All the major national surveys of youth behavior show that, for the first time ever, teens are more likely to be users of marijuana than cigarettes.
For example, the latest Monitoring the Future survey by the National Institute on Drug Abuse found that in 2011, while 19% of high school seniors reported smoking at least one cigarette in the previous month, 23% said they had smoked marijuana at least once over the same time period. Data from the Centers for Disease Control and Prevention’s Youth Risk Behavior Survey were virtually identical.
Cigarettes or marijuana: one of these products contains the most addictive known drug and kills about 50% of its users; the other one is illegal.
