[Cannabis use among children and adolescents: impacts and consequences]

Abstract

A health policy for the prevention and treatment of cannabis-related disorders is urgently needed in France, given the high prevalence of cannabis use among children and adolescents. Such a policy will require a better understanding of the endo-cannabinoid system and the impact of exogenous cannabinoids in this fragile population. The brain continues to undergo significant development until the age of about 25 years, and cannabis consumption by young people therefore carries specific risks of dependence (frequency and intensity), and of neuroanatomical, cognitive and emotional damage. This article summarizes the available data and offers a medical view of the risks and consequences of cannabis use by children and adolescents.
