rockbuds Reviewed by rockbuds on . QF 5.7?! I just used 4.2, am I still ok? Hey everyone, I just had a drug test for a job (taken at Labcorp) today, and I bought some Quick Fix at my local smoke shop yesterday for it. I never used QF before and I could have sworn that 4.2 was the latest version, but I guess I was wrong. I checked the directions label and my batch ended in 08, which I guess clears the ones that were recalled (The ones ending in 07). But now I'm still getting all paranoid. What's the difference between 5.7 an 4.2?! Are they gonna be able to detect that Rating: 5
