Summary
Early cannabis use in adolescents significantly predicts later anxiety symptoms, but anxiety does not predict changes in cannabis use. This highlights the need for integrated anxiety management in adolescent cannabis use interventions.
Area of Science:
- Adolescent Health
- Mental Health Research
- Substance Use Studies
Background:
- Bidirectional associations between adolescent anxiety and cannabis use are debated.
- Understanding the developmental trajectory is crucial for effective interventions.
Purpose of the Study:
- To prospectively examine the co-development and bidirectional influences of anxiety symptoms and cannabis use during adolescence.
- To clarify the directionality of the relationship between early cannabis use and anxiety.
Main Methods:
- Longitudinal study with 250 adolescents (14-17 years) of predominantly Hispanic ethnicity.
- Three bi-annual assessments over a 1-year period.
- Latent growth curve modeling (LGCM) and parallel process growth curves analyzed associations.
Main Results:
- Higher initial cannabis use predicted persisting self-reported anxiety over time (b=0.28, p=0.024).
- Early anxiety levels did not significantly influence the rate of change in cannabis use.
- Analyses controlled for concurrent depression, alcohol, and nicotine use.
Conclusions:
- Early adolescent cannabis use appears to be a stronger predictor of subsequent anxiety than vice versa.
- Prevention and intervention programs for adolescent cannabis use should incorporate anxiety management strategies.
- Replication with diverse samples and longer longitudinal designs is recommended.

Social anxiety disorder, also known as social phobia, is characterized by an intense fear of social situations where one might face humiliation, rejection, embarrassment, or negative evaluation.

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
