Although marijuana is the most commonly used substance among adults who also drink alcohol, there has been little information connecting the two or comparing the relationship between alcohol and marijuana use.

They also displayed the heaviest drinking patterns. As marijuana has become legalized in multiple states and continues to be considered in many others, this study presents important data for professionals in the science and health fields.
