What are issues of environmental contamination?

Cocaine, in its smokable form, can deposit on hair.

Most individuals who do not use cocaine will also not be around smoked cocaine. If an individual lives with a cocaine user, he/she could be subject to cocaine exposure in the living environment. The cocaine residue left by the user could result in both a urine and hair drug test positive if accidentally ingested by a non-user.

If external exposure is limited, the cocaine should wash out of hair using normal hygienic methods. If the exposure is more inte
