Replying to Drug test

i know there's many other threads on this, but it seems every one is situation specific so i thought i'd make my own....


Just found out I might be getting drug tested for a job in the next week or two, I smoke pretty regularly, my most accurate guesstimate would be about a gram a week, last time i smoked was last night, I'm in good shape (probably 5%-10% body fat), I always drink a lot of water, i take a fat burner (oxylite), diet is very very low fat, my question is should i go buy a cleanser or will i be alright if i lift hard this week and stick to an almost 0 fat diet?  please and thank you
