The reason: It's not your parents' marijuana. A 25 percent increase in serious problems with marijuana from 1992 to 2002 is likely explained by a 66 percent increase in the potency of the drug, researchers from the National Institute of Drug Abuse report in today's Journal of the American Medical Association. Marijuana today has nearly five times the level of THC, the drug's most active ingredient, than was in the pot of the 1970s, government figures suggest. Marijuana has become so strong that the liberal government of the Netherlands is considering classifying it as a "hard" drug to be banned from the "coffee shops" of Amsterdam, where it is sold openly. Hydroponic growing techniques and the selective use of seeds from powerful strains contribute to the higher levels of THC, researchers say. Superstrong "BC Bud" from British Columbia can easily be obtained, especially in the northwest United States. "People still have a naive approach to marijuana and think of it as a harmless substance," said Dr. William Compton, lead author of the new study and an epidemiologist with the National Institute of Drug Abuse, one of the National Institutes of Health. "It's not as innocent as they might expect." About 4 percent of Americans age 18 and older say they smoked marijuana in the past year, the same as a decade ago, the study found. But use of the drug among blacks and Hispanics increased significantly, with use among blacks now surpassing that by whites. Rates of abuse and addiction increased the most among minorities, with serious marijuana problems now more common among blacks and Hispanics than in whites. Overall, more than a third of marijuana users report signs of abuse or addiction. The study is based on two sets of information gathered in interviews by the U.S. Census Bureau. Marijuana users who acknowledged at least one of four criteria for abuse, such as pot-related legal problems or interference with work, were considered abusers. Those who noted at least three of six other criteria -- including the need to use more pot to achieve the same effect and unsuccessful attempts to cut back -- were categorized as dependent, or addicted. "This study shows that there is a certain propensity to addiction for marijuana," Compton said. "That may surprise people, that marijuana can be addictive." - --- MAP posted-by: Richard Lake
