Just about anything in an aerosol can be mind altering if inhaled deeply. Huffing also damages the brain, affecting memory, concentration, hearing, and coordination and chronic use of inhalants can also cause heart, lung, liver, and kidney damage.
Aerosol spray is a type of dispensing system which creates an aerosol mist of liquid particles. This is used with a can or bottle that contains a liquid under pressure. When the container's valve is opened, the liquid is forced out of a small hole and emerges as an aerosol or mist. As gas expands to drive out the payload, only some propellant evaporates inside the can to maintain an even pressure. Outside the can, the droplets of propellant evaporate rapidly, leaving the payload suspended as very fine particles or droplets. Typical liquids dispensed in this way are insecticides, deodorants and paints. An atomizer is a similar device that is pressurised by a hand-operated pump rather than by stored gas.
The concepts of aerosol probably go as far back as 1790. The first aerosol spray can patent was granted in Oslo in 1926 to Erik Rotheim, a Norwegian chemical engineer, and a United States patent was granted for the invention in 1931. The patent rights were sold to a United States company for 100,000 Norwegian kroner. The Norwegian Postal Service, Posten Norge, celebrated the invention by issuing a stamp in 1998. Nephropathy
Intoxicative inhalants are a broad range of intoxicative drugs whose volatile vapors are taken in via the nose and trachea. They are taken by room temperature volatilization or from a pressurized container (e.g., nitrous oxide), and do not include drugs that are sniffed after burning or heating. For example, amyl nitrite and toluene are considered inhalants, but tobacco, marijuana, and crack are not, even though the latter are also inhaled.
While some inhalant drugs are used for medical purposes, as in the case of nitrous oxide (a dental anxiolytic), this article focuses on inhalant abuse as recreational drugs that are used for their intoxicating effect. Inhaling volatile substances because of their intoxicating effect is called huffing.
Substance abuse, also known as drug abuse, is a patterned use of a substance (drug) in which the user consumes the substance in amounts or with methods which are harmful to themselves or others.
The term "drug abuse" does not exclude dependency, but is otherwise used in a similar manner in nonmedical contexts. The terms have a huge range of definitions related to taking a psychoactive drug or performance enhancing drug for a non-therapeutic or non-medical effect. All of these definitions imply a negative judgment of the drug use in question (compare with the term responsible drug use for alternative views). Some of the drugs most often associated with this term include alcohol, substituted amphetamines, barbiturates, benzodiazepines (particularly alprazolam, temazepam, diazepam and clonazepam), cocaine, methaqualone, and opioids. Use of these drugs may lead to criminal penalty in addition to possible physical, social, and psychological harm, both strongly depending on local jurisdiction. There are many cases in which criminal or antisocial behavior occur when the person is under the influence of a drug. Long term personality changes in individuals may occur as well. Other definitions of drug abuse fall into four main categories: public health definitions, mass communication and vernacular usage, medical definitions, and political and criminal justice definitions. Substance abuse is prevalent with an estimated 120 million users of hard drugs such as cocaine, heroin, and other synthetic drugs.]citation needed[
Gas duster, also mistakenly known as canned air or compressed air, is a product used for cleaning electronic equipment and other sensitive devices that cannot be cleaned using water. Despite the name "canned air," the cans actually contain gases that are much easier to compress into liquids, such as 1,1-difluoroethane, 1,1,1-trifluoroethane, or 1,1,1,2-tetrafluoroethane. Hydrocarbons, like butane, were often used in the past, but their flammable nature forced manufacturers to use fluorocarbons. Referring to the contents as "air", compressed or otherwise, could be dangerously, even fatally misleading, if someone regards the contents as being safe to breathe in concentrated form. Such terms should not be used.
