5. GHB
GHB or gamma-Hydroxybutyric acid is a well-known neurotransmitter and a psychoactive substance, and also known as the liquid E, or liquid Gsince it has similar effects as extasy. If taken in small doses it is a stimulant, but similar to alcohol if taken in huge doses it becomes a depressant. Since it is a cheap drug (around $10 per dose), it is available and widespread, and many people use it unprepared. For making GHB, you will need GABA, sodium nitrite NaNO2, Hydrochloric acid (HCl), DCM (Dichloromethane), baking soda (NaHCO3) and distilled water.
