How Rohypnol is abused
Across the country, there are reports of people "dosing" other people without their knowledge by dropping whole or crushed Rohypnol tablets into their drinks. When Rohypnol is dissolved in a drink, you usually can't see it, smell it, or taste it. Therefore, if you are "dosed," you probably won't know that you're being drugged. Soft drinks, punch, beer, or other alcoholic beverages can all provide the disguise.
