Understanding Codeine

Learn about codeine addiction and substance use disorder

Codeine, one of the most commonly used opioid narcotics in the world, is a relatively short-acting analgesic, with most effects lasting a few hours. A member of the opiate class of narcotic prescription medications, codeine is derived from a member of the opium poppy plant. Opiates include other drugs such as heroin, Vicodin, hydrocodone, OxyContin, and Demerol. Codeine is generally prescribed by a physician to treat mild-to-moderate levels of pain, manage a pesky cough, and occasional treat gastrointestinal problems such as diarrhea. Most individuals who are prescribed codeine to manage a medical illness take the drug directly as prescribed and never have a problem, but some individuals develop an addiction.

Used for centuries to manage pain in chronic pain sufferers, codeine and other opiates are becoming the drug of choice for many drug addicts. In fact, opiates are now the most commonly abused drug in the world. Opiates such as codeine are drugs of abuse due to the powerful effects on the user. In addition to pain relief, in higher doses codeine can lead to a pleasurable euphoric sensation. When opiates enter the central nervous system, they activate the reward system of the brain, allowing for excessive release of pleasurable hormones. It is this feeling that codeine addicts crave.

While many individuals do find that codeine is a miracle drug for the relief of symptoms, codeine addiction is no miracle. Like any addiction, codeine use and abuse can lead to devastating health and interpersonal problems. Many individuals who abuse codeine become tolerant to the mild effects of the narcotic and begin to abuse heavier and stronger narcotics to achieve greater highs. In addition, many individuals with codeine addiction begin to use other drugs such as benzodiazepines and alcohol in order to achieve greater highs. Others may abuse codeine and stimulant drugs in order to reduce the side effects of the stimulants and produce a more mellow high.

Codeine addiction is a serious disorder that can cause much suffering for all involved. Prompt medical treatment and therapy are necessary to reduce the ill-effects of codeine.

Causes and Risk Factors

Causes and risk factors for codeine addiction

While the causes for codeine addiction are not well-understood, addiction is thought to be a combination of a number of factors working together. Some of the causes for codeine addiction include:

Genetic: It’s been determined that addiction to certain substances runs in families. Individuals who have a first-degree relative, such as a parent, who are addicted to substances are more likely to develop an addiction later in life.

Biological: The interaction of codeine in the brain has caused a number of researchers to question whether or not certain individuals are born lacking the neurotransmitters that cause pleasure and well-being. These individuals may be attempting to correct this inborn deficiency by abusing codeine.

Environmental: Individuals who are raised in a home environment in which addiction runs rampant may be at higher risk for developing addiction disorders. In addition, individuals who begin to abuse drugs at an earlier age may be more prone to develop an addiction later in life.

Psychological: Many individuals struggle with undiagnosed mental illnesses that cause a variety of unpleasant symptoms. In order to alleviate these unpleasant emotions, an individual may turn to substance abuse in order to feel more normal.
