title: Cannabis Use Disorders Predispose to the Development of Sexually Transmitted Diseases among Youth.
abstract: BACKGROUND
  Previous cross-sectional studies involving adults suggest that sexually transmitted diseases (STD) such as cocaine use disorders and opioid use disorders are associated with the development of sexually transmitted diseases (STD). However, it is less clear whether cannabis use disorders (CUD) are associated with the development of STDs, or whether those associations extend to adolescent populations. Longitudinal studies examining those associations are particularly scarce. The current report provides findings from a longitudinal study that examined the relationship between STD and CUD among youth transitioning to young adulthood.
  
  
  METHODS
  The subjects in this longitudinal study were initially recruited when the index sons of these fathers were 10-12 years of age, and subsequent assessments were conducted at age 12-14, 16, 19, and 22. Multivariate logistic regression and path analyses were conducted.
  
  
  RESULTS
  At age 22, of the 345 subjects, 30 subjects were diagnosed with one or more STD, and 105 were diagnosed with a CUD. STDs were almost four times as common among those with a CUD as among those without a CUD, which was a significant difference. Path analyses demonstrated that peer deviance mediated the association between a measure of risk for SUD knows as the TLI and CUD, and that peer deviance mediated the association between TLI and STD. Risky sexual behaviors were common.
  
  
  CONCLUSIONS
  These finding suggest that cannabis use disorders (CUD) predispose to the development of sexually transmitted disorders (STD) among youth. These findings also suggest that peer deviance mediates the development of STD and of CUD among teenagers making the transition to young adulthood.
