Drug/alcohol test

So I took an edible on 01/10 late night and I don’t really take those much. Also, the last time I hit a pen was on December 31st. I didn’t realize I would be offered a job this soon that requires me to drug test. I can kinda choose when I wanna be tested so I’m gonna try to push it back as much as possible, but I did wanna start working asap. Also, it means an alcohol test and I had no idea that was a thing either. The last time I drank was December 31st. What do I do?
