A new study published in the journal of Drug and Alcohol Dependence has linked ADHD and conduct disorder to increased tobacco and alcohol use among adolescents. The latest research, out of the Cincinnati Children's Hospital Medical Center, studied over 2,500 teens between the ages of 12 and 15, finding that "teens with a diagnosis of ADHD and conduct disorder had a three- to five-times increased likelihood of using tobacco and alcohol and initiated use at a younger age than those who had neither disorder. " Teens who showed only a diagnosis of ADHD were associated with increased tobacco use but not alcohol use. The study is the first of its kind to assess this association among the young age group, and researchers explain that early intervention will be key to preventing dependence upon these substances later in life.
