ICD-11 6C46 — Disorders due to use of stimulants including amphetamines, methamphetamine or methcathinone

Disorders due to use of stimulants including amphetamines, methamphetamine or methcathinone are characterised by the pattern and consequences of use of these substances. There is a wide array of naturally occurring and synthetically produced psychostimulants other than cocaine. The most numerous of this group are the amphetamine-type substances, including methamphetamine. Prescribed stimulants including dexamphetamine are indicated for a limited number of conditions such as for Attention Deficit Hyperactivity Disorder. Methcathinone, known in many countries as ephedrone, is a synthetic potent stimulant that is a structural analogue of methamphetamine and is related to cathinone. All these drugs have primarily psychostimulant properties and are also vasoconstrictors to a varying degree. They induce euphoria and hyperactivity as may be seen in Stimulant Intoxication. They have potent dependence-producing properties, which may lead to the diagnosis of Stimulant Dependence and Stimulant Withdrawal following the cessation of use. Several Stimulant-Induced Mental Disorders are described.

The diagnosis includes nothing.
