| Key findings | Cannabis produced dose-related impairment on four of five performance tasks, supporting prior evidence of impairment in short-term memory, goal-directed behavior, and choice reaction time. Results on three tasks suggested monetary motivation reduced the drug's performance effects. No performance difference appeared between naive and experienced cannabis users. |
Abstract
The study examined the effect of monetary incentive on the performance of five tasks after two heterogeneous groups of experienced users of cannabis and previously naive subjects had smoked placebo material and two dose levels of cannabis. The performance of the motivated subjects was compared with that of two non-motivated matched groups. Dose-related impairment was found on four of the five tasks, supporting previous findings of cannabis-induced impairment of short-term memory, goal-directed behavior and choice reaction times. Results for three of the tasks suggested that the performance of the motivated subjects was less affected by the drug than was the performance of the non-motivated subjects. There was no difference between the performance of subjects naive and experienced with respect to drug use.
