Patterns of Substance Use
Substance use spans a spectrum from occasional, low-risk use to harmful use (causing health, social, or occupational harm without dependence) to substance use disorder (characterised by compulsive use, tolerance, withdrawal, and loss of control). Commonly used substances include alcohol, tobacco/nicotine, cannabis, opioids (prescription and illicit), stimulants (cocaine, amphetamines, MDMA), sedatives (benzodiazepines), and psychedelics. Substance use is associated with a broad range of physical and mental health consequences depending on substance, route of administration, frequency, and individual vulnerability. Polysubstance use (use of multiple substances) is common and increases risk complexity. Social, economic, trauma, and genetic factors all influence use patterns. Harm reduction — reducing risks without requiring abstinence — is an evidence-based public health approach.

The evidence
Evidence context
An honest read on how Substance Use has been studied — an evidence tier and the research behind it, not a guarantee and not a ranking of “better.”
Overall pictureResearch-supported
Among the more studied approaches
NICE and WHO guidelines recommend screening (AUDIT for alcohol, DAST for other drugs), brief intervention, and referral to treatment (SBIRT model).
Safety first
Staying safe
General, informational guidance — not diagnostic. A qualified practitioner can advise on your own situation.
- Abrupt cessation of alcohol, benzodiazepines, or opioids in physical dependence without medical supervision is dangerous
- Disulfiram (Antabuse) requires careful patient selection and alcohol abstinence — potentially fatal reactions with alcohol use
