Opioid and Heroin


Opioids are a class of drugs that include the illegal drug heroin, synthetic opioids such as fentanyl, and pain relievers such as oxycodone (OxyContin®), hydrocodone (Vicodin®), codeine, morphine and others available legally by prescription.

Opioid pain relievers are generally safe when taken for a short time and as prescribed by a doctor, but because they produce euphoria in addition to pain relief, they can be misused. Regular use, even as prescribed by a doctor, can lead to dependence. When misused, opioid pain relievers can lead to overdose incidents and deaths.


Heroin is an opioid drug made from morphine, a natural substance taken from the seed pod of various opium poppy plants. Heroin comes in many forms, including white or brown powder, or a sticky black substance known as black tar heroin.

Heroin enters the brain rapidly and binds to opioid receptors on cells located in many areas, especially those involved with feelings of pain and pleasure. It can also affect a person's heart rate, sleeping and breathing. 

Research suggests that the misuse of prescription opioid pain medicine is a risk factor for starting heroin use. Heroin use can lead to addiction, a form of substance abuse disorder. A person can overdose on heroin. 

Drug Overdose Overview

Overdoses occur when a person takes more than the medically recommended dose of a drug. Generally, in an overdose, the therapeutic effects of the drug are experienced at a heightened level. Side effects can become more pronounced, and other effects not seen with normal use may take place. Some overdoses can worsen a person's chronic disease, such as asthma.

Overdose symptoms include:

  • Vital sign (temperature, pulse rate, respiratory rate, blood pressure) values can be increased, decreased, or absent.
  • Sleepiness, confusion, and coma.
  • Skin that is cool and sweaty, or hot and dry.
  • Chest pains.
  • Abdominal pain, nausea, vomiting and diarrhea.

If an overdose is expected, seek medical care from your doctor, your local poison center, or the emergency department of your local hospital. Specific and accurate information including the name of the drug, the amount of the drug ingested, and the time the drug was taken will be needed to help identify symptoms.
