High in the Cloud: Alcohol-, Cannabis-, and Co-Use Before and During Remote Research Participation

The use of crowdsourcing for addiction research has increased exponentially in recent years, but the extent to which the populations we expect results to generalize to might be engaging in substance use while participating in remote research has not been formally quantified. Understanding rates of day-of-study substance use on crowdsourcing platforms may be especially relevant given immediately recent use can alter cognitive and behavioral decision-making processes (e.g., attention, behavioral economic drug purchase tasks) that are often the focus of online substance use research.
