Explanation:

Rohypnol, known as “roofies” and roaches,” is a sedative-hypnotic drug. Increasing dosages produces signs of progressive central

nervous system depression ranging from sedation to sleep. Chronic use of high doses leads to the development of tolerance, but a level

of intoxication can always be reached if the dose is high enough. Chronic use of large doses also leads to physical dependence and

withdrawal if usage is abruptly stopped. Withdrawal symptoms can be lessened to a certain extent if a drug from another class of

sedatives is substituted. When drugs from this class are taken together, one sees a far greater central nervous system depressant effect

than otherwise would be expected, especially with alcohol. This is called “synergism.” Overdose will cause mental clouding, loss of

muscular coordination, and eventually respiratory arrest.

The principal minor tranquilizers are the benzodiazepines, among which are diazepam (Valium), chlordiazepoxide (Librium), and alprazolam (Xanax). These drugs have a calming effect and eliminate both the physical and psychological effects of anxiety or fear.
