High School Seniors as Likely to Smoke Marijuana as Cigarettes

According to data culled by the Center for Substance Abuse Research (CESAR) from the University of Michigan's ongoing Monitoring the Future study, high school seniors are now about as likely to smoke marijuana as cigarettes: 19.4% reported using marijuana in the last 30 days, vs. the 20.4% lof seniors who reported smoking cigarettes. 
Both cigarette use and marijuana use by seniors have been declining since 1997 -- but cigarette use has dropped much more quickly. 
This is the first time since the early 1980s that cigarette and marijuana use have paralleled each other so closely. (Click on the image for a closer look at the numbers.)
