Heroin

Heroin

Heroin is an opioid drug made from morphine, a natural substance taken from the seed pod of the various opium poppy plants grown in Southeast and Southwest Asia, Mexico, and Colombia. Heroin can be a white or brown powder, or a black sticky substance known as black tar heroin. Other common names for heroin include big H, horse, hell dust, and smack.

People inject, sniff, snort, or smoke heroin. Some people mix heroin with crack cocaine, a practice called speedballing.

What are the effects of heroin?

Heroin enters the brain rapidly and binds to opioid receptors on cells located in many areas, especially those involved in feelings of pain and pleasure and in controlling heart rate, sleeping, and breathing.

Prescription Opioids and Heroin

Prescription opioid pain medicines such as OxyContin® and Vicodin® have effects similar to heroin. Research suggests that misuse of these drugs may open the door to heroin use.

While prescription opioid misuse is a risk factor for starting heroin use, only a small fraction (4 percent) of people who misuse pain relievers switch to heroin. This suggests that prescription opioid misuse is just one factor leading to heroin use.

Short-Term Effects

People who use heroin report feeling a “rush” (a surge of pleasure, or euphoria). However, there are other common effects, including:

  • dry mouth
  • warm flushing of the skin
  • heavy feeling in the arms and legs
  • nausea and vomiting
  • severe itching
  • clouded mental functioning
  • going “on the nod,” a back-and-forth state of being conscious and semiconscious

Long-Term Effects include:

  • insomnia
  • collapsed veins for people who inject the drug
  • damaged tissue inside the nose for people who sniff or snort it
  • infection of the heart lining and valves
  • abscesses (swollen tissue filled with pus)
  • constipation and stomach cramping
  • liver and kidney disease
  • lung complications, including pneumonia
  • mental disorders such as depression and antisocial personality disorder
  • sexual dysfunction for men
  • irregular menstrual cycles for women

Injection Drug Use, HIV, and Hepatitis

People who inject drugs such as heroin are at high risk of contracting the HIV and hepatitis C (HCV) virus. These diseases are transmitted through contact with blood or other bodily fluids, which can occur when sharing needles or other injection drug use equipment. HCV is the most common bloodborne infection in the Unites States. HIV (and less often HCV) can also be contracted during unprotected sex, which drug use makes more likely

Other Potential Effects

Heroin often contains additives, such as sugar, starch, or powdered milk, that can clog blood vessels leading to the lungs, liver, kidneys, or brain, causing permanent damage. Also, sharing drug injection equipment and having impaired judgment from drug use can increase the risk of contracting infectious diseases such as HIV and hepatitis.

Can a person overdose on heroin?

Yes, a person can overdose on heroin. Heroin overdoses have increased in recent years. When people overdose on heroin, their breathing often slows or stops. This can decrease the amount of oxygen that reaches the brain, this can have short- and long-term mental effects and effects on the nervous system, including coma and permanent brain damage.

How can a heroin overdose be treated?

Naloxone is a medicine that can treat an opioid overdose when given right away. It works by rapidly binding to opioid receptors and blocking the effects of heroin and other opioid drugs.

Naloxone is available free as a NARCAN® Nasal Spray. Friends, family, and others in the community can use the nasal spray versions of naloxone to save someone who is overdosing.
