The effect of long-term chronic marijuana use on neuropsychological functioning.
Ten normal subjects who smoked marijuana daily for an average of 5 years and who denied other drug use were examined on a neuropsychological test battery. When compared with normal nonsmoking Ss, minimal differences were observed. It was concluded that long-term cannabis use does not cause a generalized decrement in adaptive abilities which might be related to cerebral impairments.
