Substance Use
Substance use refers to the consumption of alcohol, cannabis, opioids or other drugs. Substance use may lead to substance use disorders, overdose, infectious diseases or other complications. Reducing the harms associated with substance use can prevent injury, illness or death. We provide expertise and tools to help you plan substance use programs, research and policies.
