+This page houses datafiles related to the COMN Project (Colorado-Minnesota Collaboration). Currently, there are three related projects.
+COMN1 and 2: The Effects of Cannabis Legalization and Persistent Use: A Longitudinal Study of Two Twin Cohorts (COMN) is a project examining the long-term impact of Recreational Cannabis Legalization. It includes approximately 4,500 participants from twin cohorts in Colorado and Minnesota (including the LTS and CTS subsamples from IBG). We will use these data to address whether years of RCL access affect cannabis use, alcohol use, mental health, and physical health. We also hope to determine whether health problems are associated with increased post-RCL cannabis use and identify individual differences in cannabis use and consequences. The 2nd grant was funded in 2024 (COMN2) and data collection began in 2025.
+COMN Paths: The Colorado-Minnesota Parents, Adolescents, Temperament, and Health Study (COMN Paths) seeks to better understand adolescent development, including individual (temperament) and contextual (parents, families, peers, schools, neighborhoods, communities) risk and protective factors for cognitive, behavioral, social, and emotional functioning. The purpose of the study is to address questions regarding intergenerational transmission of behaviors and the effects of marijuana legalization. The PATHS Study is the first study, to our knowledge,  examining effects of marijuana legalization on parents and families.  The COMN PATHS Study is a phase of our COMN (Colorado-Minnesota) Study, which began in 2017 and assessed the impact of cannabis legalization. Data collection began in 2022 and is ongoing.
+Potency: The Potency (or Concentrates) study focuses on a group of individuals selected for high-potency cannabis users (from the LTS, CTS, and CoTwins samples). The study represents is a unique opportunity to rigorously test critical hypotheses about how high-potency concentrates affect psychopathology and psychosocial functioning. This study does NOT include any data from Minnesota.
