? A study done with 57 patients at the Imperial College of London found that doses of capsulated cannabis extract reduced post-operative pain. Doses of five, 10 and 15mg THC were used, and the level of pain relief was shown to be dose-related. A follow-up study is being done with 400 patients, to test a 10mg THC extract.

? A study done with 40 cancer patients at the Lukas Clinic, in Arlesheim, Switzerland, found that capsulated cannabis extracts produced an increase in appetite and pain relief as well as a reduction in nausea.
