Inhalants

    A small 8g canister of nitrous oxide intended for use as a whipped cream aerating agent. Recreational drug users fill balloons with the gas, which is commonly known as "laughing gas", and inhale it for its euphoric effects.

 

Definition

    Inhalants are a broad range of drugs in the forms of gases, aerosols, or solvents which are breathed in and absorbed through the lungs. While some inhalant drugs are used for medical purposes, as in the case of nitrous oxide (a dental anaesthetic), this article focuses on the non-medical use of inhalants, as recreational drugs which are used for their intoxicating effect. Most inhalant drugs which are used non-medically are ingredients in household or industrial chemical products which are not intended to be concentrated and inhaled, including organic solvents (found in cleaning products, fast-drying glues, and nail polish removers), fuels (gasoline (petrol) and kerosene) and propellant gases such as freon and compressed hydrofluorocarbons which are used in aerosol cans such as hairspray and non-stick cooking spray. A small number of recreational inhalant drugs are pharmaceutical products which are used illicitly, such as anaesthetics (ether and nitrous oxide) and volatile anti-angina drugs (alkyl nitrites). Inhalant users tend to be people who do not have access to other drugs or alcohol, such as children, teenagers, incarcerated or institutionalized people, and marginalized individuals. The most serious inhalant abuse occurs among children and teens who "...live on the streets completely without family ties." Inhalant users inhale vapor or aerosol propellant gases using plastic bags held over the mouth or by breathing from a solvent-soaked rag or an open container. The effects of inhalants range from an alcohol-like intoxication and intense euphoria to vivid hallucinations, depending on the substance and the dosage. Some inhalant users are injured due to the harmful effects of the solvents or gases, or due to other chemicals used in the products that they are inhaling. As well, as with any recreational drug, users can be injured due to dangerous behavior while they are intoxicated, such as driving under the influence. In some cases, users have died from hypoxia (lack of oxygen), pneumonia, cardiac failure or arrest, or aspiration of vomit.


Types of Inhalants

    Solos and propellants used as inhalants are found in a range of inexpensive, legally-available household, office, industrial, and automotive products. A number of household and office products contain solvents that are used as inhalants, such as toluene and acetone. These products include correction fluids such as Liquid Paper, nail polish removers (acetone), and permanent markers (xylene). Propellant gases used as inhalants in household and office products include freon and compressed hydrofluorocarbons, which are used in various household and office products that come in aerosol spraycans, such as air freshener, computer keyboard cleaner spray (gas dusters, sometimes erroneously called "canned air"), non-stick cooking spray, and aerosol hairspray. Another household product which contains propellant gases that are used as an inhalant is aerosol whipped cream cans, which contain nitrous oxide gas.

    Industrial and automotive products also contain solvents and propellant gases that are used as inhalants. Solvents such as toluene are found in turpentine, gasoline, paint, spraypaint, and a range of quick-drying adhesives and cements (e.g., rubber cement and plastic cement). The solvent diethyl ether is used in an aerosol product called "automotive starting fluid", which mixes 20-60% diethyl ether with petroleum distillates such as hexane and heptane. Canisters of butane are used as camping fuel for small campstoves.

    Nitrite drugs such as amyl nitrite are volatile drugs which are inhaled. While they are used medically to treat heartfd diseases such as angina and to treat cyanide poisoning,[2] several nitrite drugs (nicknamed "poppers") are also used as an inhalant drug in the gay subculture and in the rave dance scene, due to their euphoric effect. While nitrite drugs are regulated by a variety of federal, state, and local regulations and legal restrictions, several nitrite products can be found in legally-available products. Amyl nitrite is available as an over-the-counter drug in some areas; butyl nitrite is sold as a room deodorizer under trade names as "RUSH" and "Locker Room"; and alkyl nitrite is an ingredient in video head cleaner or some brands of nail polish remover.



Administration

Inhalant users inhale vapors or aerosol propellant gases using plastic bags held over the mouth or by breathing from an open container of solvents, such as gasoline or paint thinner. Nitrous oxide gases from whipped cream aerosol cans and aerosol hairspray or non-stick frying spray are sprayed into plastic bags. When inhaling non-stick cooking spray or other aerosol products, some users may filter the aerosolized particles out with a rag. Some gases such as propane and butane gases are inhaled directly from the canister. Once these solvents or gases are inhaled, the extensive capillary surface of the lungs rapidly absorb the solvent or gas, and blood levels peak rapidly. The intoxication effects occur so quickly that the effects of inhalation can resemble the intensity of effects produced by intravenous injection of other psychoactive drugs

Effects

The effects of solvent intoxication can vary widely depending on the dose and what type of solvent or gas is inhaled. A person who has inhaled a small amount of rubber cement or paint thinner vapour may be impaired in a manner resembling alcohol inebriation - stimulation, a sense of euphoria and intoxication, followed by a period of depression. A person who has inhaled a larger quantity of solvents or gases, or a stronger chemical, may experience stronger effects such as distortion in perceptions of time and space, hallucinations, and emotional disturbances.

In the short term, many users experience headache, nausea and vomiting, slurred speech, loss of motor coordination, and wheezing. A characteristic "glue sniffer's rash" around the nose and mouth is sometimes seen after prolonged use. An odor of paint or solvents on clothes, skin, and breath is sometimes a sign of inhalant abuse, and paint or solvent residues can sometimes emerge in sweat.
