Whether you're a green environmentalist or a doubting "denier." Whether you're convinced of the medical virtues of marijuana or are determined to keep pot illegal. Whatever your perspective on the issues of the day, a defining characteristic of your viewpoint is that it is absolute. Beyond dispute. An analysis of 79 studies on the efficacy of marijuana did not turn out well for medical marijuana advocates. It shows pot provides little help to patients with medical disorders. In many respects, we have forgotten how to put our beliefs to the test of counterarguments and force ourselves to accept the better of the two. This will come as a shock to many of our most earnest issue advocates, but admitting the other side has a reasonable point is a sign of argumentative strength, not weakness. We're talking to you, medical-marijuana advocates. And to you, environmentalists. A recent evaluation of 79 studies involving more than 6,000 patients on the efficacy of marijuana in treating ailments did not turn out well for medical-marijuana advocates. According to the met analysis, medical marijuana appears to be helpful in alleviating muscle pain among sufferers of multiple sclerosis. Other than that, the evidence is thin that pot provides much, if any, help to patients with medical disorders. Yes, we are inviting the very committed supporters of medical marijuana - as well as their ardent kin, marijuana decriminalizers - to come down on our heads for this. But we're only passing along the research we've found. According to the Journal of the American Medical Association, the states that have passed laws approving marijuana for treating conditions such as Alzheimer's, epilepsy and glaucoma did so based on poor-quality studies, patient testimonials and other non-scientific evidence. Likewise with committed, world-changing environmentalists. A University of Chicago study has found that retrofitting your home with efficiency measures may not be quite the energy-saving miracle that advocates claimed it would be. The study examining the economics of installing energy-saving add-ons, including big-ticket items like new windows, rarely made the kind of moneysaving impact they were promised to make. Projected energy savings, according to the study, were 2.5 times greater than real savings. Considering the enormous investment governments, especially the federal government, have put into home improvement energy-saving programs, these findings should be cause for pause. Since 1976, the federal Energy Department has weatherized 7 million homes. In total, the $5,000 average cost of such weatherizing returns an average of $2,400 in savings. That is a huge investment that doesn't seem to come close to penciling out. Neither of these studies constitutes the last word on these issues, of course. But they should, at least, give advocates cause to stop and think. Nothing is ever as perfect as we want it to be. - --- MAP posted-by: Jay Bergstrom
