Understanding Prescription Drugs

Learn about prescription drug addiction and substance use disorder

Most individuals who go to the doctor and are prescribed a medication follow the directions of the physician, use the medication as directed, and stop the medication at the appropriate time. Some people, however, discover that the prescription medication they were prescribed causes them to experience pleasant feelings that they do not want to give up. These individuals may find that they crave the effects of the prescription drug and begin to use it in a manner in which it was not prescribed. This is called prescription drug abuse. The most common prescription drugs of abuse include opioid painkillers, anti-anxiety agents, sedatives, as well as stimulants.

Opioid painkillers (narcotics) like OxyContin – which contain oxycodone, and those containing hydrocodone (Norco) are used to manage chronic pain and may be abused in order to obtain the high caused by these drugs.

Anti-anxiety agents and sedatives such as benzodiazepines and hypnotics such as Ambien are used to manage anxiety and promote sleep. These medications can also induce feelings of pleasure in the user, leading to abuse and addiction.

Stimulants such as Ritalin are used to treat ADHD and narcolepsy and provide the user with increased energy and concentration. Abuse of stimulants is especially prevalent among the younger generation to succeed academically.

Prescription drugs are abused for a variety of reasons such as intense well-being, relaxation and stress relief, to lose weight, to increase alertness, peer pressure, prevention of withdrawal, and increased work or scholastic performance. Unfortunately, abusing prescription drugs can cause an incredible amount of interpersonal and health-related problems for the addict. This is only compounded when prescription drugs are combined with other drugs of abuse, such as alcohol and street drugs.

Many individuals operate on the erroneous assumption that because these medications are prescribed by a doctor and approved by the FDA, they are safer than street drugs. This could not be further from the truth, especially as tolerance develops and individuals must take more of the medication to obtain the same high.

Prescription drug abuse is an increasing problem in the United States. While prescription drug abuse affects all age groups, it is most common among younger individuals. Early identification and intervention of prescription drug addiction may prevent more problematic behaviors.


Prescription drug addiction statistics

It’s estimated that 20% of individuals in the United States have used prescription drugs for nonmedical purposes, thereby engaging in prescription drug abuse. Prescription drug addiction is a very serious and growing problem in the US.

Causes and Risk Factors

Causes and risk factors for prescription drug addiction

Researchers thus far have been unable to determine an exact reason for the development of addiction. It’s generally considered to be a multifactorial disorder with multiple factors interplaying to create the addiction. These factors include:

Genetic: Individuals who are born into a family in which a first-degree relative struggles with addiction to prescription drug or other substances are at higher risks for developing an addiction later in their lives.

Biological: Individuals who become addicted to prescription drugs are often prescribed medication for a biological condition – such as pain disorders – and become addicted to the pleasant side effects.

Environmental: Children who grow up in unruly households where addiction runs rampant may be at greater risk for developing an addiction later in life. Additionally, individuals who begin to abuse drugs at an earlier age run the risk of developing full-blown addiction at some point in their lifetime.

Psychological: Many individuals who struggle with untreated mental illnesses attempt to manage the symptomatology through “self-medication” with drugs or alcohol. This can clearly lead to addiction.
