Cannabis and alcohol are amongst the most popular recreational substances used in North America, especially in young adults. Research has shown that Canadian youth have the highest prevalence of heavy episodic drinking, and are also the most frequent and high risk consumers of cannabis. The use of these substances may disrupt the development of the brain at this important period of neurodevelopment, and may potentially lead to future health risks. Additionally, substances such as cannabis and alcohol are believed to affect synapses, or connections between brain cells, during brain development.
Our group is conducting research on the relationship between high-risk alcohol and cannabis use in youth and synaptic density (i.e. studying the number of connections between brain cells) using brain imaging techniques. We hope to understand how drugs such as cannabis and alcohol may impact brain development and who may be at risk of developing substance use disorders and mental health symptoms.
We are looking for people to participate in this study who:
- Are 16-26 years of age
- Regularly use cannabis OR alcohol
- Do not have any pre-existing serious or unstable health conditions
The study includes the following sessions:
- In-person interview (up to 4 hours). Here we will receive your consent to continue with the study.
- Primary imaging visit. This includes an MRI scan (~1 hour), a PET scan (~4 hours).
If you choose to participate in this study, you will receive financial compensation. In addition, expenses related to the study sessions such as travel and meals will be reimbursed.
