Weird question....

So I got a new job. And a little bit of background on me I’m not a weed smoker and an occasional drinker (26 years old so I’m legal) I never smoke weed ever just don’t care but I did back in December the 9th I believe when I was at a concert with some friends. I didn’t even get high. I’m a little panicked because I need to take a drug test and as a non weed smoker I don’t want it to be somehow still in my system.... will it be?
