Why are opioids addictive?
Opioids are highly addictive because they flood the brain with endorphins and dopamine, which produce feelings of pleasure, satisfaction, and euphoria. The “high” is so powerful and unlike any natural rush of endorphins and dopamine that the only way a person can experience those feelings again is by using opioids. There are several other genetic, environmental, and lifestyle factors that all contribute to the likelihood of developing an opioid addiction.

What are Opioids?

Opioids are a class of drugs that include synthetic opioids, prescription painkillers, and heroin.1 These drugs are all chemically related and interact with the same opioid receptors in the brain and body. Their effects result in feelings of euphoria, which encourages opioid abuse, dependence, and addiction.

The terms “opiates” and “opioids” are often used interchangeably, but there is a difference between the two. An opiate is a drug that is naturally derived from the opiate poppy plant and an opioid is a broader term that refers to natural or synthetic substances that bind to the body’s opioid receptors.

Opioids are classified as controlled substances by the DEA and their current scheduling is as follows:

Opioid Drug Scheduling
Schedule IHeroin
Schedule IIDemerol (meperidine)

Dilaudid (hydromorphone)

Dolophine (methadone)

Duragesic or Sublimaze (fentanyl)Morphine



Percocet (oxycodone)


Other hydrocodone medications

Schedule IIIBuprenex




Other buprenorphine products

Schedule IVTramadol
Schedule VSome codeine medications (e.g., Robitussin AC)

Side Effects of Opioid Use

When they are used responsibly as prescribed by a doctor, prescription opioid drugs provide effective relief from moderate to severe pain. However, when opioid drugs are abused, they can cause the following short-term side effects:

  • Depressed breathing
  • Drowsiness
  • Constipation
  • Nausea
  • Unconsciousness
  • Coma2

 Long-term opioid abuse may also result in:

  • Tolerance
  • Physical dependence
  • Opioid withdrawal
  • Addiction2

Causes of Opioid Addiction

If a person is addicted to opioids, he or she may feel like they are impossible to live without. An addicted person may also experience irresistible cravings for opioids and succumb to uncontrollable, compulsive opioid use. There is no single cause of opioid addiction, rather, the factors that contribute to opioid addiction often include a person’s genetics, environment, and lifestyle factors.

Researchers believe that many of the genes involved in the body’s reward and pleasure center also play a role in addictive behaviors and opioid addiction. According to the U.S. National Library of Medicine, the genes that are responsible for making opioid receptors may vary, which lead to differences in the opioid receptors’ structure and function. In turn, this also influences how the body responds to opioid drugs.3

There are also several environmental and lifestyle factors that may cause opioid addiction. They include:

  • A history of substance abuse
  • Depression
  • Psychiatric disorders
  • Childhood abuse/neglect
  • Personality traits like impulsivity and sensation-seeking
  • Poverty
  • Associating with people who abuse opioids

Generally, a combination of all the factors listed above determines a person’s likelihood of developing an opioid addiction.

Opioid Addiction Risk Factors

Any opioid use, even short-term, can lead to tolerance, dependence, addiction, and overdose. Therefore, anyone who takes opioid drugs is at risk of becoming addicted to them. Although it is impossible to determine who will become addicted and who will not, here are some of the most common risk factors for opioid addiction:

  • Personal or family history of substance abuse
  • History of criminal activity and/or legal problems
  • History of severe depression and/or anxiety
  • Previous drug or alcohol rehabilitation
  • Association with drug users or high-risk environments
  • Mental disorders/psychiatric problems
  • Young age
  • Thrill-seeking behaviors
  • Heavy tobacco use
  • Poverty/unemployment
  • Stressful life circumstances4

Opioid Addiction: Treatment and Prevention

Opioid addiction can’t always be prevented, but there are several measures that individuals can take to protect themselves from the risks of prescription drug abuse and opioid addiction. A few strategies include:

  • Closely following the directions or instructions provided by the pharmacist when taking prescription opioid drugs.
  • Being aware of potentially dangerous drug and alcohol combinations and interactions.
  • Talking to a doctor before changing prescription doses.
  • Not taking anyone else’s prescription opioids or sharing yours.
  • Storing prescription opioid drugs safely.9
