Drug or Substance use/misuse/abuse Prevention is defined broadly as an intervention designed to address the social and environmental determinants of what might lead to drug and alcohol abuse.
It is aimed at changing the personal, social and/or environmental factors that can contribute towards delaying or avoiding the onset of drug use and/or the avoidance of drug use becoming harmful or problematic. It is undertaking an action that makes drug misuse less likely with a focus on the promotion of health and well-being. For young people it involves preventing and delaying premature and under age illegal use of "legal" and socially accepted and available substances such as alcohol and tobacco.
