Abstract
A laboratory experiment was conducted to compare the effects of two different marijuana dosing techniques on psychomotor tracking performance. Fourteen young, experienced male users were treated with marijuana and then tested on the Critical Tracking Task and the Tracometer. Both tracking tasks were found to be sensitive to the effects of marijuana, though only the Tracometer was sensitive to the difference in dosing technique. The multiple dose technique appeared to produce greater impairment than did the single dose technique. These results suggest that most previous research in this area may have underestimated the effects of marijuana due to the use of the single dose technique.
