Does external exposure to certain drugs, like Marijuana or crack smoke, affect the hair drug test results?

To rule out the possibility of external contamination, Hair drug testing (where appropriate) looks for both parent & metabolite (bi-product) of drug usage. For Marijuana analysis, our laboratory detects only the metabolite (THC-COOH). This metabolite is only produced by the body and cannot be an environmental contaminant.
