Do I have the right stuff?

So recently I had to move into the middle of neo-conservative mormon land, and all of the jobs i'm interested in require drug tests. That wasn't going to be a problem at first, because I didn't think I'd get an interview for another week and I had my last weed on the 2nd.

However, I got a ton of interviews yesterday (good thing), and have been offered jobs at a few of them (good thing), but the want me to take a drug test on monday (bad thing)

The weed i had was something between 1/4 and 1/2 of mid-grade stuff, but it had been vaporized before - and I ate it instead of smoking it.

So I read that Cranberry juice and Niacin (Vitamin b3) can help you pass a drug test so I bought a thing of Triple Strength Cranberry fruit concentrate and a bottle of 500mg Niacin pills from the local pharmacy.

Will that be enough? What else can I do to increase my chances of passing?

The masking agent, "Urine Luck" gives 100% results for under $10. You can blaze up until test time if you wish and pass no problemo.
