ADHD and Substance Abuse
ADHD may last into adulthood about a third to half the time, and some studies have shown that children with ADHD may be more likely than the general population to develop alcohol and substance abuse problems when they get older.
Are Drug Abuse and Alcoholism More Common Among People With ADHD?
Several studies have shown a strong connection between ADHD, drug abuse, and alcoholism. ADHD is five to 10 times more common among adult alcoholics than it is in people without the condition. Among adults being treated for alcohol and substance abuse, the rate of ADHD is about 25%.
It is also more common for children with ADHD to start abusing alcohol during their teenage years. In one study, 14% of children ages 15-17 with ADHD had problems with alcohol abuse or dependence as adults, compared to peers without ADHD. Another study found that at a mean age of 14.9 years, 40% of children with ADHD began using alcohol, compared to 22% of children without an ADHD diagnosis -- a strong predictor of alcohol and substance abuse in adulthood. Young adults (mean age of 25), on the other hand, were just as likely to use alcohol whether or not they had an ADHD diagnosis, but those with ADHD were likelier to use alcohol excessively .
