Heroin Overdose: Prevalence & Finding Help

Heroin users run a high risk of suffering an overdose, especially with the recent influx of street heroin that has been laced with even more powerful opioids like fentanyl and carfentanil. Overdosing on heroin can be deadly, so recognizing the signs and symptoms of an overdose is a vital part of getting help as soon as possible, whether that means calling 911 or administering naloxone. Knowing what to do in an emergency overdose situation is crucial, and may end up saving your life or the life of someone you love.

About Heroin

close-up of man holding heroin syringe and spoonHeroin is an illegal street drug in the class of drugs known as opioids. Like other drugs in this class, the use of heroin will result in opioid receptor activation throughout the brain. It is this receptor interaction that is responsible for the typical heroin high, which may include reduced sensation of pain and an overwhelming sense of wellbeing and euphoria. Despite these subjectively positive effects, heroin may also impair specific brain functions, which can result in several dangerous outcomes such as shallow or stopped breathing, slow heart rate, and very low blood pressure. All of these can be life-threatening.

Heroin can be smoked, snorted, or injected. The method of ingestion will affect the onset and duration of effects. Injecting heroin gets it to the bloodstream faster than other methods of use, so the effects come on faster and dissipate faster. This is the reason for the “rush” that many intravenous (IV) heroin users experience. Other methods of using, like smoking or snorting, do not get the drug to the blood quite as quickly. This results in a relatively slower onset of effects, but those effects might persist for a slightly longer duration.

The faster a drug like heroin reaches the brain, the greater the risk of overdose.The faster a drug like heroin reaches the brain, the greater the risk of overdose. This means that injecting heroin puts users at especially high risk of experiencing a fatal overdose. On top of this, faster methods of delivery of drugs like heroin may heighten the risk of developing an addiction. In other words, IV heroin use and the rewarding rush that it provides may be the most addictive route of use, even more than snorting or smoking it.

The Opioid Epidemic

Though heroin use rates have remained relatively stable in recent years, the rate of fatal overdoses related to heroin use has skyrocketed.1,2 There are multiple factors that may be contributing to this trend, including the increase in abuse of prescription opioid painkillers and the increase in street heroin that has been cut with other super potent opioids.

While the connection between heroin use and prescription drugs may not seem obvious, when you look a little deeper the relationship is clear. Nearly 80% of people who use heroin reported that they abused prescription opioids first.3 Prescription opioids are in the same drug class as heroin, and they can produce similar effects. These medications are prescribed to treat acute pain, but they can be highly addictive if not used exactly as prescribed by a doctor. Many people who started using prescription painkillers because of a medical condition end up developing a tolerance to the drugs, meaning they need increasing doses to get the same effects. This can result in a dangerous pattern of abuse that may lead to full-blown addiction.

Once a person is in the throes of addiction, they may no longer have medical access to these prescription medications. Opioid prescriptions are not generally intended for chronic pain conditions, so once the prescription runs out an addicted person must turn to the streets, and diverted prescription pills sold on the street are expensive. As their addiction grows, many people find that they cannot afford their prescription pill addiction anymore. This is where heroin steps in. Heroin is often much cheaper than painkillers, much easier to find on the streets, and it takes a lot less to get the same euphoric high. The progression from prescription pills to heroin is an unfortunate contributor to the current opioid epidemic.

Another major factor that has influenced the current overdose crisis is the influx of street heroin cut with extremely potent opioids like fentanyl and carfentanil. Fentanyl is 50 times more potent than heroin, and carfentanil is 100 times more potent than fentanyl.4,5 These super potent drugs have lethal doses that are miniscule compared to the lethal dose of heroin, and they are being increasingly cut into street heroin. Users who unknowingly get a batch of heroin that’s mixed with these more potent opioids face an increased risk of fatal overdose.

National Trends

About 828,000 Americans age 12 or older used heroin in 2015.6 In the same year, heroin overdose death rates hit a record high, with nearly 13,000 people dying of a heroin overdose.7 In the 5-year span between 2010 and 2015, heroin overdose death totals increased by almost 330%.7

To make matters worse, overdose rates for prescription opioid painkillers—the same drugs that may be playing a role in a resurgence in heroin use—have also sharply risen in recent years. Between 2010 and 2015, prescription opioid overdose death totals rose by more than 12,000, representing a 56% increase.7 Despite the heavy risks associated with these medications, including the risk of progressing to heroin use, U.S. sales of prescription opioids saw a 400% increase between 2010 and 2014.8

In order to beat this crisis, we must approach it from all sides. Prescribing practices must have better oversight, law enforcement must crack down on street drug dealers, and we must all educate ourselves on how to save a person’s life in the event of an opioid overdose.

What Happens During an Overdose?

Heroin affects the part of the brain that regulates breathing, and high doses of the drug can result in severe respiratory depression and death from lack of oxygen. It is important to recognize an overdose right away so that medical professionals can intervene as quickly as possible.

When trying to identify an opioid overdose situation, there are 3 primary signs that you should look for, otherwise known as the “opioid overdose triad”:9

  • Unconsciousness
  • Small, or pinpoint, pupils
  • Slow, shallow, or stopped breathing

A person suffering an overdose may also have a slow, or even stopped, heart rate.10 Heroin overdose can turn deadly very quickly. The first thing you should do if you suspect that someone may be experiencing an overdose is call 911. Naloxone is a drug that can immediately block the effects of opioids, which means it can reverse the effects of a heroin overdose.

