Page: A8 FACT AND FICTION ON MEDICAL POT One of the key arguments used by opponents of legalizing medical marijuana in Florida should be put to rest. A study recently published in The Lancet Psychiatry concludes that medical marijuana laws do not increase use of marijuana by teenagers. As the supporters of medical marijuana prepare for another campaign for a constitutional amendment, this important study should reduce the overheated rhetoric and ease some public concerns. To be sure, heavy pot use can cause physical and psychological dangers in youths whose brains and personalities are still forming. And the National Institute of Drug Abuse has long known that states with medical marijuana laws have higher rates of adolescent marijuana use than other states. The important question was why. The Lancet study, financed by NIDA and based on 23 years of surveys of 8th, 10th and 12th graders, found that states such as California, Colorado and Oregon had high marijuana usage by teens before passing medical marijuana laws. But after the laws went into effect, usage did not rise relative to other states. The findings 'suggest that the debate over the role of medical marijuana in adolescent marijuana use should cease," the authors state, and 'resources should be applied to identifying the factors that do affect risk." Those are strong words from researchers whose previous work has been wrongfully quoted by antipot activists as evidence that medical marijuana leads to higher teen use. Trend lines of adolescent marijuana use go up and down, with little understanding of cause. After medical marijuana systems came on line in the late 1990s, teen usage dropped steadily in all states. Then smoking picked up in the mid 2000s, with medical marijuana critics contending that the rise was a delayed reaction to states legally acknowledging that marijuana has acceptable uses. That theory has grown increasingly untenable, though, because adolescent usage now appears to be declining again, even as more states pass medical marijuana systems. The Lancet study, the most thorough of its kind, should put the issue to rest. Within a few months, Florida will venture into a limited medical marijuana system when five growers can start selling a noneuphoric stain of cannabis to people with epilepsy, cancer and a few other ailments. A proposed constitutional amendment that will likely go to voters next year would institute a much broader system - allowing use of all marijuana strains and expanding availability to people with chronic pain and other diagnoses. Under either system the Department of Health should develop rules, such as requiring clear labeling on edible products that sometimes mimic sweets in other states, to protect children and young people from unintended repercussions. Dispensaries also should be required to maintain strict inventory control to avoid diversion to a black market that already makes marijuana readily accessible to adolescents. State and local authorities should not become complacent about marijuana's potential for ruining young lives. Education, counseling and rehabilitation programs should receive the attention and funding they deserve. As for medical marijuana, however, the Lancet study confirms that Florida should be able to find workable ways to bring relief to sick adults without endangering vulnerable adolescents. - --- MAP posted-by: Jay Bergstrom
