New research presented May 5, at the Pediatric Academic Societies (PAS) annual meeting here supports the theory that cigarettes are a gateway drug to marijuana.
"Contrary to what we would expect, we also found that students who smoked both tobacco and marijuana were more likely to smoke more tobacco than those who smoked only tobacco," said study author Megan Moreno, an investigator at Seattle Children's Research Institute and associate professor of pediatrics at the University of Washington.
Moreno and her colleagues randomly selected incoming college students from two universities, one in the Northwest and one in the Midwest to participate in the longitudinal study.
Students were interviewed prior to entering college and again at the end of their freshman year regarding their attitudes, intentions and experiences with substances, reports Science Daily.
Specifically, students were asked if they had used tobacco or marijuana ever in their lives and in the past 28 days. Researchers also assessed the quantity and frequency of marijuana and tobacco use in the past 28 days.
