Will be positive: If you're a regular user, and it sounds like you are, THC will show up in a blood test for up to 3 days. Urine tests may be positive for the marijuanas metabolite THC-COOH for up to 30 days. Consider submitting another question to us: "What are the health effects of long term, regular marijuana use on my health?'" That's something else you need to know.
