Using ecological momentary assessment to quantify Δ‐9‐tetrahydrocannabinol and cannabidiol use across different forms of cannabis: Feasibility in a sample of Canadian young adults reporting frequent cannabis use

Abstract Aims: To establish the feasibility of using ecological momentary assessment (EMA) to estimate total quantities of Δ‐9‐tetrahydrocannabinol (THC) and cannabidiol (CBD) used across different forms of cannabis, and to assess the predictive validity of THC estimates for predicting acute cannabis‐related consequences. Design: 14‐day EMA using a smartphone application to assess cannabis use in real time. Setting: Canada. Participants: Targeted sample of n = 42 young adults (59.52% women, mean age 25 years) reporting frequent cannabis use. Measurements: Surveys completed
