Intoxicative inhalant

Intoxicative inhalants are a broad range of intoxicative drugs whose volatile vapors or gases 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 – the solvent used in contact cement and model airplane glue – are considered inhalants, but tobacco, cannabis, and crack are not, even though the latter are also inhaled (as smoke).
