HREC: This study has been reviewed and approved by the Monash University Human Research Ethics Committee [13390]. 


There are about 200 million people who consume cannabis worldwide. Past research studies have shown that heavy and long term cannabis consumption is accompanied by changes to a person’s brain, cognition, and mental health. Researchers have observed that these changes may depend on the levels and interactions between the compounds (cannabinoids, e.g. delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD)) in the cannabis plant.

This study seeks to understand the relationship between different cannabinoid compounds, and the overall well-being and brain health of long-term regular cannabis smokers. This study is a virtual study limited to certain areas of the Northern Rivers Region of New South Wales.  

Researchers are inviting adults aged 18 to 65 years old who regularly smoke cannabis. Participants must comply with the necessary study requirements. Eligible participants will be compensated for their participation in this study.

Why Participate? 

  • Participants may contribute to an Australian-first study into the different cannabinoid profiles of cannabis and their effects.
  • Participants may get the opportunity to receive a cannabinoid profile of the cannabis they are smoking, analysed using state of the art technology.
  • Participants will be compensated up to $170 for participating in this study.
  • Participants may provide integral insights into the nature of the cannabis they are smoking, and their lived experience to help further the field of cannabis research.

Your Rights

  • If you decide to participate in the study and later feel that you no longer wish to be part of it, you may withdraw at any time.
  • Your records relating to this study and any other information received will be kept strictly confidential, except as required by the law.

Who Can Participate?

  • Adults aged 18-65 years old who regularly smoke cannabis. 
  • Participants must have access to 1) a computer or laptop with internet access and 2) video/ web conferencing, either through their phone or computer.
  • Participants must be able to attend to do 3 online assessments as well as comply with the following requirements for over approximately 4-5 months:
    • Participants must be willing to do virtual interviews, questionnaires and brief cognitive tests. 
    • Participants must be willing to provide sample(s) of the cannabis they have been smoking for the study duration. The study team will further discuss this with the participant.
