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.

Depends on drug: Alcohol will disappear in a matter of hours, thc, cannabis, may be detectable for days. Urine tests last longer than blood tests and are usually used for drug screening and thc may remain positive for weeks.
