THC's (Delta-9-tetrahydrocannabinol) impact on the teen brain is significant, as this period is critical for brain development. During adolescence, connections within the brain are formed and reinforced. THC binds to CB1 receptors in the endocannabinoid system, which influences brain functions such as anxiety, pain, memory, and behavior. However, THC can disrupt normal signaling and structural changes in the developing brain Animal studies have shown that THC exposure during adolescence can lead to long-lasting memory and learning issues. Human studies also indicate that cannabis use is linked to accelerated degeneration of the brain.

High-potency cannabis products pose additional risks. While smoking marijuana remains the most common method of use among teens, vaping cannabis concentrates is on the rise. Studies indicate that high-potency cannabis (defined as 10% THC or higher) is associated with a higher risk of psychosis. The health impacts of these concentrated cannabis products are largely unstudied, presenting new and alarming risks.

Public health officials recommend that parents talk to their children about the risks of cannabis use. Additionally, parents should avoid using cannabis in front of their children, as positive attitudes towards teen cannabis use can hamper efforts to educate teens about the risks.
