Abstract: Objectives: We investigated the 3-year follow up on cannabis use disorder (CUD) of cannabis users with different use patterns, as defined by Lower Risk Cannabis Use Guidelines. Methods: Data was obtained from the US surveys NESARC wave 1 (2001-2002) and wave 2 (2004-2005), which included 31,464 respondents with no history of CUD at wave 1. We applied multiple logistic regression and propensity score method to examine the 3-year risk of DSM-IV CUD among different use patterns. The risk of transitioning to higher use frequency was also accessed. Results: Propensity score method showed significant association between lower risk cannabis use and CUD, but not increased use frequency. A significant increase in the risk of CUD was also observed among higher risk cannabis users. Logistic regression showed similar results. Conclusions: The findings suggest that guideline recommended lower risk use pattern may not completely protect an individual from developing CUD.
