%X Cannabis use may affect drug users¡¯ health and vitality, but few cannabis users seek health care assistance. This study¡¯s objective is to develop an instrument to identify cannabis use disorder among Thai people and investigate its psychometric properties. A two-stage mixed-method research design was implemented. The first phase was conducted by literature review, in-depth interviews, a focus group, cognitive testing, and exploratory factor analysis. The second phase was conducted using a two-stage screening procedure in a field survey conducted among 1,120 subjects. The gold standard for diagnosis was based on one psychiatrist according to Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; DSM-IV-TR) criteria. The optimal cut-off point was £¿9.56 (sensitivity, 92%; specificity, 92%). Confirmatory factor analysis revealed two factors, namely loss of control and impacts of cannabis, with good model fit (comparative fit index [CFI] = 0.926, Tucker¨CLewis index [TLI] = 0.909, root mean square error approximation [RMSEA] = 0.049). The final instrument, consisting of 13 items, was named ¡°Thai Cannabis Risky Use Screening Test¡± or TCRUST
