Robert Benvenuti, the most vocal opponent of the medical marijuana legalization bills in the Kentucky Legislature, is not the only one concerned about the growing acceptance of what is still considered a Schedule I drug under federal law. Benvenuti has called for more research on cannabis use, a sentiment echoed last week by Francis Collins, the director of the National Institutes of Health. Collins' comments were regarding the legalization of marijuana in general, not just for medicinal purposes. "I'm afraid I'm sounding like this is an evil drug that's going to ruin our civilization and I don't really think that," he told USA TODAY. "But there are aspects of this that probably should be looked at more closely than some of the legalization experts are willing to admit." One study could examine if there are any links between marijuana and lung cancer, for example, he said. The NIH in December released a survey showing that more than 60 percent of 12th-graders do not view marijuana use as harmful, a rate that has risen in the past two decades. More than before, 6.5 percent, said they smoked marijuana daily. "This is not just an issue of increased daily use," Dr. Nora D. Volkow, the director of the National Institute on Drug Abuse, said when the survey results were released. "It is important to remember that over the past two decades, levels of THC - the main psychoactive ingredient in marijuana - have gone up a great deal. ... Daily use today can have stronger effects on a developing teen brain than it did 10 or 20 years ago." THC, or tetrahydrocannabinol, levels went up from 3.75 percent in 1995 to 15 percent in an average marijuana cigarette, she said. The national organization Smart Approaches to Marijuana, which says it seeks "a middle road between incarceration and legalization," cites studies that say marijuana use affects parts of the brain used for memory, learning, attention and reaction time. Other health harms from marijuana, its members say, are an increased risk of heart attack and lung irritation, and a link with mental illness. Despite polls showing that a majority of Kentuckians favor use of medical marijuana with a doctor's recommendation, just 26 percent favored the use of marijuana for recreational purposes, according to a Kentucky Health Issues Poll released in May 2013. Benvenuti, at Thursday's House Health and Welfare Committee meeting, said a study showed that traffic fatalities in Colorado had increased 114 percent under its medicinal marijuana law. The study, published in January in the American Journal of Epidemiology, showed that the presence of marijuana in drivers had increased by 8 percent over the past decade, although the study did not say marijuana use was the cause of the crashes. The drug also could be detected in a blood up to a week after use, the study's authors said. Colorado highway patrol data shows that traffic fatalities there declined each year from 2007-11. The state passed its medical marijuana law in 2000. Benvenuti's biggest cause for concern was that little research exists for possible benefits of marijuana. That's especially true on the federal level, because getting the drug approved for use in a study can be difficult. "Representative (Mary Lou) Marzian said marijuana 'could possibly' help some people - 'could possibly' - and does not hurt anybody," he said. "What FDA-approved research has been done to show that it can help people? Because we don't approve drugs in this country based on 'could possibly.' " - --- MAP posted-by: Jay Bergstrom
