Brief 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 ie while following participants in an actual patrol car as part of a roadside behavioral assessment ie 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
Detailed Description:
The easing of restrictions on the use of cannabis for recreational purposes presents a new challenge for policing of impaired driving which is to say Driving Under the Influence of Drugs DUI-D specifically cannabis In particular it is not entirely clear how well the tools used by law enforcement officers to detect driving impairment eg behavioral instruments such as the SFSTs as included in the ARIDE battery work for identifying cannabis-induced driving impairment specifically While these instruments are designed to help officers identify driving impairment in general irrespective of cause prior empirical validation work has almost exclusively involved alcohol-induced impairment This study will be conducted within a realistic closed-course driving environment and it seeks to validate the same instruments currently used by law enforcement to detect cannabis-induced driving impairment against a second independent behavioral standard for driving impairment a comprehensive driver evaluation adapted from the same set of driver tests that Californians must pass upon application for an original license or in certain instances when referred to the Department of Motor Vehicles DMV for evaluation of their ability to safely operate a non-commercial class of motor vehicle here referred to as the Modified Driver Performance Evaluation or MDPE
This study seeks to answer the following research questions
I How accurately do behavioral assessments used by officers distinguish between drivers impaired by cannabis and drivers not impaired by cannabis
II How does cannabis affect real-world as opposed to simulated driving performance
