Inhalants are sometimes called “Deliriants,” in that they may produce delirium. Delirium is usually a brief state characterized by incoherent excitement, confused speech, restlessness and possible hallucinations.

Inhalants vary widely in terms of the chemical involved and the specific effects produced. Depending on the nature of the particular Inhalant, the effects produced may be similar to those of CNS Stimulants, Depressants or Hallucinogens.

There are three major subcategories of Inhalants

• Volatile Solvents
• Aerosols
• Anesthetic Gases
