Can one lortab be detected in urine drug screen after not being used for 7 days?

No, most pills in the opiate and benzo families are flushed out in urine within 3-4 days. to be on the safe side, drink cranberry juice (not cocktail) and take daily doses of aspirin (these are natural diuretics and will help you to pee more.) if you are still concerned, try taking Niacin (also known as B3, which can cause a painful sensation on the skin for about 30 minutes but then helps to widen blood vessels and thus, dilute and excrete any toxins in your body.
