Date rape drugs are powerful and dangerous. They can be slipped into your drink when you are not looking. Rhohypnol has no color, smell, or taste, so you can't tell if you are being drugged/ It's cheap, also, so that is no bar for a potential rapist should he be set on this form of criminality. Rohypnol comes as a pill that dissolves in liquids. Some are small, round, and white. Newer pills are oval and green-gray in color.
When slipped into a drink, a dye in these new pills makes clear liquids turn bright blue and dark drinks turn cloudy. But this color change might be hard to see in a dark drink, like cola or dark beer, or in a dark room. Also, the pills with no dye are still available. The pills may be ground up into a powder.Treat your drink like your purse: don't take your eyes off it and certainly don't leave it on the table while you dance or speak to someone at another table.
