WHO Report: The health and social effects of nonmedical cannabis use
Almost 20 years have passed since the World Health Organization (WHO) published a report on the health consequences of cannabis use. Since then there has been significant research on the effects of cannabis use on health.
This update on the health and social consequences of nonmedical cannabis use, with a special focus on the effects on young people and on long-term frequent use, was prepared by the Management of Substance Abuse (MSB) unit in the Department of Mental Health and Substance Abuse (MSD) of the World Health Organization (WHO), Geneva, Switzerland.
The report focuses on nonmedical use of cannabis, building on contributions from a broad range of experts and researchers from different parts of the world. It aims to present current knowledge on the impact of nonmedical cannabis use on health, from its impact on brain development to its role in respiratory diseases.
The potential medical utility of cannabis - including the pharmacology, toxicology and possible therapeutic applications of the cannabis plant - is outside the scope of this report.
