The current study used a semester-long EMA design to test for differences in self-control (measured by a stop-signal task and perceived self-control demands) in undergraduate students on days they do and do not use cannabis, as well as adjusting for students own typical levels of cannabis use. Differences in self-control were further assessed across methods of consumption (e.g., inhalation vs. ingestion vs. concentrates) on days when students used cannabis. Data from n=196 undergraduates (Mage=20.6; 63.3% female) across 14 weekends in 2021 was examined using Multilevel Modelling to accommodate repeated measures nested within individuals. In this longitudinal design using objective and subjective measures, findings revealed no meaningful differences in self-control among students who did and did not use cannabis, and across the various methods of consumption. Effects were within the smallest effect size of interest limits and results provide reassurance that recreational or occasional cannabis use likely isn't related to self-control.
