How are barbiturates used?

Doctors use short-acting barbiturates as general anaesthetics – a single injection of thiopental can knock you out in 10– 20 seconds. Consciousness returns in 20-30 minutes. Doctors use longer-lasting types, like phenobarbital, to treat epilepsy. All barbiturates are extremely addictive and so cannot be used long term.
