Delta-8-THC vs. Delta-9-THC on Simulated Driving Performance
Recruiting
Delta-8-THC is an isomer of delta-9-THC that has become widely available due to the legalization of hemp and its derivatives. Very little controlled research has been conducted with delta-8-THC and some research suggests it produces similar effects to delta-9-THC, albeit at lower potency. The present study will evaluate the dose effects of delta-8-THC, compared with delta-9-THC, on simulated driving performance, field sobriety tests, cognitive performance, and biomarkers of exposure to cannabino...
