Older substance misusers still deserve better treatment interventions–an update (Part 3)

Abstract

Substance use and misuse are best viewed through the framework of a multifactorial biopsychosocial model, which acknowledges the interplay of genetic, familial, physiological, psychological and social factors. Age, role, gender, social group and peer pressure, the family, community and occupational environment, as well as overall cultural values and controls on substance use, will act upon substance-taking behaviour.
