Inhalants
Source: National Institute on Drug Addiction
One of the most dangerous substances abused by children and teens may be found in the home. These toxic substances are collectively referred to as inhalants - breathable chemical vapors that produce mind-altering effects. A variety of common products contain substances that can be inhaled. Many people do not think that products such as spray paints, nail polish remover, hair spray, glues, and cleaning fluids present any risk of abuse, because their intoxicating effects are so totally unconnected to their intended uses. Yet, young children and adolescents are among those most likely to abuse them, and do seek them out for this purpose. Adults should store household products carefully to prevent accidental inhalation; they should also remain aware of the temptations that these dangerous substances pose to children in their homes.
National surveys, such as the National Survey on Drug Use and Health (NSDUH) and Monitoring the Future (MTF), indicate that inhalant abuse is particularly prevalent among our Nation's young people. Some young people may abuse inhalants as a substitute for alcohol because they can be obtained easily. Data suggest that inhalant abuse reaches its peak at some point during the seventh through ninth grades. According to MTF, eighth-graders regularly report the highest rates of abuse. In fact, MTF data for 2004 showed a significant increase in lifetime inhalant use among eighth-graders.
In 2002, the Nation's emergency departments reported almost 1,500 mentions of inhalant abuse by patients. Regular abuse of inhalants can cause serious damage to major organs, including the brain, liver, heart, kidneys, and lungs. However, even a single session of repeated inhalations can lead to cardiac arrest and death by altering normal heart rhythms or by preventing
enough oxygen from entering the lungs, causing suffocation.
What are Inhalants?
Inhalants are volatile substances that produce chemical vapors that can be inhaled to induce psychoactive, or mind-altering, effects. Although other abused substances can be inhaled, the term "inhalants" is used to describe a variety of substances whose main common characteristic is that they are rarely, if ever, taken by any route other than inhalation. Many young people breathe the vapors from these products hoping for a quick high, unaware of the serious health consequences of their actions.
Common household inhalant products:
- nail polish remover
- spray paint and glue
- lighter fluid
- hair and deodorant sprays
- cleaning fluid
- whipped cream canisters
Common medical/industrial inhalant products:
- gasoline
- dry cleaning fluid
- nitrous oxide (laughing gas)
- paint thinner
- paint remover
Types of Inhalants
Volatile Solvents
Volatile solvents are liquids that vaporize at room temperature. They
are found in:
- paint thinners and removers, dry cleaning fluids,
degreasers, and gasoline
- glues, correction fluids, felt-tip marker fluids,
and electronic contact cleaners
Gases
Gases include household or commercial products such as:
- butane (from lighters), propane (gas grills), and
cooling system fluids
- medical anesthetic gases, such as ether, chloroform,
halothane, and nitrous oxide
Aerosols
Aerosols are sprays that contain propellants and solvents. Some common
aerosols include:
- spray paint, hair and deodorant sprays, whipped
cream dispensers, fabric protector sprays, and vegetable
oil cooking sprays
Nitrites
Nitrites are a special class of inhalants. While other inhalants are
used to alter mood, organic nitrites are used primarily as sexual enhancers.
Organic nitrites include amyl, butyl, and cyclohexyl nitrites and other
related compounds, and are commonly known as "poppers." Amyl nitrite
was used in the past to alleviate chest pain and is sometimes used today
for diagnostic purposes in heart examinations. Most poppers contain isobutyl
nitrite or butyl nitrite. These nitrites are often sold in small brown
bottles and labeled as "video head cleaner," "room odorizer," "leather
cleaner," or "liquid aroma."
How Are Inhalants Abused?
Inhalants can be breathed in through the nose or the mouth in a variety
of ways, such as:
- Sniffing or "snorting" fumes from containers
- Spraying aerosols directly into the nose or mouth
- "Bagging," which involves sniffing or inhaling
fumes from substances sprayed or deposited inside
a plastic or paper bag
- "Huffing" from an inhalant-soaked rag stuffed in
the mouth
- Inhaling from balloons filled with nitrous oxide
Because intoxication lasts only a few minutes, abusers frequently try
to prolong the high by continuing to inhale repeatedly over the course
of several hours, a very dangerous practice.
