Image for Uncovering Marijuana Usage Trends in the US

PHI’s Alcohol Research Group and the National Alcohol Research Center, which have conducted several studies on marijuana use, published research in 2017 finding a sharp increase in marijuana use in the U.S., particularly among women, whose rate of use has doubled since 1984. Men’s use declined from the 1980s to 2000 but has since increased to 14.7%, matching earlier rates.

The researchers concluded that the higher usage rates are a reflection of society becoming more tolerant and accepting of marijuana use, rather than a direct result of medicinal or recreational marijuana legalization.
