OBJECTIVES: Our study investigated (1) the acute effects of vaporised cannabis on...

These effects may have utility in identifying impairment associated with recent use. However, these effects have not been widely investigated among individuals with a pattern of daily use, who may have acquired tolerance. The purpose of this study was to examine the impact...
