Cocaine isn't the only drug that comes in a powder form. Many drugs, like heroin and PCP, can also be found in powder form. Use this visual glossary to get smart about the kinds of drugs available in powder form.
It can be difficult to distinguish among powders. To know what a particular powder may be might require a trip to a lab or a call to your Poison Control Center: 1-800-222-1222, 24 hours a day, 7 days a week.
Remember, if you find something that looks suspicious, don't handle the substance or sniff it because it could be toxic.
