addresses the use of marijuana and dronabinol in treatment of neuropathic pain on pages 14, 15. (Report of the Council on Scientific Affairs)

"No clinical trials involving smoked marijuana have been performed in patients with naturally occurring pain. Two adequate and well-controlled studies in cancer pain compared graded doses of oral THC to placebo, and one of these included graded doses of codeine as a control. Although there was evidence of analgesic efficacy, the studies indicate there is a narrow therapeutic margin between the doses that produce useful analgesia and those producing unacceptable adverse CNS effects."    National Institute of Health Report, page 3

A two-day scientific meeting "Workshop on the Medical Utility of Marijuana" was held on February 19-20, 1997 to "review the scientific data concerning the potential therapeutic uses for marijuana and the need for and feasibility of additional research." The report from this workshop addresses the use of marijuana and dronabinol as an analgesia on pages 3, 16, and 17. (National Institute of Health (NIH) Summary)
