Research Note: Cigarette Smoking Quit Ratios Among Adults in the USA With Cannabis Use and Cannabis Use Disorders, 2002-2016

It is pretty common knowledge that youth who smoke cigarettes are more likely to smoke mariuana and vice versa. And in that regard, this study doesn’t provide us anything new. However, in tracking long-term quit trends, it does note that quit ratios (the proportion of former smokers among ever-smokers) have increased among adults who have never used marijuana and among those with 30-day marijuana use but without a cannabis use disorder (CUD). It’s good to see quit ratios increase over time. However, one possible extrapolation from this study, if this trend were to continue, is a widening cessation gap between those who do not use marijuana and those with a CUD. While CUD is rare and the trendline is moving in a positive direction nationally (Santaella-Tenorio et al., 2019) it may be of a bigger public health concern in states like Colorado where the trendline is moving the other way (Cerda et al, 2019).
