1 hour webinar recording and handout, available on demand.


This webinar is for teachers, parents and others who are seeking information about adolescent cannabis use and reducing cannabis-related harm. Cannabis is the most commonly used illicit drug among young people worldwide. In Australia, around 1 in 10 high school students (12-17 years-old) have ever used cannabis, a rate that has remained relatively stable for over 10 years.

Unfortunately, cannabis potency (THC content) has since increased remarkably, which has been found to be associated with higher rates of cannabis dependence, psychosis, anxiety and depression. This relationship between cannabis potency and harms is especially concerning considering that young people can be particularly vulnerable to the harmful effects of cannabis. 


This webinar will provide: 

  • An understanding of the prevalence and characteristics of young people using cannabis.
  • Information on cannabis potency (THC content), and the different types of cannabis products. 
  • Information on the evidence of how cannabis impacts adolescent health.
  • An evaluation of the evidence around cannabis prevention, treatment and harm reduction.
