(Columbia University's Mailman School of Public Health) A new study by researchers at Columbia University's Mailman School of Public Health found that the prevalence of past-month marijuana use among reproductive-aged women rose from 2.4 percent in 2002 to 3.9 percent in 2014, an increase of 62 percent. Past-month marijuana use was highest among those ages 18 to 25 years, reaching 7.5 percent in 2014, and significantly higher among those ages 26 to 44 years (2 percent).
