Analysis reveals pupillary dynamics correlate with acute cannabis use, highlighting implications for drug impairment assessments.
Introduction Acute cannabis use has been found to affect pupil size and pupillary dynamics. Law enforcement may consider ocular changes in their examinations to determine drug impairment and the source, including from cannabis. A limited number of studies have used pupillometer technology to provide an objective measure of pupillary changes associated with cannabis use. The purpose of the study was to examine the sensitivity and specificity of pupil size and dynamics, measured with a pupillometer, associated with recent cannabis inhalation.
