Many adults ages 65 and older who regularly use cannabis have driven under its influence. Yet there is little research to understand how cannabis affects driving in this age group. Conditions that may affect older adults, such as aging brain or slowing metabolism – might worsen cannabis’ effects on driving. The effects of cannabis in older adults might also vary depending on whether they use it daily or less often. We aim to learn how inhaled cannabis affects driving performance in older adults. We will investigate how age, underlying brain function, and frequency of use influence cannabis’ effects on driving. Our ultimate goal is to support driving safety among older adults.
