Attention deficit hyperactivity disorder (ADHD) is a neurobehavioral condition estimated to affect over 5 million (approximately 9%) of U.S. children ages 3-17, according to the U.S. Department of Health and Human Services. The principal characteristics of ADHD are inattention, hyperactivity, and impulsivity. The condition typically manifests during childhood, and many patients continue to be affected as adults. Over 50% of children with ADHD are medically treated, with stimulants such as amphetamine and methylphenidate commonly used as first-line treatment. U.S. sales of ADHD treatments were approximately $9 billion in 2014. The 2010 National Survey on Drug Use and Health estimates that 1.1 million Americans over the age of 12 abuse stimulants for euphoric highs and increased performance or wakefulness.
