""Louisiana prohibits the sale, transfer, or possession of model glue and inhalable toluene substances to minors. In Ohio, it is illegal to inhale certain compounds for intoxication—a common, general prohibition other states have enacted. Some states draw their prohibitions more narrowly... In Massachusetts, retailers must ask minors for identification before selling them glue or cement that contains a solvent that can release toxic vapors." Propellant gases
"New Jersey... prohibits selling or offering to sell minors products containing chlorofluorocarbon that is used in refrigerant." Poppers
The sale of alkyl nitrite-based poppers was banned in Canada in 2013. Although not considered a narcotic and not illegal to possess or use, they are considered a drug. Sales that are not authorized can now be punished with fines and prison. Since 2007, reformulated poppers containing isopropyl nitrite are sold in Europe because only isobutyl nitrite is prohibited. In France, the sale of products containing butyl nitrite, pentyl nitrite, or isomers thereof, has been prohibited since 1990 on grounds of danger to consumers. In 2007, the government extended this prohibition to all alkyl nitrites that were not authorized for sale as drugs.
Solvents have many potential risks in common, including pneumonia, cardiac failure or arrest, and aspiration of vomit. The inhaling of some solvents can cause hearing loss, limb spasms, and damage to the central nervous system and brain. Serious but potentially reversible effects include liver and kidney damage and blood-oxygen depletion. Death from inhalants is generally caused by a very high concentration of fumes. Deliberately inhaling solvents from an attached paper or plastic bag or in a closed area greatly increases the chances of suffocation. Brain damage is typically seen with chronic long-term use as opposed to short-term exposure. Parkinsonism (see: Signs and symptoms of Parkinsons disease) has been associated with huffing. Female inhalant users who are pregnant may have adverse effects on the fetus, and the baby may be smaller when it is born and may need additional health care (similar to those seen with alcohol – fetal alcohol syndrome). There is some evidence of birth defects and disabilities in babies born to women who sniffed solvents such as gasoline. In the short term, death from solvent use occurs most commonly from aspiration of vomit while unconscious or from a combination of respiratory depression and hypoxia, the second cause being especially a risk with heavier-than-air vapors such as butane or gasoline vapor. Deaths typically occur from complications related to excessive sedation and vomiting. Actual overdose from the drug does occur, however, and inhaled solvent use is statistically more likely to result in life-threatening respiratory depression than intravenous use of opioids such as heroin.
