This mantra is being repeated constantly by opponents to its clinical use who are not challenged to explain what they mean by a "lack of evidence." While I would agree you can never have enough scientific evidence to support the safety and efficacy of any medical treatment, it is disingenuous to hide one's opposition to the medical use of marijuana behind claims that it hasn't undergone the same testing and approval process as the pharmaceutical industry's new products, something which is never likely to happen because the source material isn't patentable and thus there is little motivation for industry to incur the expense. Interested readers should go to Health Canada's website on the medical use of marijuana, where there is an extensive review of the literature on this topic, including reference to a thousand peer-reviewed publications addressing the issues of clinical utility, dosage, risk, benefit, efficacy and safety. A little better balance when editorializing on this issue would seem fair and reasonable. Desmond Colohan, MD, Charlottetown - --- MAP posted-by: Jay Bergstrom
