Marijuana use gender gap widens, mainly among low-income Americans

(Columbia University's Mailman School of Public Health) A new study found that the prevalence of past-year marijuana use increased for both men and women between 2002 and 2014. More men reported past-year use than women, but since 2007, the rate of increase was greater for men than for women, leading to a widening of the gender gap in marijuana use over time. An estimated 6 million additional men and 4 million additional women used marijuana in 2014 compared to 2002.
