Depressants will put you to sleep, relieve anxiety and muscle spasms, and prevent seizures.


Barbiturates are older drugs and include butalbital (Fiorina), phenobarbital, Pentothal, Seconal, and Nembutal. A person can rapidly develop dependence on and tolerance to barbiturates, meaning a person needs more and more of them to feel and function normally. This makes them unsafe, increasing the likelihood of coma or death.


Benzodiazepines were developed to replace barbiturates, though they still share many of the undesirable side effects including tolerance and dependence. Some examples are Valium, Xanax, Halcion, Ativan, Klonopin, and Restoril. Rohypnol is a benzodiazepine that is not manufactured or legally marketed in the United States, but it is used illegally.


Lunesta, Ambien, and Sonata are sedative-hypnotic medications approved for the short-term treatment of insomnia that share many of the properties of benzodiazepines. Other CNS depressants include meprobamate, methaqualone (Quaalude), and the illicit drug GHB.



Generally, legitimate pharmaceutical products are diverted to the illicit market. Teens can obtain depressants from the family medicine cabinet, friends, family members, the Internet, doctors, and hospitals.
