Although cigarette smoking has long been weakening, cannabis use is on the rise and, inexplicably, cannabis users also smoke cigarettes. A new study informs that marijuana use was related with an increased commencement of cigarette smoking among non-cigarette smokers. They also found adults who smoke cigarettes and use marijuana are less likely to resign smoking cigarettes than those who do not use marijuana. Former smokers who use marijuana are also more likely to revert to cigarette smoking.

Until now, little was known about the relationship between marijuana use and smoking cessation or reversion over time in the general adult population.

Developing a better understanding of the association between cannabis use and cigarette use changes is critical and timely as cigarette smoking rests the leading preventable cause of premature death and disease, and use of marijuana is on the rise in the U.S.

The study suggests that cannabis use — even in the absence of cannabis use disorder characterized by problematic use of cannabis due to impairment in functioning or difficulty quitting or cutting down on use- is related with increased odds of smoking onset, relapse, and persistence. As marijuana use is much more common than marijuana use disorder, its potential impact on cigarette use in the general community may be larger than approximations based on studies of marijuana use disorder alone, according to the scientists.

A previous study showed that the use of marijuana by cigarette smokers had increased intensely over the past two decades to the point where smokers are more than 5 times as likely as nonsmokers to use cannabis daily.

Additional attention to marijuana use in tobacco control efforts and in clinical settings aimed at reducing cigarette smoking and smoking related negative costs may be warranted. Understanding the possible links between marijuana use and cigarette initiation in youth is needed given that fresh data propose marijuana use is more common among adolescents than cigarette use.
