HARTFORD, Conn. -- Teens who use a lot of marijuana and alcohol are less likely to have a full-time job when they grow up or to get a college education or get married, according to a new study by University of Connecticut researchers.


Young women who were dependent on marijuana and alcohol were also less likely to go to college and had a lower standard of living than non-dependent women, but were equally likely to be employed full time and to get married as non-dependent women.

"This study found that chronic marijuana use in adolescence was negatively associated with achieving important developmental milestones in young adulthood," Elizabeth Harari, a UConn Health psychiatry resident and author of the study, told UConn Today.

Harari presented the results of the research at the American Public Health Association's 2017 Annual Meeting and Expo in Atlanta.

The research tracked information collected by the Collaborative Study on the Genetics of Alcoholism on young people beginning at age 12. These individuals were then re-assessed at two-year intervals until they were between 25 and 34 years old, checking on their educational levels, marital status, full-time employment and social and economic potential.

Earlier academic research has demonstrated that chronic use of alcohol or marijuana in adolescence can affect the user's development. The new UConn study differed in that it attempted to determine what heavy use of pot and booze would mean for a person in adulthood.

"Awareness of marijuana's potentially deleterious effects will be important moving forward, given the current move in the U.S. toward marijuana legalization for medicinal and possibly recreational use," Harari said.
