Flunitrazepam

Flunitrazepam is sold under the trade name Rohypnol, from which the street name "Rophy" is derived. Other street names include "circles," "Mexican valium," "roofies," and "R-2." Flunitrazepam is a depressant used in the treatment of short-term insomnia and as a hypnotic sedative and pre-anesthetic medication.
Flunitrazepam is manufactured worldwide, particularly in Europe and Latin America, where it is sold legally by prescription. This drug is neither manufactured nor approved for medical use in the United States. Distributors in Texas allegedly travel to Mexico to obtain the drug. In addition, Colombian sources of supply smuggle flunitrazepam into South Florida via international mail services and/or couriers using commercial airlines.
According to law enforcement officials in south Florida, flunitrazepam is routinely referred to as a "club drug," since it is popular in local nightclubs. It is also referred to as the "date rape drug," characteristically causing the victim to experience short-term memory loss after ingestion. It is ingested orally, frequently in conjunction with alcohol or other drugs. High school and college students are the most frequent users of flunitrazepam, commonly using it as an "alcohol extender." Young people also have the misconception that flunitrazepam is unadulterated, and, therefore, "safe" because of pre-sealed bubble packaging.
