Procedure
Individuals accessed the online survey through the Qualtrics platform. After reviewing the informed consent form, eligible emerging adults who consented to participate were directed to the survey. The survey consisted of five randomized vignettes, with one from each of the independent variables explored (frequency of consumption, polysubstance use, method of consumption, family history, and potency). Each vignette was followed by a set of risk perception questions. Participants were then asked a series of socio-demographic questions, including history of personal cannabis consumption.
