Sudden Sniffing Death Syndrome: What it is and Why Inhalant Abuse is So Dangerous

Sudden sniffing death syndrome is one of the most serious risks associated with inhalant abuse, since it can happen quickly and without warning. It also isn’t only exclusive to someone with a history of long-term inhalant use and can happen even after the very first time someone attempts huffing.

This is part of what makes inhalants so dangerous. Many household products and items that are commonly misused as inhalants are not illicit street drugs. They are common household items like aerosol sprays, spray paints, deodorant, cleaning solutions, correction fluid, paint thinners, refrigerants, butane, propane, and other volatile substances.

Because of this familiarity, people, particularly youth, may not fully appreciate the degree of danger they present.

What is Sudden Sniffing Death Syndrome?

Sudden sniffing death syndrome (SSDS), sometimes simply called sudden sniffing death, refers to an unexpected death resulting from the use of inhalants, occurring either during or immediately following use.[1] Inhalants in this case are substances that emit vapors that cause intoxication when inhaled, including everyday items found in the average home, school, or workplace.[2]

People who misuse inhalants generally do so by directly sniffing vapor from a container, spraying aerosol into their mouths, inhaling vapors from rags, or breathing vapors from a plastic bag (a practice called huffing). Some people also misuse nitrous oxide contained in whipped cream chargers, known as “whippets.”

The effects of using inhalants are short-lived; the danger presented is immediate. Sudden death resulting from the misuse of volatile solvents happens due to respiratory failure or arrest, obstruction of the airway, or heart arrhythmias.[3]

What Causes Sudden Sniffing Death?

Sudden sniffing death syndrome is primarily caused by specific ways that various chemicals affect a person’s heart. Many inhalants are volatile solvents or hydrocarbons, which means they easily evaporate into gas or vapor and can be breathed in.

Inhaling volatile solvents can sensitize the heart to epinephrine (adrenaline).[3] When someone uses inhalants and then feels fear or excitement, startles, or runs, that adrenaline rush could initiate an arrhythmia. In some cases, that arrhythmia can be fatal and lead to cardiac arrest.

Deaths from inhalant use can also occur due to other factors:

• Suffocation when a plastic bag or enclosed area is used to breathe in gases or vapors
• Oxygen depletion when vapors displace breathable air
• Choking after loss of consciousness
• Injury from falls, burns, car accidents, and other accidents while intoxicated
• Respiratory depression, meaning shallow breathing that results in excessive carbon dioxide buildup and lack of oxygen

There is no safe way to use inhalants, and someone can suffer sudden sniffing death whether it’s their first time or if they have a long history of it.

What Products Are Linked to Inhalant Abuse?

Inhalant abuse can involve several types of household, commercial, or medical products. Common examples include:

• Aerosol sprays, including deodorant, hair spray, air fresheners, and computer dusters
• Solvents, including paint thinners, cleaning fluids, correction fluid, and nail polish remover
• Gases, including butane, propane, refrigerants, and nitrous oxide
• Propellants used in aerosol products
• Products containing toluene, which may be found in spray paint, glue, and certain solvents

Inhalants are often easy to buy or already available in everyday settings.[4] That easy access can make prevention harder, especially for adolescents. A product being legal, inexpensive, or common does not make it safe. These substances were not made to be inhaled into the body for intoxication.

Why Young People Are at Higher Risk

Inhalant abuse is particularly alarming among teenagers, since the products are easily available, the high occurs quickly, and many teens do not realize how close to death they can come. According to the National Institute on Drug Abuse (NIDA), the majority of inhalant use happens among younger teens as opposed to older teens.[5]

While this does not mean all teens are misusing inhalants, it means parents, teachers, and healthcare professionals need to pay closer attention to the early warning signs. The Consumer Product Safety Commission warns that inhalant abuse often starts during the middle school years and that aerosol duster products have caused both fatalities and injuries.[6] What may seem to be nothing more than experimental sniffing can result in a real risk of heart failure, suffocation, permanent brain damage, or fatal injury.

