Substance intoxication is a transient condition of altered consciousness and behavior associated with recent use of a substance. It is often maladaptive and impairing, but reversible. If the symptoms are severe, the term "substance intoxication delirium" may be used.
Substance intoxication may often accompany a substance use disorder (SUD); if persistent substance-related problems exist, SUD is the preferred diagnosis.
Slang terms include: getting high (generic), being stoned, cooked, or blazed (usually in reference to cannabis), and many more specific slang terms for particular intoxicants. Alcohol intoxication is graded in intensity from buzzed, to tipsy (all the way up to drunk, hammered, smashed, wasted, destroyed, shitfaced and a number of other terms).
