Problematic substance use prevention
Many young people experiment with substance use at some point during their development. For some students, this experimentation is considered low risk and may be for a relatively short period of time. For others, it may become excessive and develop into a significant problem.
Substance use continuum
Substance use occurs along a spectrum, which is commonly referred to as a continuum of substance use or substance use spectrum. It ranges from no use to substance use disorder or experimentation to substance use disorder[i],[ii]. A continuum of evidence-based strategies and supports is recommended to address the needs of all those who are coping with substance misuse, regardless of where they fall on the continuum[iii].
