- Lifetime prevalence of alcohol use disorder in ADHD adults is 28%, versus 14% without ADHD
- Among adolescents with ADHD, 35% report nicotine dependence by age 17
- Childhood ADHD untreated increases adult SUD by 2.5 times (HR 2.5)
- ADHD with anxiety doubles SUD risk (OR 2.1)
- Genetic overlap: 30% heritability shared between ADHD and SUD
- Lifetime marijuana use disorder in ADHD: 24%
- ADHD smokers: 41% daily cigarette consumption rate
