More cannabis – more alcohol and tobacco!Cannabis Use and Alcohol Consumption: Alcohol remains one of the leading contributors to preventable deaths in the United States, ranking behind tobacco and physical inactivity. The study highlighted that cannabis use was positively associated with alcohol consumption, with participants consuming an average of 0.45 additional alcohol-containing drinks on cannabis use days compared to non-use days. Previous research corroborates this finding, with studies showing that co-use of cannabis and alcohol often leads to an increased duration of intoxication and heightened consumption. This co-use behaviour is complex—sometimes substitutionary (replacing alcohol with cannabis) but often complementary (enhancing the intoxicating effects of both substances).
Cannabis Use and Cigarette Smoking: Cigarette smoking claims approximately 480,000 lives annually in the U.S., primarily due to its role in diseases such as lung cancer, chronic obstructive pulmonary disease, and cardiovascular illnesses. The study found that cannabis use was associated with an increase in cigarette smoking, with participants smoking an additional 0.63 cigarettes on cannabis use days. Historically, individuals who smoke cigarettes are more likely to use cannabis, and cannabis use has been linked to reduced smoking cessation success and increased risks of relapse. The findings align with earlier studies that identified a temporal association between cannabis use and subsequent cigarette consumption.
