Cannabis Screening Tools

CPHA has curated screening tools for cannabis dependence and problematic use that may be of use for providers in their practice. Last updated: May 2018.

Severity of Dependence Scale
  • The Severity of Dependence Scale (SDS) is a five-item questionnaire that provides a score indicating the severity of dependence on cannabis. Each of the five items is scored on a four-point scale (0-3). The total score is obtained through the addition of the five-item ratings. The higher the score, the higher the level of dependence. The SDS takes less than one minute to complete.
  • The eCHECKUP TO GO programs are personalized, evidence-based online behavior interventions developed by counselors and psychologists at San Diego State University. They are currently used in more than 600 universities and institutions in four countries. Free trial available.
