Passing a drug screen for marijuana is something that's hard to predict. It really depends on how heavy and long you smoked. It also depends on your weight, BMI and the amount you smoked on your last use.
If it's a urine test and you are not a heavy smoker and have a normal BMI then it will take about 7 - 13 days to get out of your system. If it was a one time use then it will be out in less than 7. If you have been a regular smoker it can stay there for 90 days.
If it's a hair sample, then you will fail.
I'm not sure when they test on board. For my division, in the late '90s and early 2000's, I required drug screens for all new hires and screening if there was suspected usage.
Take care and definitely don't smoke during your contract.
