Understanding Stressful Experience as a risk factor for problematic cannabis use: A longitudinal endocannabionoid biomarker study 

​

​Help us understand how cannabis relates to your health! We are currently looking for undergraduate students to participate in our study in determining the biomarkers underlying the relationship between stress, early life trauma and problematic cannabis use among university students. 

You do not need to be a cannabis user to participate in our study. Participants will come in for an hour-long session to complete our survey, get blood drawn, get a take-home saliva sample kit, and complete a survey one year later. For participating, you will be compensated with a 25$ e-gift card for phase 1 and a 35$ e-gift card for phase 2.

Behind the Scroll: A Mixed-Methods Study on Social Media Use Experiences and Mental Health

​Social media use is a large part of our daily life, but its effect on mental health can look very different depending on age, gender, and how people engage with various platforms. Through a short survey you will help up learn more about patterns of social media use across age and gender. You will also have the option to join a small focus group, where you can share your experiences in more detail and receive compensation for your time. Your input will help us better understand when social media use becomes problematic and how to support healthier online experiences.
