inhalant
n. any of a variety of volatile substances that can be inhaled to produce intoxicating effects. Anesthetic gases (e.g., ether, chloroform, nitrous oxide), industrial solvents (e.g., toluene, gasoline, trichloroethylene, various aerosol propellants), and organic nitrites (e.g., amyl nitrite) are common inhalants. Anesthetic gases may cause asphyxiation, and chloroform has been associated with damage to the liver and kidneys. Industrial solvents are generally toxic, associated with damage to the kidneys, liver, and both central and peripheral nervous systems. Organic nitrites are less toxic but may cause arrhythmias in individuals with heart conditions. Household products, such as model airplane glue, nail polish remover, spray paint, fabric protector, cooking spray, and correction fluid, are also used as inhalants, especially by adolescents.
