Not sure: Good question. Single use of marijuana should be out of your urine in 1 to 7 days. Regular use of marijuana – should be out of urine in 7 to 100 days. Single use marijuana can be detected 12 to 24 hours in blood. Regular use marijuana can be detected for 2 to 7 days in blood.Marijuana regular use detected in hair for months. Single use might not be picked up in hair. Bottom line - i don't know.

Results may vary: Consider yourself lucky I guess. The drug tests aren't as accurate as they could be, but I wouldn't keep pushing my luck. It only takes one positive test to really interfere with your life.
