What is substance use disorder?

Substance use disorder (SUD) - also known as addiction - happens when your body and mind become dependent on a substance to function. This can happen with substances such as alcohol, opioids, stimulants, cannabis and tobacco. Many people do not believe they will be become addicted to the substances they use. But substance misuse can quickly lead to addiction. Symptoms may include:

  • Blackouts or memory loss
  • Mood swings or frequent arguments with loved ones
  • Continual use of the substance to deal with problems, relax or feel better
  • Nausea, vomiting and headaches
  • Lack of energy and motivation
  • Spending money excessively
  • Behavior changes or poor hygiene/grooming
  • Continuing to use the substance despite negative effects on health, relationships, job or finances
