Drugs & medicines

01

Opioids

People dependent on heroin or other opioids may be offered structured treatment that includes medicines such as methadone or buprenorphine, psychosocial support and harm-reduction measures.[NHS]

02

Cocaine and other stimulants

Stimulant problems can involve strong cravings, binge patterns, sleep disruption, anxiety, low mood and cardiovascular risk. Treatment is usually psychosocial rather than based on a standard substitute medicine.

03

Cannabis

Cannabis can become difficult to control and may be associated with dependence, withdrawal symptoms, anxiety or worsening mental health in some people. A careful mental-health assessment is particularly important when paranoia, psychotic symptoms or severe anxiety are present.

04

Benzodiazepines and prescription medicines

Dependence can develop on some prescribed medicines. This does not automatically mean the person has an addiction. Abrupt stopping can sometimes be unsafe, so medication changes should be planned with an appropriate clinician.

Treatment is a healthcare entitlement.

NHS guidance states that people needing help for drug problems are entitled to treatment in the same way as anyone else with a health problem.

Harm reduction matters

Reducing overdose and infection risk, providing naloxone where appropriate, safer injecting support and testing or treatment for blood-borne viruses can save lives while a person works toward broader recovery goals.
