Substance intoxication

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).


Examples (and ICD-10 code) include:

  • F10.0 alcohol intoxication (drunk)
  • F11.0 opioid intoxication
  • F12.0 cannabinoid intoxication (high)
  • F13.0 sedative and hypnotic intoxication (see benzodiazepine overdose and barbiturate overdose)
  • F14.0 cocaine intoxication
  • F15.0 caffeine intoxication
  • F16.0 hallucinogen intoxication (See for example Lysergic acid diethylamide effects)
  • F17.0 tobacco intoxication (See for example Nicotine poisoning)

    Contact high

    The term contact high is sometimes used to describe intoxication without direct administration, either by second-hand smoke (as with cannabis), or by placebo in the presence of others who are intoxicated.
