3.1 Parental substance use (drugs)

Substance misuse includes the use of illicit drugs (such as cannabis), pharmaceutical drugs (such as pain-killers, tranquillisers) when used for non-medical purposes (an illicit behaviour), and other substances (such as inhalants) used inappropriately.

Parental substance misuse is a key risk factor for child abuse and neglect. Misuse can compromise parents' ability to consistently provide a stable and safe environment for children, maintain household tasks and routines, and respond to their children’s emotional needs. Financial difficulties can also arise due to substance misuse, compounding the issues faced by the family.

Explanatory notes

Illicit drugs include illegal drugs (such as cannabis, amphetamines, and heroin), pharmaceutical drugs (such as pain-killers, tranquillisers) when used for non-medical purposes (strictly an illicit behaviour), and other substances used inappropriately (such as inhalants). Due to the illegal nature of illicit drugs it is likely that self-reported data underestimate the number of people using these drugs.

Reported usage is based on what drug the person believed they were taking, and it is possible that they may not have known.
