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 that are used in aerosol cans such as hairspray, whipped cream, and non-stick cooking spray. A small number of recreational inhalant drugs are pharmaceutical products that are used illicitly, such as anesthetics (ether and nitrous oxide) and volatile anti-angina drugs (alkyl nitrites, more commonly known as "poppers"). 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 inhaled. As with any recreational drug, users can be injured due to dangerous behavior while they are intoxicated, such as driving under the influence. Computer cleaning dusters are dangerous to inhale, because the gases expand and cool rapidly upon being sprayed. In many cases, users have died from hypoxia (lack of oxygen), pneumonia, cardiac failure or arrest, or aspiration of vomit. Examples include: Chloroform Ethyl chloride Diethyl ether Ethane and ethylene Laughing gas (nitrous oxide) Poppers (alkyl nitrites) Solvents and propellants (including propane, butane, freon, gasoline, kerosene, toluene) along with the fumes of glues containing them List of drugs which can be smoked Plants: tobacco cannabis salvia divinorum opium datura and other Solanaceae (formerly smoked to treat asthma) possibly other plants (see the section below) Substances (also not necessarily psychoactive plants smoked within them): methamphetamine crack cocaine black tar heroin phencyclidine (PCP) synthetic cannabinoids (see also: synthetic cannabis) dimethyltryptamine (DMT) 5-MeO-DMT Bufotenine DiPT Methaqualone Ethanol (alcohol) Ketamine Heroin many others, including some prescription drugs List of psychoactive plants, fungi, and animals Minimally psychoactive plants which contain mainly caffeine and theobromine: coffee tea (caffeine in tea is sometimes called theine) – also contains theanine guarana (caffeine in guarana is sometimes called guaranine) yerba mate (caffeine in yerba mate is sometimes called mateine) cocoa kola Most known psychoactive plants: cannabis: cannabinoids tobacco: nicotine and beta-carboline alkaloids coca: cocaine opium poppy: morphine, codeine, and other opiates
