"I think it's interesting that so many clinical trials are necessary before a prescription can be signed for medicinal marijuana, because there are many drugs that are being used that have never passed double-blind placebo controlled studies," Conyette told the Brandon Sun. "Why would medicinal marijuana be singled out, when 80 per cent of many hospital procedures have never been studied with double-blind, placebo controlled tests?"
Slightly off-topic, but related in a way because of the mention of double blind.
