I agree with the first review. This product was recommended to me by the store proprietor. He said "this is the product people use to keep them out of jail when on probation". I used it and failed a pre employment drug screening, also testing positive for THC. I wouldn't depend on this one if you are trying to cover up marijuana use. I have been waiting 9 weeks for a response to my refund request, I also followed those directions, no response, no refund.Product and customer service get an "F"

I had to go to the head shop to get some additional Emergency Detox to cleanse me for a drug screening. And this is after I followed the directions, drank lots of water, sweated big-time, urinated a few times and tested for THC using a standard test strip. I am a bit overweight, granted, but not a frequent or heavy user. Products that proved unsatisfactory (for me) were the QCarboPlus and QCleanChewable.
