Drugs come in all different shapes, sizes, colors, and textures. Did you know that crack cocaine isn't the only kind of drug that resembles a rock? Take some time to get tips on identifying these drugs and understanding how they can be consumed.  Use this visual glossary to get smart about the kinds of drugs available in rock form.
