Ethanol

Ethanol is a psychoactive substance that is frequently taken as a recreational drug by humans. Ethanol is classified as a depressant, although it can exhibit the properties of a stimulant at low doses.

Ethanol has very complicated pharmacodynamics. The drug acts as an agonist at GABAA receptors, an antagonist at NMDA receptors, an agonist at 5-HT3 receptors, an agonist at nicotinic acetylcholine receptors, and affects several other receptors as well.

Ethanol has several dose-dependent effects on behavior.
