Examine the Feasibility of a Standardized Field Test for Marijuana and Alcohol Impairment: Laboratory Evaluations

Summary

Alcohol and Cannabis (CNB) are two of the most widely used intoxicants. The effects of driving while intoxicated on alcohol are well documented, resulting in numerous drunken driving laws and regulations. As CNB begins to be decriminalized, medical CNB use allowed in multiple U.S. states, and perception of harmfulness falls, CNB use is predicted to rise and it will become increasingly common to publicly encounter persons who recently used the drug. An area of potentially high concern is if ever-greater numbers of CNB users and its legalization will increase the risk of driving while intoxicated from recent CNB use, thereby increasing the risks to public safety. This study aims to examine the combined effects of smoking marijuana and drinking alcohol on simulated driving.
