Will I pass a drug test?

I recieved an incredible job offer last week and was now told I need to take a pre-employment screening. I used to take delta-9 edibles once to twice a week and will be two weeks off when I take the test. I am fairly fit and work out 3-4 times a week. I was negative on two at home tests from Walgreens, but cannot stop worrying about it. How likely am I to pass?
