There is a paradox that the amphetamine class of drugs used in the treatment of Attention Deficit Hyperactivity Disorder (ADHD) is also abused widely in society. There has been considerable effort to educate children concerning the potential problems of abuse and addiction to the drugs. The close parallel between the pharmacokinetic behavior produced by the drugs used in the treatment of ADHD with cocaine, methamphetamine and other abused central nervous system stimulants raises concerns about addiction and cross-substitution of addictive properties between different stimulant drugs. For the purpose of this study the term ‘amphetamine class of drugs’ refers to dexamphetamine, methylphenidate hydrochloride, amphetamine and combined amphetamines used in drug treatments for
ADHD.
