From many sectors I am reading there needs to be more longterm studies about the effects of long term marijuana use. Even with drugs that have been researched by pharmaceutical companies and been prescribed by doctors for years, untoward side effects have occurred later, such as in the case of Thalidomide and Valium, which was found to be seriously addictive. Also there is Chlorpromazine in the "'60s, which turned the faces of many patients purple, permanently, if they went outside in bright sunlight for hours, and caused tardive dyskenesias, which is, in part, involuntary facial grimacing and twitching, and shuffling gait. Dr. Donald Tashkin, of UCLA found in his 30 year studies of 450 subjects that there is more chronic bronchitis among regular marijuana smokers than among regular tobacco smokers, even though the tobacco smokers smoked, of course, many more cigarettes per day. When lungs were examined, it was found that four times more tar was left by marijuana than by the same amount of tobacco smoked. In studies of marijuana use for medical purposes, there is evidence that it decreases immunity in just those patients who need their immunities most. Madeline Bruce Nanaimo - --- MAP posted-by: Jo-D
