SDG 3 — Good Health and Well-Being
The UN goal to ensure healthy lives and promote well-being for all at all ages, including a target on substance use.
SDG 3 Good Health & Well-beingWhat is it?
SDG 3 is the third UN Sustainable Development Goal: ensure healthy lives and promote well-being for all at all ages by 2030, with targets spanning maternal health, disease, and — under Target 3.5 — strengthening prevention and treatment of substance use.
Why does it matter?
It provides a shared global framework and accountability structure that directs monitoring, funding, and policy toward health outcomes, including addiction treatment and mental health.
How does it work?
Targets and indicators let countries measure and report progress comparably; Target 3.5 specifically calls for strengthening prevention and treatment of substance use, including narcotic drug abuse.
Who benefits?
Populations with unmet health needs benefit as governments and institutions coordinate action toward common, measurable goals, including expanded access to treatment.
Who may be disadvantaged?
National averages can mask inequities — rural, low-income, and marginalized populations may lag even as aggregate indicators improve, if data is not disaggregated.
What evidence exists?
WHO tracks SDG 3 indicators, including Target 3.5 on substance-use treatment coverage, and reports show persistent gaps between treatment need and treatment availability worldwide.
What tradeoffs exist?
A single global goal aligns effort but can oversimplify; broad targets may not capture the local access barriers that determine whether care actually reaches people.
Common misconceptions
SDG 3 is not only about infectious disease or maternal health — mental health and substance use are explicit parts of the goal, not afterthoughts.
