Inhalant abuse is hard to talk about because of the confusing terms used to describe it.
Substances such as glue, gasoline, anesthetic gases and nitrites have all been discussed under the title of inhalant abuse. Volatile nitrites function as vasodilators. They dilate blood vessels and increase heart rate. Butyl nitrite is marketed in room fresheners. Anesthetic gases produce the loss of sensations and possibly loss of consciousness that is required for some dental and surgical procedures.
