Cardiologist 's  Response
Hello,

It is likely that your test will result positive, if you have not taken weed for 4 days. This is because weed remains in your body for up to 30 days and 4 days is a too short period of time.

Take care. Hope I have answered your question. Let me know if I can assist you further.

Regards,
Dr. Ilir Sharka, Cardiologist
