Inhalants are common products found right in the home and are among the most popular and deadly substances kids abuse. Inhalant abuse can result in death from the very first use. According to the annual Monitoring the Future national poll, approximately one in six children will use inhalants by eighth grade. The same report notes that inhalants are most popular with younger teens. Teens use inhalants by sniffing or "snorting" fumes from containers; spraying aerosols directly into the mouth or nose; bagging, by inhaling a substance inside a paper or plastic bag; huffing from an inhalant-soaked rag; or inhaling from balloons filled with nitrous oxide.
Inhalants are breathable chemical vapors that produce psychoactive (mind-altering) effects. Although people are exposed to volatile solvents and other inhalants in the home and in the workplace, many do not think of "inhalable" substances as drugs because most of them were never meant to be used in that way.
Young people are likely to abuse inhalants, in part, because inhalants are readily available and inexpensive. Parents should see that these substances are monitored closely so that children do not abuse them.
Inhalants fall into the following categories:
• industrial or household solvents or solvent-containing products, including paint thinners or solvents, degreasers (dry-cleaning fluids), gasoline, and glues
• art or office supply solvents, including correction fluids, felt-tip-marker fluid, and electronic contact cleaners
• 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)
• aliphatic nitrites, including cyclohexyl nitrite, which is available to the general public; amyl nitrite, which is available only by prescription; and butyl nitrite, which is now an illegal substance
Health Effects and Risks. Nearly all abused inhalants produce effects similar to anesthetics, which act to slow down the body's functions. When inhaled in sufficient concentrations, inhalants can cause intoxicating effects that can last only a few minutes or several hours if inhalants are taken repeatedly. Initially, users may feel slightly stimulated; with successive inhalations, they may feel less inhibited and less in control; finally, a user can lose consciousness.
Signs of Depression. Research shows that inhalant use is also associated with symptoms of depression. Between 2004 and 2006, an estimated 218,000 youths aged 12-17 used inhalants and also experienced depression in the past year. The same research showed that depressed teens were more than three times as likely to start using inhalants than teens with no symptoms of depression. The reverse is also true, showing that teens often started using inhalants before depression began.
Irreversible hazards. Inhalants are toxic. Chronic exposure can lead to brain damage or nerve damage similar to multiple sclerosis; damage to the heart, lungs, liver and kidneys; and prolonged abuse can affect thinking, movement, vision and hearing.
Sniffing highly concentrated amounts of the chemicals in solvents or aerosol sprays can directly induce heart failure and death. Heart failure results from the chemicals interfering with the heart's rhythm regulating system, causing the heart to stop beating. This is especially common from the abuse of fluorocarbons and butane-type gases. High concentrations of inhalants also cause death from asphyxiation, suffocation, convulsions or seizures, coma, choking or fatal injury from accidents while intoxicated. Other irreversible effects caused by inhaling specific solvents are:
• Hearing loss - toluene (paint sprays, glues, dewaxers) and trichloroethylene (cleaning fluids, correction fluids)
• Peripheral neuropathies or limb spasms - hexane (glues, gasoline) and nitrous oxide (whipping cream, gas cylinders)
• Central nervous system or brain damage - toluene (paint sprays, glues, dewaxers)
• Bone marrow damage - benzene (gasoline)
• Liver and kidney damage - toluene- containing substances and chlorinated hydrocarbons (correction fluids, dry- cleaning fluids)
• Blood oxygen depletion - organic nitrites ("poppers," "bold," and "rush") and methylene chloride (varnish removers, paint thinners)
