Can Heroin Cause Cancer? Risks, Facts & Health Impact

We are seeing a rapid growth in Heroin abuse all around the world and it is getting very concerning. Studies from the World Drug Report cite that at least 64 million people have been suffering from Heroin use from 2023-25. This is dangerous in the long run as Heroin abuse can lead to some of the most harmful side effects and diseases. Many Heroin users have faced the risks of chronic diseases like cancer in their bodies. But scientists opine that Heroin cannot cause cancer, at least directly. Can Heroin cause cancer or not? And if yes, how can drug use cause cancer?

Heroin And Its Effects

Heroin is an illicit psychoactive drug that belongs to the class of opioids. It has been banned in many countries except for a few which have decriminalized the use of Heroin in small amounts. Heroin has no medical use in general but some European countries use its other form called Diamorphine under strict medical supervision. Some of the most common outcomes of long-term Heroin use can be damage to major organs like the liver or kidneys, and intravenous clogging. Well, if you look closely, these are also the aftermath of cancer. But is this enough to understand how does Heroin cause cancer?

Side Effects Of Using Heroin

Let us first find out the harmful effects of Heroin before establishing a relation between drug abuse and chronic disease. Heroin first affects the brain, but slowly it can worsen your overall health if used for a long time. The Heroin side effects are best understood when divided into two categories.

Common Side Effects

• Sudden rush
• Sedation
• Nervous system depression
• Nausea
• Vomiting

Long-Term Side Effects

• Loss of memory
• Insomnia
• Anxiety
• Depression
• Intravenous clogging affecting blood circulation
• Damage to organs

Can Heroin Cause Cancer?

Heroin cannot cause cancer directly. A study in The Lancet Oncology says there is limited evidence to determine whether opioids can cause cancer. Other drugs have more chance to cause cancer like Cocaine compared to Heroin. But some studies show that infections like Hepatitis B/C can cause liver cancer. On top of that research conducted by the Iranian Journal of Public Health found that opioid misuse can lead to colorectal cancer. In such a case, we cannot ignore the possibility of Heroin abuse leading to various forms of cancer.

Common Types of Cancer Linked Indirectly

Colon Cancer

With a concrete study proving its existence, we have to know how can Heroin cause colon cancer. The main reason behind this possibility is that one of the side effects of Heroin is gastrointestinal issues. While initially one can only feel nauseated, longer abuse of Heroin can cause significant damage to the intestinal organs like colon. A more accurate reason is the constipation caused by Heroin use and an overdose causes inflammation in the rectum area. This malfunction can lead to the concentration of a lot of toxic adulterants in the colon and it includes carcinogenic elements that cause cancers.

Liver Cancer

Another form of cancer that Heroin can cause indirectly is liver cancer. Not one, but many aftereffects of abuse can lead to cancer in the liver. The first is Heroin causing Hepatitis B or C infection that is caused by sharing needles used while taking the drug. Overdosing on Heroin can damage the liver and cause a very dangerous condition called cirrhosis. Liver cirrhosis replaces healthy tissues of the liver with scar tissues which causes liver cancer in most cases. Besides these two, heroin bought from the streets contains heavy contamination of toxic ingredients that enter the liver and kill cells. All of these can give birth to carcinogenic properties responsible for cancer.

Kidney Cancer

There is no evidence for Heroin causing kidney cancer. Unlike the last two cases, scientists cannot prove that heroin’s side effects on the kidneys cause cancer. So let us just understand how Heroin can affect the kidneys. Again, the infected needles can cause a kidney disease called AA-Type Kidney Amyloidosis. It causes immense inflammation in the kidney that risks damage and the need to undergo dialysis treatment. Heroin abuse can also cause acute injury in the kidneys that can clearly damage the organ. These instances might cause cancer, but as of now there is no record of a case where Heroin has caused cancer in the kidneys.

Lung Cancer

To understand how can Heroin cause lung cancer, we first need to know how the drug can affect our lungs. The most common way in which Heroin can deteriorate lung health is when people snort or smoke the drug. Many have reported numerous cases of lung, mouth, and throat cancer caused by smoking heroin. It damages the airways of the lungs that make breathing extremely difficult. People often mix heroin with toxic additives that irritate our extremely sensitive lungs. The contamination of such elements in the lungs can cause COPD, indicating a huge risk of cancer.

Why Does Drug Use Cause Cancer?

Using drugs in daily life can lead to cancer not just because of indirect biological reasons. Certain practices in long-term drug abuse also pave the way to the worst medical diagnosis one can expect today. Using infected and used syringes to take the drug is one of the leading reasons behind it. Besides that, using Heroin uncontrollably weakens the immune system completely. There is nothing like “Heroin cancer” but you can get diagnosed with one for sure when you abuse Heroin and alcohol or tobacco together. Finally, Heroin use associates with unsafe sexual practices that can lead to HPV, a virus linked to cervical cancer.

Treatment and Recovery Options

Now that you know Heroin can indirectly cause cancer it’s time to stop using the drug. Get rid of the addiction and treat your Heroin withdrawals safely. Seek medical help to start your proper Heroin addiction treatment. In an inpatient treatment you will be administered medications for opioid-use-disorder (MOUD) for medical detoxification of Heroin. It mainly consists of three drugs: Suboxone, Methadone and Naltrexone. The second phase of Heroin rehab involves therapies that would help one avoid withdrawal symptoms of the drug. Holistic Therapies like meditation, outdoor activity and interaction with nature are one of the most effective ways to treat the dependence.

Conclusion

One of the positives from this discussion is that medical professionals can treat the symptoms, effects, and withdrawals associated with Heroin. As per the latest data from the World Health Organization cancer is killing approximately 27,000 people every day. Heroin use is already dangerous, but cancer caused by the illicit drug can be fatal. You must stop heroin use to live a better life.