Warning Signs of Huffing or Inhalant Use

Huffing or inhalant use may be harder to identify due to short-lived intoxication; however, there are several signs that could indicate someone is improperly using common household products.

Some of these signs include:

• Chemical odor on breath, skin, or clothes, or a chemical odor in their room
• Dizziness, slurred speech, disorientation, or lack of balance and coordination
• Paint or stains on the face, hands, clothing, or belongings
• Hidden aerosol cans, whipped cream chargers, rags, or plastic bags
• Skin redness or irritation near the nostrils and mouth
• Mood swings, secrecy, or withdrawal
• Declining academic or work performance
• Headaches, nausea, fatigue, or nosebleeds

Many of these symptoms can have multiple explanations. When the above symptoms appear along with missing household products, chemical smells, or hidden cans, ask questions directly.

Short-Term and Long-Term Effects of Inhalant Abuse

Inhalant misuse can lead to dizziness, euphoria, slurred speech, impaired judgment, hallucinations, and stomach upset or nausea while under the influence. Misuse of inhalants also increases a person’s chance of being injured through accidents or unsafe decisions.

However, the long-term effects of inhalant misuse can be much more damaging. Prolonged misuse of inhalants can result in irreparable damage to the brain, other organs, and the central nervous system.[7] Misuse of certain inhalants over an extended period of time can also result in liver damage, kidney damage, hearing loss, movement problems, memory loss, and mental health issues.

Chronic users can also develop a dependency on inhaling products. Although inhalants are less frequently mentioned in terms of addictive potential when compared to alcohol, stimulants, or opioids, inhalant use can still become a substance-related problem requiring professional assistance.

What to Do in an Emergency

If someone collapses, has trouble breathing, loses consciousness, experiences chest pains, or seems severely confused after huffing, call 911 immediately.

Do not scare, intimidate, or startle someone who is currently intoxicated from inhalants unless immediate danger requires action. Since adrenaline plays a role in cardiac arrhythmias, attempt to keep the person calm. If it is safe to do so, move the person away from fumes, keep them still, and wait until emergency medical personnel arrive.

If you know which product was used, provide that information to first responders. Knowing the name of the product will aid emergency medical staff and toxicologists in identifying which chemicals were involved.

How Can Sudden Sniffing Death Syndrome and Inhalant Abuse Be Prevented?

Preventing SSDS and inhalant misuse happens when education and access control combine with early intervention. The purpose behind educating young people about the dangers of huffing is not to frighten them, but to inform them of the risks associated with huffing.

For prevention to be successful, education should include:

• Open communication about the dangers associated with huffing household products, including cardiac arrest and death.
• Storing household products containing hazardous materials safely. This includes keeping aerosol sprays, solvents, paint thinners, butane, propane, and cleaning solutions inaccessible to children.
• Monitoring missing products. Pay attention to empty aerosol cans, computer dusters, or correction fluid that are being used at rates higher than normal.
• Avoid shame-based conversations. Instead, create open and non-threatening dialogue when discussing concerns related to inhalant misuse.
• Consider asking about anxiety, depression, or isolation, since some youth experience these emotions as a contributing factor for experimenting with inhalants.
• Provide professional help early if necessary. Many times, young people who are misusing inhalants are hesitant to seek help due to fear or shame. Providing supportive services earlier rather than later gives them an opportunity to avoid escalating their behavior.

A young person who has been huffing may already feel embarrassed or afraid once they realize that others know what they did. A calm, concerned response will improve the likelihood of them expressing themselves honestly and accepting help.

When Inhalant Use Points to a Bigger Concern

Inhalant use might seem like just a little experimentation at first. However, the dangers associated with using inhalants cannot be ignored. There is a risk of serious harm or death each time a product is inhaled. Inhalant use can also be indicative of larger issues, such as underlying anxiety or depression, traumatic experiences, pressures from peers, stress in the home environment, or other types of substance use disorders.

When talking to your loved one, there doesn’t have to be a “perfect” approach. Just a consistent message can be helpful. For example: “I’m not here to shame you. I’m concerned because this behavior is dangerous, and I want to help.”
