GHB has effects characteristic of both a depressant and a empathogenic stimulant. The drug acts on two distinct receptors in the brain: the GABAB receptor, and the GHB receptor. Its action on the GABAB receptor produces a powerful sedative, CNS inhibitory effect similar to alcohol or benzodiazepines. Through its action on the GHB receptor it exerts a excitatory effect on the brain leading to subjective effects of empathogenesis similar to MDMA. Its influence on this receptor is also responsible for the convulsions observed in GHB overdoses. GHB's effects are said to resemble a combination of alcohol and ecstasy.
