I would like to know the answer to this question as well. I have a drug test for employment I have to take tomorrow (Tues) and I smoked about a gram and a half over the weekend. I'm going to dilute with water and salt (taste doesnt really bother me, I'll deal with it to pass) and I'm gonna be taking the asprin as well as multivitamin pills. Hopefully this works, God knows I'm crossing my fingers. I've read a lot of success stories, and I'll post mine (hopefully) when I get the results.
