Cognitive sphere of cannabis drug users

The article presents a comparative analysis of the cognitive sphere (in particular, the level of intelligence) of cannabis drug users depending on the length of drug usage: up to 5 years, from 5 to 10 years, more than 10 years. We have undertaken a study of the cognitive functions of people who do not use drugs. Drug users and the control group have secondary vocational education. For diagnosing intellectual abilities we have used a shortpreliminary test. The results obtained have shown the changes in the general level of intelligence depending on the length of drug usage. The findings can be used in the field of practical narcology and psychiatry.
