Series from the Lancet journals 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.
