Funded by the National Institutes of Health (1R21DA048067) the long-range goal of this work is to improve our understanding of the consequences of medical marijuana use in later life. A study that examines older adults pre-exposure to medical marijuana and systematically tracks medical marijuana initiation, dosage, and psychomotor functioning is needed.
Thus, the current study will test medical marijuana use as the exposure variable in adults age 50 and older and simulated driving performance (i.e. errors in response time, attention, and executive functioning tasks that predict on-road performance) as the primary outcome.
Medical marijuana use is increasing among adults 50 and older. Both the National Institute on Drug Abuse (NIDA) and the National Institute on Aging (NIA) have identified the need to understand how habitual use of medical marijuana affects psychomotor functioning in real world tasks such as driving. The current proposal will address this question by examining medical marijuana use in the context of driving performance among adults 50 and older.
