Les effets du cannabis sur la santé

Abstract: Cannabis remains the most widely used illicit substance throughout the world with approximately 166 million consumers annually. In comparison with the general population, cannabis users have a reduced socioeconomic level, a higher prevalence of unemployment and a lesser overall satisfaction with life. Cannabis use represents a risk factor for physical and mental illness. In vulnerable patients, cannabis worsens certain mental disorders, especially anxiety disorder and suicidal conduct. The relationship between cannabis and schizophrenia is very close. Patients with certain schizophrenia vulnerability who use cannabis increase their risk of developing the disease. Genetic, biological and environmental factors are likely to be implicated in this process. [Copyright &y& Elsevier]
