The chronic use of inhalants has been associated with a number of serious health problems. Sniffing glue and paint thinner causes kidney abnormalities, while sniffing the solvents toluene and trichloroethylene cause liver damage. Memory impairment, attention deficits, and diminished non-verbal intelligence have been related to the abuse of inhalants. Deaths resulting from heart failure, asphyxiation, or aspiration have occurred.
A strong need to continue using inhalants has been reported among many individuals, particularly those who abuse inhalants for prolonged periods over many days. Compulsive use and a mild withdrawal syndrome can occur with long-term inhalant abuse. Additional symptoms exhibited by long-term inhalant abusers include weight loss, muscle weakness, disorientation, inattentiveness, lack of coordination, irritability, and depression.
