Concurrent use of alcohol and cannabis leads to higher levels of drinking in the longer term
Co-existing use of alcohol and cannabis can lead to negative outcomes such as the development of a substance-use disorder, poor academic and occupational performance, and psychiatric disorders when compared to use of either drug alone. New research that examines simultaneous alcohol/cannabis use has found higher levels of drinking after 18 months. These results and others will be shared at the 46th annual scientific meeting of the Research Society on Alcohol (RSA) in Bellevue, Washington.

Study First to Show Statewide Cannabis-related Deaths in Florida
There has been a 1,107.01 percent increase in the number of people with medical cannabis cards in Florida (2018 to Jan. 27). One key reason is because many people believe cannabinoids – plant derived, medicinal, and synthetic or chemically engineered – are safe to use. A study shows that 386 people died in Florida as a result of cannabis use; of these, 258 cases were caused by synthetic cannabis. Nearly 88 percent were men; 28 percent of deaths were in those ages 45 to 54, compared to 9 percent in those ages 8 to 24. Nearly 99 percent of individuals using cannabis and synthetic cannabis died from accidents.

About the cannabis and alcohol relationship: it’s complicated
Not only is cannabis the most commonly used illicit – in a number of states – drug among people who drink alcohol, cannabis is also by far the most commonly used illicit drug in the U.S. overall.
