Summary
In a true experiment, roughly 300 volunteer participants will smoke active cannabis, a
corresponding placebo, or no substance at all (control). Next, participants will complete a
drive test and then be observed by actual California Highway Patrol (CHP) officers who will
attempt to classify participants as impaired or unimpaired. CHP Officers will evaluate
participants in the context of driving (i.e., while following participants in an actual
patrol car), as part of a roadside behavioral assessment (i.e., the Advanced Roadside
Impaired Driving Enforcement, or ARIDE, battery, which includes Standardized Field Sobriety
Tests, or SFSTs), and as part of a Drug Recognition Expert (DRE) evaluation conducted
indoors.
