Inhalants can be breathed in through the nose or mouth in a variety of ways, such as sniffing or snorting fumes from a container, spraying aerosols directly into the nose or mouth, or placing an inhalant-soaked rag in the mouth known as
huffing. Users may also inhale fumes from a balloon or a plastic or paper bag that contains an inhalant.
The intoxication produced by inhalants usually lasts just a few minutes; therefore, users often try to extend the
high by continuing to inhale repeatedly over several hours.
