Diversion is particularly a problem among adolescents, who are easily influenced by peer pressure. In some cases, adolescents steal drugs from their parents and give or sell them to their friends. Older individuals may also receive diverted drugs or engage in stealing, prescription tampering, and illegal purchases of drugs over the Internet. Many abusers use two or more substances; for example, diverted Ritalin is often used in combination with alcohol and/or other drugs.
According to Zacny and colleagues in their article on opioid abusers of prescription drugs, there are four major types of abusers: (1) those who abuse or depend on only prescription drugs and not other drugs, (2) those who normally abuse illegal opioids such as heroin and will use prescribed opioids when they cannot obtain heroin, (3) those who primarily use other drugs but who sometimes use prescription opioids to gain an enhanced or different type of euphoria, and (4) those who have legitimate medical problems and sometimes develop a dependence on opioids. (Note that most experts agree that patients who experience severe pain and have no past history of abuse or dependence usually do not develop an addiction to a prescribed scheduled drug.)
In a study reported in 2005 in Addiction, the researchers sampled nearly 11,000 college students in 2001 on their abuse of prescribed stimulants, including Adderall, Dexedrine, and Ritalin. The researchers found that higher rates of abuse were found in students in northeastern colleges with competitive admission standards. They also discovered that abuse was more common among students who were white males. Members of fraternities and sororities were more likely to abuse stimulants than other students. In addition, abusers were more likely to report that they also abused alcohol, cocaine, marijuana and Ecstasy.
Experts report that there are several major ways to decrease prescription drug diversion, including the implementation of state prescription drug monitoring programs; further education of health care professionals, such as doctors and nurses; and plans to prevent theft and fraud, such as preventing theft from pharmacies and also prosecution of illegal Internet pharmacies.
OxyContin, a timed-release form of oxycodone, was partly developed to reduce its abuse potential because the medication is gradually delivered over time. Unfortunately, abusers subsequently discovered that the drug could be crushed and swallowed or injected, so that the entire drug would be absorbed at once.
