Dangerous when taken on its own, and fatally dangerous when combined with alcohol, Rohypnol is horrifyingly infamous for being the “date-rape drug.”
Rohypnol slows down the central nervous system, causing a range of effects, including exhaustion, sedation, confusion, impaired coordination, impaired judgment and memory loss. Use it, and you can become physically and psychologically incapacitated, meaning you’re unable to move or think—or you’re knocked out. This is why it has been used in targeting people for sexual assault. In the past, it was easy to slip the drug into a drink, because it was colorless and tasteless. In 1997, the drug was reformulated so that when dissolved in light-colored drinks, it will dye the liquid blue. Still, be forewarned: generic versions of Rohypnol may not contain this blue dye.
Rohypnol is lethal when combined with alcohol or other drugs. It can slow the pulse and breathing, leading to unconsciousness, slowed heart rate, suppressed breathing and, ultimately, death.
