No. You use a crack pipe to smoke rock cocaine. A spoon is used for substances you inject. Heroin comes directly to the minds of most people, but the spoon is very versatile. You can inject and use a spoon for cocaine, but not for his brother crack. Actually a spoon is used for many that cook cocaine into it's crack form.

Cocaine and heroin are two totally different chemicals, and require totally different tests be applied.
