| POT STUDY AS 'JUNK SCIENCE' The results of Dr. Murray Mittleman's study linking marijuana and heart attacks are hardly newsworthy ["Pot raises heart attack risk, study says," June 14]. The flaws are readily apparent to anyone with a basic understanding of research methods. The sample size is statistically insignificant, no casual relationship has been established, and the study itself has never been replicated. Out of 3,882 patients who had heart attacks, 124 were current cannabis smokers and nine had smoked within an hour of their heart attack. Based on this minuscule, self-selected sample, Dr. Mittleman concludes that the risk of a heart attack is 4.8 times higher after smoking cannabis. Assuming the Dr. Mittleman's conclusions are accurate, the fact that heart attack risk for an otherwise healthy 50-year-old man is about 10 in 1 million highlights the sensationalism of the widespread publicity the study is receiving. Such junk science is routinely funded by the United States government and well-publicized. Millions have been
spent trying to find harm in a relatively harmless plant.
Regardless of whether or not the study in question is
ever replicated and subjected to peer review, the results
will no doubt be repeated by drug warriors for decades. Despite a relatively
brief period on the market, the blatantly recreational
drug Viagra has already killed more people than
marijuana, a relatively harmless drug compared to toxic
alcohol and highly addictive tobacco. So much for protecting
the children from drugs. One need only follow the money
trail to find out why a given policy exists. |