What Are the Health Hazards Associated With Inhalants?
Animal and human research show that most inhalants are extremely toxic:
- Chronic exposure can lead to widespread and long-lasting
damage to the brain and other parts of the nervous
system. Nerve damage can be similar to that seen
in individuals with neurological diseases such as
multiple sclerosis.
- Chronic exposure can produce significant damage
to the heart, lungs, liver, and kidneys.
- Prolonged abuse can negatively affect a person's
cognition, movement, vision, and hearing.
- Highly concentrated amounts of certain inhalants
can lead to sudden sniffing death - heart failure
and death can occur within minutes of repeated inhalations.
Sudden sniffing death is particularly associated
with the abuse of butane, propane, and chemicals
in aerosols, and can result from a single session
of inhalant abuse by an otherwise healthy person.
- High concentrations of inhalants can cause death
by:
- Asphyxiation - vapors displace oxygen in
the lungs
- Suffocation - oxygen is blocked from entering
the lungs when inhaling fumes from a plastic
bag placed over the head
- Convulsions or seizures - caused by abnormal
electrical discharges in the brain
- Coma - the brain shuts down all but the most
vital functions
- Choking - from inhaling vomit prompted by
inhalant use
- Fatal injury - from accidents, such as motor
vehicle crashes, that occur while intoxicated
What Are the Effects of Inhalant Use?
Most inhalants act directly on the central nervous system (CNS) to produce
psychoactive, or mind-altering, effects. They have short-term effects
similar to anesthetics, which slow the body's functions.
- Nearly all abused inhalants, other than nitrites,
produce a pleasurable effect by depressing the CNS.
- Nitrites make the heart beat faster and produce
a sensation of heat and excitement.
- Inhaled chemicals are rapidly absorbed through
the lungs into the bloodstream and are quickly distributed
to the brain and other organs.
- Within minutes of inhaling, the user experiences
intoxication along with other effects similar to
those produced by alcohol. Alcohol-like effects include
slurred speech, muscle weakness, belligerence, apathy,
impaired judgment, euphoria, and dizziness. In addition,
users may experience lightheadedness, hallucinations,
and delusions.
- Toluene can produce headache, euphoria, giddy feelings,
and an inability to coordinate movements. Exposure
to high doses can cause confusion and delirium. Nausea
and vomiting are other common side effects.
- Successive inhalations may make users feel less
inhibited and less in control. Continued use of inhalants
in sufficient amounts can produce anesthesia, a loss
of sensation, and unconsciousness. After using inhalants
heavily, abusers may feel drowsy for several hours
and experience a lingering headache.
- Many individuals who abuse inhalants for prolonged
periods over many days report a strong need to continue
using them. Compulsive use and a mild withdrawal
syndrome can occur with long-term inhalant abuse.
Long-term inhalant abusers may exhibit other symptoms,
including weight loss, muscle weakness, disorientation,
inattentiveness, lack of coordination, irritability,
and depression.

Who Abuses Inhalants?
- People who abuse inhalants live in both urban and
rural settings. Poverty, a history of physical or
sexual abuse, poor grades, and school dropout all
are associated with inhalant abuse.
- Most inhalant abusers are younger than age 25.
One national survey indicates that about 3 percent
of U.S. children have tried inhalants by the time
they reach fourth grade.
- Eighth-graders generally abuse at higher rates
than 10th- or 12th-graders.
- In 2004, 8th-grade girls reported more inhalant
abuse than boys, while 12th-grade boys reported more
than girls.
How Can Inhalant Abuse Be Recognized?
Early identification and intervention are the best ways to stop inhalant
abuse before it causes serious health consequences. Parents, educators,
family physicians, and other health care practitioners should be alert
to the following signs of a serious inhalant abuse problem:
- Chemical odors on breath or clothing
- Paint or other stains on face, hands, or clothes
- Hidden empty spray paint or solvent containers
and chemical-soaked rags or clothing
- Drunk or disoriented appearance
- Slurred speech
- Nausea or loss of appetite
- Inattentiveness, lack of coordination, irritability,
and depression
