Gateway effect marijuana risk overblown

  • A research from the University of New Hampshire has revealed that the “gateway effect” of marijuana – that teenagers who use marijuana are more likely to move on to harder illicit drugs as young adults – is overblown.

    According to the research, whether teenagers who smoked pot will use other illicit drugs as young adults has more to do with life factors such as employment status and stress. In fact, the strongest predictor of whether someone would use other illicit drugs is their race/ethnicity, not whether they ever used marijuana.

    The research appeared in the September 2010, issue of the Journal of Health and Social Behavior in the article, “A Life-course Perspective on the ‘Gateway Hypothesis’.” It was conducted by UNH associate professors of sociology Karen Van Gundy and Cesar Rebellon.

    “In light of these findings, we urge U.S. drug control policymakers to consider stress and life-course approaches in their pursuit of solutions to the ‘drug problem,’ ” Van Gundy and Rebellon say.

    Survey data from 1,286 young adults who attended Miami-Dade public schools in the 1990s was used by the researchers. Within the final sample, 26 percent of the respondents are African American, 44 percent are Hispanic, and 30 percent are non-Hispanic white.

    It was found by the researchers that young adults who did not graduate from high school or attend college were more likely to have used marijuana as teenagers and other illicit substances in young adulthood. Moreover, those who used marijuana as teenagers and were unemployed following high school were more likely to use other illicit drugs.

    “Employment in young adulthood can protect people by ‘closing’ the marijuana gateway, so over-criminalizing youth marijuana use might create more serious problems if it interferes with later employment opportunities,” Van Gundy says.
    “While marijuana use may serve as a gateway to other illicit drug use in adolescence, our results indicate that the effect may be short-lived, subsiding by age 21. Interestingly, age emerges as a protective status above and beyond the other life statuses and conditions considered here. We find that respondents ‘age out’ of marijuana’s gateway effect regardless of early teen stress exposure or education, work, or family statuses,” the researchers say.
