This is a challenge to some previous research that has shown that marijuana use is associated with depression and anxiety. The researchers examined the records of nearly 35,000 U.S. adults who participated in the National Epidemiologic Survey on Alcohol and Related Conditions. They examined the prevalence of marijuana use among the study participants in 2001 and 2002 then checked on the participants' rates of mental-health problems in 2004 and 2005. After controlling for a variety of confounding factors, such as socio-demographic characteristics, family history, environment, and past and present psychiatric disorders, the study found that "cannabis use was not associated with increased risk for developing mood or anxiety disorders." But don't break out the celebratory blunt just yet. The study did find an association between marijuana use and later substance-use disorders, such as abuse of and dependence on alcohol, tobacco, marijuana and other drugs. But this isn't necessarily surprising: It's fairly obvious that if you use a substance, you're putting yourself at risk of a substance-use disorder. People who use one drug often use others - think of the classic beer-and-cigarette combo. This is as true of marijuana as it is of, say, alcohol. - --- MAP posted-by: Jay Bergstrom
