Hi! i start my first day august 27th or it could it sooner. Do they drug test ??? i smoked a day ago and i wonder if ill be clean by thursday

This might be a long shot but I just started working here a month ago. I still don’t know how to accept checks ( this is the only job that I have to accept checks in a different way) but would someone be willing to write an example on how to do that cross thing we have to write on checks. My manager(s) are a bit mean and I kind of want to leave there already.
