Earlier today, the National Institute on Alcohol and Alcoholism (NIAAA) released the results of a study claiming that twice as many adults use marijuana now as they did ten years ago. Overall, the study concluded that nine percent of the population of the United States has used marijuana in the past year. According to the survey, about a fifth of people in their 20s have used marijuana in the past year.

The study derived its conclusions from the results of a pair of surveys conducted by the NIAAA's National Epidemiologic Survey on Alcohol and Related Conditions. "In total," the NIAAA says, "79,000 people were interviewed on alcohol use, drug use and related psychiatric conditions during the 2001-2002 and 2012-2013 surveys."

Of course, the pair of surveys the NIAAA is basing their findings on technically show the number of people who were willing to admit that they smoked weed ten years ago vs. the number of people who are willing to admit that they smoke weed now. In other words, the results of the NIAAA's survey might reflect less of an increase in actual marijuana use among Americans and instead reflect changing societal attitudes regarding use of the drug.
