摘要: Abstract Recent data regarding growth in concurrent use of nicotine and marijuana have raised concern that reductions legal restrictions on may increase risk for tobacco-related harms. Previous studies shown cross-sectional links between both substances, but less is known about associations over time. The goal the present study was to test hypothesis there a bidirectional relationship tobacco products time, such increasing either substance would predict other. Participants (n = 391, 52% male) were 18–24 year-old Californians who non-daily cigarette smokers at enrollment had never been daily smokers. They reported nicotine/tobacco quarterly 2 years. Longitudinal negative binomial logistic regression models indicated each additional timepoint which participants recent predicted 9–11% increases quantity frequency. Additionally, or 19–22% greater Data suggest young adults more frequently are likely exposure, vice versa. These findings need preventive measures focus substances rather than individually.
