Substance use disorder has not been posited as a hypothesis for the high comorbidity between ADHD and substance use disorder because it suggests that substance use disorder causes ADHD, which is not supported by the current scientific understanding of ADHD as a neurodevelopmental disorder with a genetic and biological basis. Instead, the other three hypotheses suggest that ADHD and substance use disorder may have common risk factors, such as genetics, or may influence each other through shared symptoms or cognitive effects.
