Understanding drug dependency

Drug dependency can involve illegal drugs, prescription medicines or over-the-counter medicines. Each substance carries different risks, but the impact on families can feel similar.

Published 13 October 2026

Different substances, different risks

Drugs affect the body and brain in different ways. Some carry a high risk of overdose, others of mental health effects, and others of physical dependence. FRANK provides reliable, substance-specific information.

Prescription and over-the-counter medicines

Dependency isn't limited to illegal drugs. Some prescribed or over-the-counter medicines, such as certain painkillers, can also lead to dependence. A GP or pharmacist can advise.

Mixing substances

Using more than one substance at a time, including alcohol, can significantly increase risk.

Treatment and support

Local drug and alcohol services, often accessible through a GP or by self-referral, can offer assessment, treatment and harm-reduction support.

Key considerations

  • Never assume a substance is safe because it is prescribed or legal.
  • Overdose risk can increase after a period of not using.
  • If you suspect an overdose, call 999 immediately.

Suggested next steps

  • Look up specific substances on FRANK.
  • Find local services via the NHS.
