Patterns of inattentive and hyperactive symptomatology in cocaine-addicted and non-cocaine-addicted smokers diagnosed with adult attention deficit hyperactivity disorder.
Despite a robust relationship between Attention Deficit Hyperactivity Disorder (ADHD) and cigarette smoking, as well as increased prevalence of other substance use disorders in these individuals, little is known about the particular patterns of ADHD symptomatology associated with different forms of drug abuse. The present study com- pared ADHD adults with and without cocaine dependence (COCDEP) on severity of ADHD symptomatology. Groups did not differ in smoking rate or degree of nicotine dependence. COCDEP ADHD smokers reported significantly more childhood and adult hyperactive/impulsive symptoms, and a higher number of symptoms overall, during adulthood, even after controlling for group differences in age and sex. Our finding of a more severe adult ADHD symptom profile among ADHD smokers with cocaine dependence, accounted for by elevated hyperactive/impulsive but not inattentive features, suggests that cocaine use in smokers with ADHD may be driven by excesses in hyperactivity. These findings have important implications for research, since similarities and differences in patterns and severity of ADHD symptomatology may shed light on drug-specific mechanisms. Our results may also point to improved approaches for treatment of substance abuse based on attention to patterns of ADHD symptomatology specific to different drugs.
