Marijuana consumers do not typically use cannabis and alcohol in combination with one another, regardless of whether they are consuming cannabis for medicinal or social purposes, according to data published online ahead of print in the journal Addiction.
Investigators with the RAND Drug Policy Research Center and the University of California, Irvine surveyed marijuana use patterns among participants between the ages of 18 and 91 in four states: Colorado, New Mexico, Oregon, and Washington. (The use of marijuana for medicinal purposes is legal in New Mexico, while laws in Colorado, Oregon, and Washington permit adults to possess and purchase cannabis for both medicinal and/or recreational purposes.)
Authors reported, "Individuals who use cannabis do not commonly use it with alcohol, irrespective of whether they are consuming cannabis recreationally or medically." They concluded, "Fewer than one in five recreational users report simultaneous use of alcohol and cannabis most or all of the time and less than three of medicinal users report frequent simultaneous use of alcohol and cannabis."
An abstract of the study, "A baseline view of cannabis use among legalizing states and their neighbors," appears online here.
