New research from Duke University Medical Center in Durham, North Carolina, suggests anxiety may be a major risk factor of problematic marijuana use in early adulthood.
The research, published last month in the Journal of the American Academy of Child and Adolescent Psychiatry, involved 1,229 participants enrolled in the Great Smoky Mountains Study, a 20-year cohort study that followed participants between 1993 and 2015.
The Great Smoky Mountain Study is part of a collaborative effort between Duke University and the North Carolina State Division of Developmental Disabilities, Mental Health and Substance Abuse Services.
One of its primary goals is to estimate the number of youth with emotional and behavioral disorders and the persistence of those disorders over time, according to the study website.
To study risk factors for problematic cannabis use, researchers examined the Great Smoky Mountains participants annually from ages 9 and 16 years and then again at ages 19, 21, 26 and 30 years and logged patterns of problematic cannabis use.
