What is it about?
The present study adds to the growing literature examining daily-level associations between affect and substance use among a diverse sample of 1,006 adolescents and young adults. Results provide evidence that associations between positive and negative affect and substance use differ day-to-day based on both substance (alcohol, marijuana, simultaneous alcohol and marijuana use) and whether we consider whether substances were used or the amount of a substance used.

Why is it important?
Results suggest that in-the-moment interventions for alcohol and simultaneous alcohol and marijuana use may be more salient when individuals have higher positive affect than normal, whereas such interventions may be more relevant for marijuana use when negative affect is lower compared to normal levels.
Perspectives
My coauthors and I are thrilled to see this article add to our growing understanding of how affect and substance use vary day-to-day which has significant potential to improve how we target interventions for times when people need them most.
