Topic Overview

Inhalants are substances that produce chemical vapors that, when inhaled, result in mind-altering effects. The term inhalant is used because these substances are rarely, if ever, used by any other means. These substances are common household, industrial, or medical products. But most people do not think of them as drugs, because they are not meant to be used in that way.

Inhalants commonly used include:

• Solvents (such as paint thinners and degreasers), gasoline, glues, and office supplies (such as correction fluids, felt-tip markers, and electronics cleaners).
• Gases (such as household products including aerosol computer cleaners, butane lighters, whipping cream aerosols (whippets), spray paints, hair or deodorant sprays, vegetable oil sprays, and fabric protector sprays).
• Nitrites (such as a prescription medicine called amyl nitrite). An illegal form of amyl nitrite, called poppers or snappers, is often packaged and sold in small bottles. Common room odorizers also contain nitrites that can be inhaled.

When inhalants are breathed, they cause alcohol-like effects: slurred speech, lack of coordination, and dizziness. The person can become lightheaded and may have hallucinations and delusions. The effects last only a few minutes. After heavy use of an inhalant, the person may have a headache and feel drowsy for several hours. The person who inhales repeatedly over several hours can lose consciousness and die.

Aerosols can be sprayed directly into the nose or mouth. Nitrous oxide can be inhaled directly from balloons. Several terms are used for the way inhalants are breathed into the lungs, including:

• Sniffing or snorting, when fumes are inhaled from a container.
• Bagging, when fumes are inhaled from substances sprayed or deposited inside a plastic bag.
• Huffing, when a soaked rag is placed in the mouth or held to the face for inhalation.

Long-term health problems, such as brain, liver, kidney, blood, or bone marrow damage, can occur from inhaling some substances. Long-term use of inhalants also causes:

• Weight loss.
• Muscle weakness and lack of coordination.
• Disorientation and inattentiveness.
• Irritability and depression.

Inhalants are often not detected with urine or blood drug screening tests, because they have usually been eliminated from the body by the time the test is done.

• Empty containers or discarded soaked rags or clothing hidden in the trash
