Knowledge

Addiction & health

Evidence-informed, non-stigmatizing information about substance use disorders, treatment and recovery.

Three points to remember
  • Substance use does not automatically mean addiction; risk, harm, control and day-to-day functioning matter.
  • Drug use disorders are assessable and treatable health conditions.
  • Care works best when it is ethical, individualized, sustained and connected with broader health and social support.

Understanding substance use

Problems can range from risky or harmful patterns to dependence. A meaningful assessment considers frequency, context, physical and mental health, loss of control, social functioning and continuing use despite harm.

Treatment is not one-size-fits-all

WHO and UNODC recommend evidence-based, ethical and individualized treatment integrated with health and social systems. Care may include assessment, psychosocial interventions, medication where indicated, mental-health care, infectious-disease services, family support and continuing care.

Recovery is a process

Goals may include reducing risk, preventing overdose, improving health, stabilizing daily life, rebuilding relationships, staying engaged in treatment or stopping use. A return to use can be a signal to review triggers, support and treatment intensity rather than a reason for shame.

Youth and families

International prevention standards favor developmentally appropriate, sustained approaches that strengthen family support, school connection, social-emotional skills and healthy environments rather than relying on fear alone.

Emergency: loss of consciousness, abnormal breathing, seizure, chest pain or severe confusion require urgent medical attention.
