Source: The lab.

Legal code: Legal by prescription.

History: In the mid-1800s, scientists synthesized chloral hydrate, the first chemical sedative. The first barbiturate was synthesized in 1903.

Effects: Users report a decrease in anxiety level and a sense of relaxation and calm. But unexpected, unpredictable opposite effects, such as increased anxiety and hostility, are possible. At higher doses, drowsiness and loss of motor control occur.

Risks: There's a risk of overdose, with suppressed breathing or heart failure leading to death, usually when combined with other drugs, especially alcohol. Vertigo, lightheadedness, decreased memory and learning ability, and serious loss of coordination are possible. These side effects can last for a long time.

Do not combine with: Alcohol (which will dangerously impair coordination) or anything else that makes you sleepy (i.e., opiates, anesthetics, and other sedatives)-these combinations can lead to death from suppression of breathing and heart rate.

Addiction rating: Unknown.
