What do barbiturates do to the body?
Barbiturates increase the activity of a chemical in the brain that helps transmit signals. This chemical is known as gamma amino butyric acid (GABA). As a medication, they reduce muscle spasms, relieve anxiety, prevent seizures, and induce sleep.
How do barbiturates affect the nervous system?
Specifically, barbiturates depress the central nervous system by enhancing the activity of gamma-aminobutyric acid (GABA). GABA is an inhibitory neurotransmitter that suppresses any generated nerve impulse, thus creating an overall depression of the central nervous system.
What are barbiturates made from?

Are barbiturates physically addictive?
While the popularity of barbiturate abuse has declined in recent years, these drugs are still abused. Barbiturates have a very high physical and psychological addiction potential – taking barbiturates for as little as one month can cause significant changes in the function and structure of the brain.
Who discovered barbiturates?
How are barbiturates produced?
Barbituric acid, the precursor of barbiturates, was first produced in 1864 by condensation of malonic acid and urea; it had no central nervous system (CNS) effects.
Where did barbiturates come from?
Is barbiturates a controlled substance?
Barbiturates are Schedule II, III, and IV depressants under the Controlled Substances Act.
What are the effects of barbiturates?