Naloxone alone is not always sufficient for managing the full range of symptoms and consequences of heroin overdose. The person may have sustained injury to internal organs or other systems as a result of lack of oxygen and/or diminished blood flow during the overdose episode. If someone experiences an overdose, you should always seek professional medical care even if the person has been successfully revived.

What Is Narcan?

Narcan is a brand name for the nasal spray version of the drug naloxone, which is an opioid antagonist, meaning it blocks the brain’s opioid receptors. When used, naloxone quickly binds to opioid receptors, preventing heroin from activating them and effectively blocking the effects of any opioids already in the body’s system. This medication can immediately reverse an opioid overdose and save a person’s life, but as mentioned, is not an adequate standalone treatment when a person experiences an overdose.

Narcan injection for heroin overdoseThere is also an auto-injection form of naloxone, called Evzio, which gets injected into the outer thigh in emergency situations. Both Narcan and Evzio may be administered by a non-professional. The overdosing person should resume breathing and their heart rate should pick up again if the naloxone has worked. If one dose does not effectively stop the overdose (i.e., the person is still not breathing or their heart rate is still stopped), another dose may be used, but make sure you check the product’s packaging for specific instructions. CPR may also be performed to help revive a person whose heart has stopped.

Because naloxone blocks opioid receptors, administering it can cause the person to experience a rapid onset of heroin withdrawal symptoms such as nausea or tremors, which can be extremely uncomfortable but not life-threatening.

Though these effects may be unpleasant, they are not deadly, unlike a heroin overdose. Treating an overdosing person as quickly as possible will give them the best chance at survival.

Addiction Treatment

Quitting heroin for good is the only way to truly prevent an overdose. Heroin can be extremely addictive, and quitting may take some extra help to maintain abstinence. Some signs that you may be addicted to heroin include:12

  • Using for longer than you intended.
  • Taking more than you intended.
  • Lying about your heroin use.
  • Experiencing heroin cravings.
  • Wanting to stop using but being unsuccessful when you try.
  • Spending a lot of time trying to get, use, or recover from heroin.
  • Using in physically dangerous situations, like driving.
  • Developing school, work, or interpersonal problems because of your heroin use.
  • Continuing to use heroin despite related social and interpersonal problems.
  • Feeling generally unsatisfied with life.

Fighting your addiction alone can be extremely challenging. Cravings and withdrawal symptoms can cause many people in early recovery to return to heroin use simply to alleviate the discomfort. Professional treatment programs know what to expect from the heroin recovery process and can provide the psychological and medical care that you may need as you learn to live without heroin.

Quitting heroin for good is the only way to truly prevent an overdose.

Detox is the first step in heroin addiction recovery. This involves clearing all of the heroin out of your body through sustained abstinence. During this time, you may experience extremely unpleasant withdrawal symptoms, which tend to start 8 to 12 hours after the last dose.13 Heroin withdrawal symptoms tend to feel like an intense flu and can include:13

  • Fast heart rate.
  • High body temperature.
  • Chills.
  • Anxiety.
  • Insomnia.
  • Sweating or clammy skin.
  • Extreme headache.
  • Muscle and bone pain.
  • Muscle spasms.
  • Diarrhea.
  • Nausea and vomiting.
  • High blood pressure.
  • Increased breathing rate.
  • Teary eyes.
  • Runny nose.
  • Abdominal cramping.

heroin withdrawal treatment under medical supervisionHaving professional caretakers on hand as you detox can help you cope with the withdrawal period better, and they can even provide medications to help alleviate some of the symptoms. Methadone is the most frequently used medication, and it works by activating the opioid receptors in the brain to relieve cravings without the intense rush of a heroin high. Another medication that can help is buprenorphine, which also activates the same receptors as heroin but not as powerfully. Clonidine is a non-opioid medication that can address some withdrawal symptoms (such as anxiety, high blood pressure, and racing heart), but might not help much with reducing cravings.

Every person will need different medical care during heroin recovery, and professional treatment programs can provide the best care as you work toward your sobriety. Treatment programs will help you learn how to adjust to a life without heroin by working with you through individual and group therapy, so that you can strengthen your abstinence skills to resist future cravings.

Some people may need long-term maintenance medications to help them cope with cravings. This is known as medication-assisted therapy, and it can include medications such as methadone, Suboxone, and naltrexone. Naltrexone blocks the opioid receptors to prevent you from getting high if you relapse back to opioids, but it doesn’t necessarily reduce cravings. Suboxone is a combination of buprenorphine and naloxone, so it can reduce cravings and prevent heroin highs in the case of relapse. The presence of naloxone also discourages patients from using Suboxone to get high by taking more than the prescribed dose.

A treatment program can also help you set an aftercare plan. Recovery doesn’t stop when treatment ends, and some of the biggest challenges you may face will come once you’re back to living in your normal day-to-day routine. Some people find that regular therapy sessions are helpful, while others rely on support groups for aftercare help. Many people engage in a combination of several different kinds of aftercare. Your treatment program can help you find the aftercare plan that will serve you best to help you maintain sobriety long-term.
