Heroin Overdose: Can Heroin Kill You?

Heroin is a semi-synthetic opioid that is classified as a Schedule I controlled substance.

Like all substances under this schedule, heroin has a high potential for abuse and addiction. Can you overdose on heroin, though?

Alongside addiction, overdose is one of the most dangerous risks. Data from CDC (Centers for Disease Control and Prevention) show that the number of fatal overdoses associated with heroin quadrupled over the past decade.

Can Heroin Kill You?

Heroin is a highly addictive and dangerous strong drug derived from morphine, which comes from the opium poppy plant. As an illicit drug made from poppy plants, heroin’s unpredictable potency and frequent contamination with other drugs like synthetic opioids significantly increase the risk of overdose and fatal outcomes.

What happens when you overdose on heroin often involves respiratory depression, a potentially life-threatening condition that slows heart rate and breathing to dangerous levels and should be treated as a medical emergency.

If heroin is contaminated with fentanyl or other adulterants, this may also heighten the risk of fatal heroin overdose.

How much heroin can kill you, then? 

It is estimated that 200mg of heroin is a lethal dose, although this dosage is variable due to the following contributory factors: 

  • Physiological makeup

  • Tolerance

  • Use of prescription drugs, alcohol, and illicit substances in addition to heroin

Heroin Overdose Symptoms

If someone takes too much heroin, many warning signs indicate a potential overdose. 

The most notable marker is that breathing can slow.  Monitor for the following signs of respiratory depression:

  • Slow and shallow breathing

  • Gasping for air

  • Blue lips or fingertips and lips

These symptoms indicate severe respiratory depression, where patients may stop breathing entirely. Without intervention to prevent death and restore normal breathing, fatal outcomes are likely.

There are also some other common symptoms of heroin overdose: 

  • Nausea

  • Vomiting

  • Extreme drowsiness

  • Inability to stay awake

  • Spasms

  • Seizure

  • Disorientation

  • Constipation

  • Delirium

  • Changes to mental state

  • Weak pulse

  • Low blood pressure

  • Pinpoint pupils

  • Coma

Heroin overdose can be life-threatening, so seek emergency medical attention if any of the above symptoms present in someone who has used heroin.

The signs of heroin overdose typically present roughly ten minutes after the drug is injected.   

Call 911 and request emergency medical assistance from first responders. Check that the person’s airways are unobstructed, clear their mouth if necessary, and place them into the recovery position for proper airway management.

If you have the opioid overdose reversal agent naloxone available from a pharmacy, administer one dose. If normal breathing returns after one dose, monitor the person closely. However, additional doses may be needed, as naloxone’s effects can wear off. If the person does not respond, perform rescue breathing if you are trained to do so. Nyxoid is naloxone in nasal spray form, while Prenoxad is a naloxone injectable that is injected into the upper thigh muscle or the upper arm.

Wait until the emergency responders arrive. Give them the used naloxone kit. 

Naloxone is safe and easy to use, works almost immediately, and is not addictive.

In most cases, the person overdosing on heroin will be taken to the emergency room where naloxone may be administered. If required, the person may be stabilized with IV fluids or by induced vomiting.

Heroin Overdose Statistics

CDC heroin overdose statistics show that [1]: 

  • The number of fatal heroin doses in the United States decreased by 7% from 2019 to 2020.

  • In 2020, more than 13,000 people died of a drug overdose involving heroin in the U.S.

  • Most people who died from an overdose in the United States between 1999 and 2019 were aged 35 to 54.

  • From 1999 to 2020, the rate of deadly heroin overdoses increased by a factor of seven.

  • 20% of all lethal opioid overdoses in the United States involve heroin.

  • In 2010, a rapid increase in fatal heroin overdoses saw the U.S. opioid epidemic enter a second wave. The third wave began in 2013 with a sharp increase in overdose deaths involving synthetic opioids like fentanyl.

  • From 2022 to 2023, the heroin overdose death rate decreased approximately 33%.

  • Many drug overdose deaths involving heroin also include other addictive substances like alcohol, benzodiazepines, and prescription opioid medications, creating dangerous combinations that amplify overdose risk.

Heroin Overdose Death

Heroin overdose death can occur, but this is by no means the only dangerous outcome associated with heroin abuse and repeated use of this illegal substance. 

Tolerance to heroin forms after repeated use, and physical dependence soon follows. When someone with physical dependence stops using heroin, they experience withdrawal symptoms that can be severe and uncomfortable. Sustained drug use and opioid use is liable to lead to addiction in the form of opioid use disorder or other substance use disorders.

Other potentially dangerous or life-threatening complications associated with heroin abuse include: 

  • Increased risk of HIV Infection and AIDS

  • Heightened risk of hepatitis C

  • Collapsed veins (from injecting heroin)

  • Damaged nasal tissues (from snorting heroin)

  • Lung complications (from smoking heroin)

  • Infected heart lining

  • Heart disease

  • Pneumonia

  • Liver disease

  • Kidney disease

  • Mental disorders

The skin may show track marks from injected heroin use. A doctor should evaluate anyone experiencing these complications, as many can lead to permanent harm or death if untreated. Prevention efforts and harm reduction strategies can help most people avoid these severe outcomes.

Many of these complications can be fatal.
