Four groups of 10 subjects each, representing different levels of marijuana usage, performed two different psychomotor tasks. One group has never smoked marijuana; one group has smoked marijuana previously but had stopped. The other two groups consisted of habitual smokers of marijuana-one smoked a placebo, and the other smoked marijuana just prior to performing the psychomotor tasts. Consistent patterns of inferior performance were found for the marijuana users on both manipulative and coordination skills.
