P43. Association Between Thalamic Volume and Angry Rumination in Adolescent Cannabis Users

Cannabis (CB) use has been associated with alterations in brain structure and function as well as behavioral challenges including aggression.

In this study, we assessed the relationship between displaced aggression and thalamic volume, which has previously been associated with anger and aggression related behaviors.
