Hello , Thank you for your query at DoctorSpring.
I understand that you are a recovering addict with congestive heart failure and arthritis . Since you have been clean for the past 8 months , the results could be due to false positive cocaine in the urine.
I would like to know some additional information from you :
1. Have you taken Amoxicillin or consumed coffee or tea /tonic water before the test or in the recent past ?
2. Are you keeping cocaine at home ? Even if you not using it, is there any chance you are coming in contact with it ? (Like handling them)
3. Did you take any natural remedies or similar medications in the recent past ?
You can reply as followup consult. T
