Who could benefit from this research

Could help

Teens and young adults about 12–20 years old, especially current users of high-potency cannabis concentrates or members of the long-standing twin cohort who can provide health information and biosamples, may be eligible.

Less likely to help

People who do not use cannabis, adults outside the target age range, or anyone unwilling to provide health information or blood samples are unlikely to benefit directly from participation.

What this research studies

If you join, researchers will use an existing long-term twin group that has been followed since adolescence to track mental health and social functioning over time. They'll collect survey information, mental-health questionnaires, and biological samples such as blood to measure THC and other cannabinoids. The team will compare people who use high-potency concentrates, those who use flower or edibles, and those who use little or no cannabis to see how use patterns line up with anxiety, mood, and daily functioning. This work focuses on participants roughly ages 12–20 and uses repeated follow-up visits to see how effects change as people age.

Why it matters

Potential benefit: Results could help doctors, families, and policymakers know which cannabis products carry higher mental health risks for teens and guide safer advice and rules.

How similar studies have gone: Prior research links heavier cannabis use and higher THC exposure to worse mental health, but studies specifically on very high-potency concentrates and long-term psychosocial effects are limited.
