Some date rape drugs look like regular drinks or other drugs you may be used to seeing. Drugs such as Rohypnol, GHB, GBL, and ketamine may look like pills, liquid, or powders. Often date rape drugs have no color, no smell, and no taste when added to a drink or food.

If someone adds a date rape drug to a drink, it may change the color of a clear drink or make your drink look cloudy. But changes can be hard to see if the drink is dark (such as cola or beer) or if the room is dark. You can’t always tell if a drug has been added to your drink just by looking at it or tasting it.
