Psychomotor Function in Chronic Daily Cannabis Smokers during Sustained Abstinence

Conclusions/Significance: Sustained cannabis abstinence moderately improved critical tracking and divided attention performance in chronic, daily cannabis smokers, but impairment was still observable compared to controls after 3 weeks of 

abstinence. Between group differences, however, need to be interpreted with caution as chronic smokers and controls were not matched for education, social economic status, life style and race.
