Lancet Series on drug use

The 1961 UN Single Convention on Narcotic Drugs proposed to end all non-medical use of cannabis, coca, opium poppy, and their derivatives. In the nearly 60 years since then, global drug use and harm have increased despite the better scientific understanding of what interventions are effective, as highlighted by a new Lancet Series on drug use.

The drug use landscape is dynamic and changing. Changes in public attitudes and laws towards drug use have occurred in an increasing number of countries. Global drug production and consumption are increasing as are the risks and harms to health, while new substances continue to emerge. This Series focuses on opioids, cannabinoids, stimulants, and new psychoactive substances. The Series authors review the evidence on the epidemiology of drug use and related harms and interventions (treatment and policies) to address them. They highlight issues that are likely to become increasingly important in the next decade.
