New methods to detect cannabis impairment in drivers

Novel approaches to assessing cannabis impaired driving

['FUNDING_R01'] · UNIVERSITY OF COLORADO DENVER · NIH-10829900

This study is looking for new ways to tell if someone is too high on cannabis to drive safely, using a driving simulator and special devices to check how well they can move and see before and after using cannabis, and it’s open to both occasional and daily users to help keep our roads safer.

What this research studies

This research investigates innovative ways to assess whether drivers are impaired by cannabis. Using a driving simulator, the study will test portable devices that measure psychomotor and eye movement performance before and after cannabis use. Participants will include both occasional and daily cannabis users, and the research will analyze how different factors like dosage and timing affect impairment. The goal is to develop accurate methods for public safety personnel to identify cannabis-impaired driving effectively.

Who could benefit from this research

Good fit: Ideal candidates for this research are individuals who use cannabis, including both occasional and daily users.

Not a fit: Patients who do not use cannabis or those who are not involved in driving may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved safety on the roads by providing reliable methods to detect cannabis impairment in drivers.

How similar studies have performed: Other research has shown promise in developing methods for detecting impairment from various substances, but this specific approach to cannabis impairment is relatively novel.
