Attention deficit hyperactivity disorder (ADHD) may be linked to substance abuse, a new study found.

The study, set to be published in the journal Alcohol and Alcoholism, found that even when accounting for age, race, income, education, childhood adversities and mental illnesses aside from ADHD, people aged 20 to 39 and diagnosed with ADHD were 69% more likely to have a substance use disorder than those without ADHD.

Around half of people with ADHD will have a substance abuse disorder, the study found, compared to only about 23.6% of adults without ADHD.

Researchers collected data from the Canadian Community Health Survey-Mental Health and analyzed findings from 270 people between the ages of 20 to 39 with ADHD and 6,602 people without the disorder.

About 36% of adults with ADHD reported abusing alcohol, followed by cannabis — with about 23% of adults with ADHD abusing the substance. Those with ADHD “were also three times more likely to experience an illicit drug disorder” — not counting marijuana — compared to those without the disorder. Click here to read the rest of the story.
