This issue continues to bubble up in political discussions, so it's important that associated policy decisions be based on facts. Research continues to identify significant consequences to recreational marijuana use. The Democratic nominee for U.S. Senate, state Sen. Connie Johnson of Oklahoma City, supports decriminalizing marijuana use. She defended that stance in the debate. Her opponent, U.S. Rep. James Lankford, R-Oklahoma City, isn't a fan of that idea. "I just have a hard time with anyone saying, 'The best thing we can do for our kids is to get their parents to smoke more marijuana,' " Lankford said. That's a common-sense conclusion validated by credible research. Wayne Hall, of The University of Queensland Centre for Youth Substance Abuse Research, recently completed a review of research on marijuana use over the past two decades. On the whole, he found credible studies consistently show "that cannabis use increases the risk of accidents and can produce dependence, and that there are consistent associations between regular cannabis use and poor psychosocial outcomes and mental health in adulthood." "Research in the past 20 years has shown that driving while cannabis-impaired approximately doubles car crash risk and that around one in 10 regular cannabis users develop dependence," Hall writes. "Regular cannabis use in adolescence approximately doubles the risks of early school-leaving and of cognitive impairment and psychoses in adulthood. Regular cannabis use in adolescence is also associated strongly with the use of other illicit drugs." Among middle-aged adults, regular marijuana use "probably increases cardiovascular disease risk" while marijuana's "effects on respiratory function and respiratory cancer remain unclear, because most cannabis smokers have smoked or still smoke tobacco." One study reviewed by Hall found cannabis users "had higher rates of hospitalization for injury from all causes than former cannabis users or nonusers" among 64,657 patients from a Health Maintenance Organization. A review of nine studies found "recent cannabis use" doubled the risk of a car crash. Those driving while high are less of a threat than drunk drivers, but Hall notes marijuana use still accounted for 2.5 percent of traffic deaths in France. That the push for marijuana legalization coincides with public anti-tobacco efforts is an often-noted irony. Hall's findings suggest marijuana legalization would undermine those anti-smoking efforts. He notes that in 1993, kids tended to smoke cigarettes and then move on to marijuana. But thanks to subsequent anti-smoking efforts, "cannabis smoking is initiated increasingly by young people who have not smoked tobacco. A number of recent studies have reported that these cannabis smokers are now more likely to become tobacco smokers after using cannabis, a pattern described as a 'reverse gateway.' " Supporters of legalization will undoubtedly argue that marijuana shouldn't be available to teenagers. Yet legalization is likely to increase availability to underage users, not decrease it. There's also little doubt marijuana's effects are less adverse than some drugs, such as opiates, and that the legality of alcohol produces negative outcomes that often exceed those associated with marijuana. But the question isn't whether there are worse drugs than marijuana. The question is whether there is good reason to legalize, and therefore tacitly condone, widespread marijuana use. Hall's research demonstrates why so many citizens continue to give the same answer to that question: No. - --- MAP posted-by: Jay Bergstrom
