Pre-employment drug screening?

Sorry, i'm sure everyone asks this, but I need to know if I will pass my drug test. So probably the last 3 weeks of April i smoked about once a day, except 4/20 when i smoked about 3 times. Anyways, May 4 was the last day i smoked for a couple weeks. One day i smoked a bit with a homie, not enough to be really high, but i was buzzing pretty good. Anyways I've been clean since then, and on 6/20 i had to take a pre-employment drug test. I'm 6'1" and about 180-185 lbs, workout 3 days a week for about 1 1/2-2 hrs each and am pretty healthy. i do eat junk food occasionally, but i have a fast metabolism and don't have very much body fat. You think i passed? and also, if i did happen to fail, when they call will they say that i failed the test or just say that i didn't get the job? just kinda worried in case the jefe or jefa answer the phone instead of me. Thanks!
