The association between marijuana and e-cigarette use and exercise behavior among adults

Area of Science:

• Public Health
• Behavioral Science
• Exercise Science

Background:

• Rising prevalence of marijuana and e-cigarette use among US adults.
• Decreasing perceived risk associated with these substance uses.
• Need for research on substance use and exercise patterns in adults.

Purpose of the Study:

• To investigate the association between marijuana and e-cigarette use and specific exercise behaviors.
• To examine relationships with strength training, walking for exercise, and general physical activity.
• To address limitations in prior studies regarding exercise type and age groups.

Main Methods:

• Analysis of data from 2,591 US adults (National Longitudinal Study of Adolescent to Adult Health, Wave V).
• Use of one-way ANOVAs and post hoc tests to assess the predictive relationship.
• Follow-up ANCOVAs to examine effects after controlling for covariates.

Main Results:

• Marijuana and e-cigarette use predicted walking frequency, with marijuana users walking most often.
• Non-users walked more than e-cigarette users and dual users.
• No significant differences in strength training or general physical activity were observed between groups.

Conclusions:

• Findings challenge the stereotype of substance users being less physically active.
• Marijuana and e-cigarette use may not be linked to sedentary behavior.
• Further research is needed to explore the underlying mechanisms for these associations.
