Mistakes

On july 2 and july 3 I made a fairly dumb thing and smoked cannabis while with some friends. I now am faced with a drug screening within a week. These two times were the first time I smoked and I must admit, it wasn't very much. As for me, I am 20 years old and weigh about 155 lbs, standing 5'11". I am just curious if the cannaboids would still be detectable in my urine.
