For teens and adults with attention deficit hyperactivity disorder (ADHD), using medication to treat the condition may significantly reduce the risk for drug and alcohol abuse, according to new research.
The risk of substance use problems during periods of medication use was 35 percent lower in men and 31 percent lower in women in the study. The results are based upon nearly 3 million people with ADHD in the United States.
“This study contributes to growing evidence that ADHD medication is linked to lower risk for many types of harmful behavior, including substance abuse. The results also highlight the importance of careful diagnosis and compliance with treatment,”
says Patrick D. Quinn, a postdoctoral researcher in the Indiana University Bloomington College of Arts and Sciences’ psychological and brain sciences department, who led the study.
Many Factors Involved
As one of the largest analyses on the risks and benefits of ADHD medication, the study drew on anonymous healthcare data from 146 million people with employer-based health insurance in the United States from 2005 to 2014.
Specifically, the researchers mined the data to identify people with ADHD whose records showed periods of ADHD medication use and periods without ADHD medication use—as well as one or more visits to the emergency room due to drug or alcohol use. They then calculated the odds of the visits occurring during the person’s use of ADHD medication versus the same person’s non-use of ADHD medication.
“Many factors can influence who receives ADHD treatment, including socioeconomic factors, health care access, the strength of support networks, and disorder severity,” Quinn says. “Although no single study of real-world treatment practices can definitively show whether medication use lowers risk, studying the same people at different points in their medical history helps us control for these factors and isolate the role of medication in their behavior.”
Of the nearly 3 million people with ADHD in the study’s database, about 57 percent experienced periods in which they were and were not prescribed medication to treat the disorder. About 2 percent experienced an emergency room visit due to substance abuse. The median age of the study’s participants was 21 for men and 28 for women.
The majority of the ADHD medicines used in the study were stimulants such as Adderall, an amphetamine, and Ritalin, or methylphenidate. A significantly smaller number used nonstimulant ADHD medication such as Strattera, or atomoxetine.
“While concerns about prescribing medications to treat ADHD that have the potential for abuse are understandable, this study provides further evidence that the use of these medications is not associated with increased risk of substance use problems in adolescence or adulthood,” Quinn says.
“Rather, this and other recent studies find that the risk of such problems is lower during and after periods of use of these medications.”
The National Institutes of Health’s National Institute of Mental Health and National Institute on Drug Abuse supported the research.
