title: Marijuana: an overview.
abstract: Marijuana is a crude, intoxicating drug that has become much more potent in the past decade. Adolescents intoxicated from marijuana suffer from impairment of short-term memory and automobile driving skills. The drug is easily detected in users by means of immunoassay analysis of urine specimens. Frequent use by young adolescents can impede normal maturation and cause or contribute to an amotivational syndrome.
