Table 3 Descriptive means (SD) for driving outcomes under single-task conditions (upper table) and dual task conditions (middle table). Driving outcomes are presented for baseline as well as 120 min, 240 min and 360 min after ingesting cannabis (cannabis) or a control candy (no cannabis) condition. SDLP: standard deviation of lateral position (cm); MS: Mean Speed (km/hr); RT: Reaction time (seconds); SDSP: Standard deviation of speed; Max: maximum speed (km). Descriptive means (SD) of THC, OH-THC, COOH-THC and CBD (bottom table) at baseline and 120 min after cannabis or a control condition. *p < 0.05, different from no cannabis for that time point*; + different from no cannabis at that time point (p < 0.05), but was not significant after the correction for multiple comparisons
