How it is used

 

The fumes from organic solvents may simply be inhaled from their containers. A liquid solvent may also be poured or sprayed on an absorbent material to increase the release of fumes. Users often try to concentrate the fumes by putting the solvent in a paper or plastic bag or a rubber balloon, and then holding the open end over the mouth and nose.

Capsules containing amyl nitrite are crushed and held beneath the nose. Butyl nitrite may be inhaled in its container, or, like organic solvents, applied to absorbent cloth or paper.

Nitrous oxide may be inhaled through a mask from a tank of the compressed gas or directly from a punctured whippet. The nozzle of a whipped-cream container can also be depressed in such a way that only the NOS is discharged.
