Drug test: No, it isn't some confounder. By your admission, you are a Cocaine user. A hair test checks metabolites from months in the past. That is why the federal government uses it.

Cocaine in hair: No.

Because the test only looks. for a metabolite that only comes from cocaine and not from novacaine.You need to get honest with yourself. Before you die from using it.
