Alcohol use and cannabis craving in daily life: Sex differences and associations among young adults.

Background: Alcohol and cannabis are commonly used together by young adults. With frequent pairings, use of one substance may become a conditioned cue for use of a second, commonly co-used substance. Although this has been examined for alcohol and cannabis in laboratory conditions and with remote monitoring, no research has examined whether pharmacologically induced cross-substance craving occurs in naturalistic conditions.

Enhancing causal inference in population-based neuroimaging data in children and adolescents.

Recent years have seen the increasing availability of large, population-based, longitudinal neuroimaging datasets, providing unprecedented capacity to examine brain-behavior relationships in the neurodevelopmental context. However, the ability of these datasets to deliver causal insights into brain-behavior relationships relies on the application of purpose-built analysis methods to counter the biases that otherwise preclude causal inference from observational data. Here we introduce these approaches (i.

Prospective associations between sleep, sensation-seeking, and mature screen usage in early adolescents: findings from the Adolescent Brain Cognitive Development study.

Study Objectives: Early exposure to mature content is linked to high-risk behaviors. This study aims to prospectively investigate how sleep and sensation-seeking behaviors influence the consumption of mature video games and R-rated movies in early adolescents. A secondary analysis examines the bidirectional relationships between sleep patterns and mature screen usage.
