The Dangers and Effects of Snorting Heroin

Heroin is not only extremely addictive, but it is also incredibly dangerous.¹ While some people may assume that avoiding injection use and only snorting heroin is safe, there is no safe way to use this illegal opioid.^1,2

Any use of heroin, including snorting, may result in a life-threatening heroin overdose, the primary signs of which include:³

• Tiny pupils.
• Loss of consciousness.
• Problems breathing.

Other risks of snorting heroin include dependence, addiction, and numerous health problems.⁴

Short-Term Effects of Snorting Heroin

Snorting heroin will produce a very rapid high (euphoria) with effects that include:⁴

• Flushing/warmth of the skin.
• Heaviness in the extremities.
• Inability to think clearly.
• Itchiness.
• Nausea.
• Vomiting.
• Dry mouth.
• Nodding off (falling in and out of consciousness).

Long-Term Effects of Snorting Heroin

Snorting heroin may lead to a number of troubling long-term effects, including:^5,6

• Chronic runny nose.
• Nasal pain.
• Problems swallowing.
• Nasal tissue damage and ulceration.
• Holes in the nasal septum (the tissue separating the nostrils).

Other long-term effects of heroin that may occur with any method of use include:^4,7

• Insomnia.
• Severe constipation.
• Depression and other mental health disorders.
• Lung complications, including pneumonia.
• Irregular menstrual cycles (women)
• Impaired sexual functioning (men).
• Opioid dependence.
• Opioid use disorder (addiction).

Snorting vs. Injecting Heroin

Some individuals may snort heroin, believing that is a safer alternative to injecting the drug.^1,2 It is true that injecting heroin or any other illicit drug, for that matter, does have some very serious unique risks, including:⁷

• Scarred veins.
• Collapsed veins.
• Bacterial infections of the heart valves.
• Abscesses.
• Clogged blood vessels.
• Transmission of bloodborne diseases, such as HIV and HCV, through needle-sharing.

However, even snorting heroin has risks, including the risks of addiction, infection, and life-threatening overdose.^7,8

Also, arguably one of the most frightening risks of injection use, HIV and other infectious disease transmission, while lower, is still a risk for intranasal users. Heroin use decreases inhibition and impairs judgment, often resulting in risky sexual behaviors (such as unprotected sex), which increases a person’s risk for getting HIV or other infectious diseases.^4,11

Opioid overdoses have been growing significantly since the appearance of fentanyl and its analogues into the heroin market across the United States.¹² It is not possible to detect fentanyl in heroin by smelling, tasting, or looking at the heroin powder, and heroin users may snort fentanyl-laced powder without realizing it.¹³ Unfortunately, it takes an extremely small amount of fentanyl to cause overdose and death,¹³ and with the ever-growing amount of this synthetic opioid in heroin all across the country,¹² users put themselves at risk of overdose every time they snort heroin.
