| Sumario: | Although problematic cannabis use is a public health concern, little is known about lower-risk cannabis use beliefs and behaviors. A major stumbling block for research in this domain has been the lack of a methodologically sound, multidimensional measure of lower-risk cannabis beliefs and behaviors. This paper reports the development of the Cannabis Lower-Risk Scale (CaLRS). In Study 1 (N = 510), people who use cannabis were administered a survey containing 69 items that assessed an array of lower-risk beliefs and behaviors. A factor analysis was conducted, and items were subsequently culled. In Study 2 (N = 1008), the factor structure was confirmed revealing a 6-factor scale (21-items) that assesses three lower-risk beliefs (stigma reduction, informed self-regulation, and personal awareness) and three lower-risk behaviors (positive protective strategies, honesty, and limiting behaviors). The implications for research and public health policy and programs are discussed.
