Will I pass my drug test

I'm not really a smoker I'll take a few puffs every so often like once a month or every other month. The last time I just really smoked was November 21st then took one puff out of a pen cartridge 2 weeks ago. I'm 5'2 113 pounds, I have pretty high metabolism and all I really do is drink water mainly. I have a urine drug test Monday for a job offer am I okay or should I get fake piss. They just offer me a job Wednesday and told me I need to take the drug test by Monday.

Update: I passed it so yay
