Brief Answer:
Consultation

Detailed Answer:
Hello, and thanks for your question.

False-positives for cocaine are extremely rare. Lab error, or taking the antibiotics amoxicillin or ampicillin, can sometimes cause it. Diabetics such as you rarely can test positive as well. Did you do any other substances, such as marijuana? These are often dipped in cocaine even if you aren't aware, which can cause a positive result.

Detailed Answer:
Supplements are unregulated and could in theory contain traces of stimulants, but highly unlikely to contain cocaine. I doubt this is the source of the problem. More like related to your diabetes.
