No and yes: Clinically...No but if you're having urine testing done at work, very possibly. Marijuana can be detected in the urine for at least 6 weeks after use. What may get you off the hook is that you had such a tiny amount (?).

NO: It is not in your system. It was a small amount and is no longer detectable in your bodily samples at this time.
