I are heroin. Flunitrazepam is a tranquilizer developed in the 1960s and early 1970s by Hoffman-La Roche, Inc., and first marketed under the trade name Rohypnol in Switzerland in 1975. This class of drugs is used to treat anxiety, convulsions, muscle tension and sleep disorders. Its powerful sedative effects can last up to 12 hours, with some residual effects occurring as late as 24 hours later. Low doses of Rohypnol may cause drowsiness, dizziness, motor incoordination, memory loss, gastrointestinal upsets, headache, reduced blood pressure, visual disturbances, dry mouth, and hangover.
Higher doses can cause coma, respiratory depression, and even death.
In southern Florida, six deaths occurred in which flunitrazepam use was found during autopsy. Rohypnol impairs mental judgment and reaction time, and individuals who drive under its influence increase their chances of automobile accidents. Law enforcement officers have frequently reported observing severely impaired driving ability in motorists who have used Rohypnol along with small amounts of alcohol. Today, Rohypnol is legally marketed in 64 countries in Europe, South America, Africa, the Middle East and Asia. Although Rohypnol is the most common trade name product containing flunitrazepam, in many countries there are additional generic and trade name products.
