GHB & Rohypnol
Rohypnol is a tranquilizer similar to Valium but approximately 10 times more potent. It is an addictive drug and can be abused either for its intoxicating, sedative, euphoria-producing properties, or for its release of growth hormones, which can build muscles. It has been identified as a "date rape" drug used to anaesthetize victims. Street names for Rohypnol include roofies, roopies, rope, ropies, R2, or roaches.
GHB also has a reputation as a "date rape" drug. It is a particularly dangerous drug because it depresses breathing and is easily overdosed. Street names for GHB include G, Liquid Ecstasy, somatomax, scoop, Georgia Home Boy, and Grievous Bodily Harm.
In lower doses, GHB causes drowsiness, dizziness, nausea, and visual disturbances. At higher dosages, unconsciousness, seizures, severe respiratory depression, and coma can occur. Overdoses usually require emergency room treatment, including intensive care for respiratory depression and coma.
