Effects of acute cannabis inhalation on reaction time, decision-making, and memory using a tablet-based application

Daily cannabis users show less impairment in reaction time and short-term memory after smoking than occasional users, suggesting they develop tolerance to some acute effects. In a tablet-based test battery, occasional users slowed down and remembered fewer shapes after smoking cannabis with 15–30% THC, while daily users did not differ from non-users on those measures. On a gap-acceptance decision task, daily users took longer after smoking but maintained accuracy, possibly prioritizing correctness over speed. The findings indicate that tolerance to certain psychomotor and cognitive effects can develop with daily use, and that tablet-based assessments may help detect recent cannabis impairment.
