Heroin achieves this high by binding to opioid receptors in the brain, which then immediately release an unnatural amount of dopamine, causing feelings of pain relief and euphoria or a dream-like state. Often users go in and out of consciousness because breathing is slowed down so much. This is also what makes overdosing so common and possible for even first timers.

The short-term effects:

  • Euphoria
  • Dry mouth
  • Pinpoint pupils
  • Flushed or red skin
  • Itching
  • Nausea or vomiting
  • Analgesia
  • Slowed breathing and heart rate

Effects of long-term use:

  • Collapsed veins
  • Abscesses (swollen tissue with pus)
  • Infection of the lining and valves in the heart
  • Constipation and stomach cramps
  • Liver or kidney disease; pneumonia
  • Depression
  • Sexual dysfunction and disruption of menstrual cycle in females
  • Destruction of white matter in the brain where behavior, decisions, and learning happen
  • Reduced immune system function leading to increased infections
  • Sleep apnea
  • Hemorrhoids or anal bleeding

Use during pregnancy may lead to miscarriage, low birth weight, neonatal abstinence syndrome.

Other potential health issues: Risk of HIV, hepatitis, and other infectious diseases from shared needles.

Withdrawal symptoms can begin as quickly as 6 to 12 hours after the last dose, but usually peak within 1 to 3 days, and gradually decrease over 5 to 7 days. However, some users experience weeks or months of withdrawal symptoms.

People addicted to heroin are likely to experience discomfort when stopping use, but withdrawal symptoms can also appear following heavy use. Physically, heroin withdrawal may feel like having the flu. People often experience;

  • nausea
  • diarrhea
  • runny nose
  • achiness
  • tremors
  • fatigue
  • chills
  • sweats

More severe symptoms can include;

  • difficulty breathing
  • depression
  • anxiety
  • insomnia.

Following acute heroin withdrawal, people typically go through a period in which they experience strong drug cravings and may feel less than well. During this period, there is an increased risk of relapse, so additional treatments are important to help ensure long-term recovery. Such treatments can include behavioral therapies and pharmacological treatments.


The National Institute on Drug Abuse reports that medications such as methadone, buprenorphine, and naltrexone have been shown to increase the effectiveness of treatment programs in the long-term.


Behavioral approaches such as cognitive-behavioral therapy and contingency management are two types of therapy that are often used to treat heroin addiction. Cognitive-behavioral therapy focuses on helping people change thoughts and behaviors that contribute to drug use, where contingency management rewards people for staying drug-free with vouchers that can then be exchanged for desired rewards. 


Treatment for heroin use often combines these behavioral approaches with medication.


Unintentional heroin overdoses increased dramatically from 2006 to 2016. Mixing synthetic opioids, including fentanyl, with heroin resulted in a spike in deaths from 3,036 in 2010, when most cases didn’t involve a synthetic opioid, to 15,469 in 2016, when about 37 percent did.
