Diagnostic Features
Inhalant intoxication is an inhalant-related, cl inically significant mental disorder that de-
velops during, or immediately after, intended or unintended inhalation of a volatile hy-
drocarbon substance. Volatile hydrocarbons are toxic gases fr om glues, fuels, paints, and
other volatile compounds. When it is possible to do so, the particular substance involved
should be named (e.g., toluene intoxication).  Among those who do, the intoxication clears
within a few minutes to a few hours after th e exposure ends. Thus, inhalant intoxication
usually occurs in brief episodes that may recur.
