Heroin Addiction, Withdrawal, And Treatment

Heroin is an opioid drug that causes effects like euphoria, sedation and slowed breathing. It’s highly addictive and can lead to opioid use disorder (OUD) after just a few uses. 

The types of heroin include: 

  • Black tar heroin, which looks like a sticky black- to grey rock
  • Refined street heroin, which looks like coarse ivory or pink powder
  • Unrefined street heroin, which looks like a sandy-textured clumpy brown powder 
  • Southeast Asian heroin, which looks like a fine white powder that you can dissolve in water
  • Southwest Asian heroin, which looks like a coarse brown powder that resists getting wet 

All of these types of heroin cause addiction at a high rate. That’s regardless of whether you smoke it, inject it or snort it nasally.

Around 23% of people who use heroin become dependent on it, making heroin one of the most addictive drugs.

Many people develop heroin addiction after receiving a prescription for an opioid pain medication. Heroin has similar effects to these medications and prevents you from withdrawing from them. 

The problem is, heroin is very addictive and it’s easy to overdose on it. In large doses, heroin causes your breathing to slow, which can lead to coma and death. 

Heroin addiction increases your risk of overdose and death. If you suspect that you’re living with heroin addiction, then you should seek help. 

What Are the Effects of Heroin?

Heroin has many short-term and long-term effects on your mind and body. Its most common effects are tolerance, addiction and withdrawal. 

The length and intensity of heroin’s effects depend on factors like: 

  • Your age, physical health, and mental health
  • Your typical heroin dose
  • The length of time you used heroin
  • Whether you use other drugs or substances 

The effects may be stronger and take longer to wear off if you’re older, have health problems, use large doses of heroin, or have used heroin for a long time. 

Effects of Heroin Withdrawal

When you use heroin repeatedly, you can develop a dependence on it. If you’re dependent, then you’ll experience withdrawal when you stop using heroin. 

The effects of heroin withdrawal include: 

  • Fever
  • Heroin cravings
  • Insomnia
  • Mood changes, including depression, anxiety, or irritability
  • Muscle pain
  • Nausea and stomach pain
  • Runny nose
  • Sweating
  • Vomiting and diarrhea 

Your risk of relapse is at its highest when you’re experiencing withdrawal. If you have withdrawal when you stop using heroin, you should seek medical detox help. 

Effects of Heroin Overdose 

When you use too much heroin or mix it with the wrong substances, it can lead to a heroin overdose. A heroin overdose is a medical emergency and it can lead to death. Call 911 right away if someone around you is having a heroin overdose. 

The effects of a heroin overdose include: 

  • Blue skin, nails, or lips
  • Delirium
  • Unconsciousness
  • Pinpoint pupils
  • Slow breathing
  • Slow pulse

A heroin overdose can cause death very quickly. If you have Narcan on hand, administer it using an automatic injector or nasal spray, then call 911. This can reverse the overdose and buy some time until emergency medical services arrive. 

What is Heroin Addiction?

Heroin addiction is the most common long-term effect of heroin use. 

When you use heroin in large amounts or repeatedly, your body becomes used to its effects. This leads to tolerance, or the need to take increasingly larger doses. 

In turn, that causes addiction. When you have an addiction to heroin, you have to keep using or you’ll experience withdrawal. 

Withdrawal is very uncomfortable and it’s what keeps most heroin users from seeking help. You are most likely to relapse during a withdrawal episode. 

Addiction to heroin leads to a never-ending cycle of using heroin to avoid withdrawal. Your social life, finances, ability to keep a job, and quality of life are commonly affected. 

Heroin and Other Drugs

Most people who use heroin use other drugs as well. Heroin is dangerous to mix with other drugs because it has health interactions with many of them.

It’s particularly dangerous to mix heroin with: 

  • Opioid drugs
  • Benzodiazepine drugs
  • Fentanyl
  • Stimulant drugs
  • Alcohol
  • Certain over-the-counter medications 

Heroin and Opioid Pain Medications

Heroin is an opioid drug, which makes it dangerous to mix with narcotic pain medications. You should never mix heroin with opioid medications. 

That includes these prescription opioids: 

  • Codeine
  • Hydrocodone
  • Morphine
  • Oxycodone
  • Oxymorphone
  • Tramadol

When you mix opioid medications with heroin, you increase the risk of overdosing on both. The result can be respiratory depression or a slowing of your breathing that can lead to coma and death. 

Heroin and Benzodiazepine Medications

Benzodiazepines are medications that treat anxiety, insomnia, and seizures. Benzos and heroin have a severe interaction and you shouldn’t take them together. 

Some common benzos include: 

  • Alprazolam
  • Clonazepam
  • Diazepam

Taking these medications with heroin can cause death. Opioids and benzos both affect your breathing, and when you take them together, the chance of respiratory depression is much stronger. This can cause coma and death. 

Heroin and Fentanyl

The combination of heroin and fentanyl is one of the most dangerous drug combinations. 

Fentanyl by itself is 100 times stronger than morphine, and 100 times deadlier. When you mix fentanyl with heroin or other opioids, the risk of overdose and death is very high. 

You may not even know that you’re using fentanyl, since it’s a common cutting agent in street heroin and street pills. 

Heroin and Stimulants

It’s common to mix heroin with stimulants like meth or cocaine, but there’s a serious risk involved. 

People take heroin and stimulants together to increase the effects of both drugs. It’s more common to use heroin and cocaine together, a combo that’s known as a speedball

This combination can increase your risk of overdose by stimulating your nervous system too much. Stimulants make your body crave more oxygen, while depressants like heroin make your breathing slow down. 

The resulting strain on your body can lead to an overdose at doses that you wouldn’t expect. 

Heroin and Alcohol

Heroin and alcohol is an unsafe combination that can cause brain damage and much worse. 

When you drink alcohol while using heroin, your risk of addiction and overdose increases significantly. You may experience tremors, trouble with movement and even seizures. 

This is the result of your respiratory system being suppressed too much. Alcohol and heroin both slow breathing, which deprives your body of oxygen. You can experience permanent brain damage and even death. 

Heroin and Other Medications

Heroin interacts with many medications, especially medications that have a sedating effect. You should not take heroin while using: 

  • Antidepressants such as Cymbalta or Lexapro
  • Antipsychotics such as Seroquel
  • Blood pressure medications such as clonidine 
  • Medication-assisted treatment drugs such as Suboxone or Subutex
  • Muscle relaxers such as Flexeril 
  • Nerve pain drugs such as Lyrica or gabapentin

You have an increased risk of side effects and death if you mix heroin with these medications. This is not a complete list of all the medications to avoid while using heroin. Talk to your doctor or pharmacist about medications to avoid.

What Are Statistics on Heroin Addiction?

In 2018, the Centers for Disease Control and Prevention (CDC) reported that: 

  • 15,000 people died from heroin overdoses, or 5 deaths per 100,000 Americans. 
  • Heroin overdose deaths increased in the West, with the highest rate in Vermont at 12.5 deaths per 100,000 people. 
  • The number of heroin-related overdose deaths was 7 times higher in 2018 than in 1999. 
  • Almost 33% of all opioid deaths were caused by heroin.
