1. ROHYPNOL

• Rohypnol is the brand name of flunitrazepam, a surgical anaesthetic or sleeping pill. It is around 10 times more potent than the most common prescription sleeping pills.
• The pills are usually round, white, and labelled "Roche," Sometimes, the pills are ground up into a powder. Rohypnol dissolves quickly in liquid. It has a bitter taste when mixed in a drink, but like GHB, its taste may be mostly covered.
• Prescription versions should turn blue in a drink; counterfeit versions will not
• Rohypnol tablets are called Roofies, Roach, Roofenol, Roché, La Rocha, Roll-and-Fall, Rope, or The Forget-Me Pill (and other names)

2. GHB

• GHB is available as a clear, slightly salty tasting liquid or white powder
• Slang / Street Names: Grievous Bodily Harm, G an others
• GHB is often manufactured in homes with recipes and ingredients found and purchased on the Internet
• GHB is a central nervous system depressant that can relax or sedate the body; intoxicating effects begin 10 to 20 minutes after the drug is taken. The effects typically last up to 4 hours, but overdose can occur quickly
• GHB is cleared from the body relatively quickly, so it is sometimes difficult to detect in emergency rooms and other treatment facilities
