A breathable chemical vapor that is abused. All abused
inhalants produce psychoactive (mind-altering) effects. Abused inhalants fall into
the following categories:
Solvents
Industrial or household solvents or solvent-containing products, including
paint thinners or removers, degreasers, dry-cleaning fluids, gasoline, and
glue
Art or office supply solvents, including correction fluids, felt-tip-marker
fluid, and electronic contact cleaners
Gases
Gases used in household or commercial products, including butane lighters
and propane tanks, whipping cream aerosols or dispensers (whippets), and
refrigerant gases
Household aerosol propellants and associated solvents in items such
as spray paints, hair or deodorant sprays, and fabric protector sprays
Medical anesthetic gases, such as ether, chloroform, halothane, and
nitrous oxide ("laughing gas")
Nitrites
Aliphatic nitrites, including cyclohexyl nitrite, an ingredient found
in room odorizers; amyl nitrite, which is used for medical purposes; and
butyl nitrite (previously used to manufacture perfumes and antifreeze),
which is now an illegal substance.
Nearly all abused inhalants produce short-term effects similar to anesthetics,
which act to slow down the body's functions. When inhaled via the nose or mouth
into the lungs in sufficient concentrations, inhalants can cause intoxicating effects.
Intoxication usually lasts only a few minutes. However, sometimes users extend this
effect for several hours by breathing in inhalants repeatedly. Initially, users
may feel slightly stimulated. Successive inhalations make them feel less inhibited
and less in control. If use continues, users can lose consciousness.
Sniffing highly concentrated amounts of the chemicals in solvents or aerosol
sprays can directly induce heart failure and death within minutes. This syndrome,
known as "sudden sniffing death," can result from a single session of inhalant use
by an otherwise healthy young person. Sudden sniffing death is particularly associated
with the abuse of butane, propane, and chemicals in aerosols.
High concentrations of inhalants also can cause death from suffocation by displacing
oxygen in the lungs and then in the central nervous system so that breathing ceases.
Deliberately inhaling from an attached paper or plastic bag or in a closed area
greatly increases the chances of suffocation. Even when using aerosols or volatile
products for their legitimate purposes (such as painting, cleaning), it is wise
to do so in a well-ventilated room or outdoors.
Chronic abuse of solvents can cause severe, long-term damage to the brain, the
liver, and the kidneys. Other harmful irreversible effects may be caused by abuse
of specific solvents.
