Prescription drugs, while often providing enormous benefit to those for whom they are prescribed, are also frequently abused by those patients, or bought and sold on the street for recreational usage. Pill abuse is on the rise. Prescriptions that are often used illegally include both uppers and downers. Opiate painkillers including Oxycodone, Fentanyl, and Suboxone are vastly popular and extremely addictive. Benzodiazepines like Xanax are frequently used to self-treat anxiety. Amphetamines, such as Ritalin or Adderall, are popular on campuses as students seek to gain a study advantage. Use of prescription drugs, especially if outside the purview of a physician, can lead to addiction. Further, it often escalates to other, cheaper, more dangerous drugs, as the need for a fix increases over time. Even when prescription drugs are prescribed legally, they can be easily abused. Drug testing which includes examination of the levels of the drug in the body can detect usage amounts and determine if the consumption was in accordance with the prescribed amount or not.
