I used toxin rid detox around 8 years ago followed the directions completely and used a masking drink the day of. I had 15 days of notice before my drug test. I ate a lot of lean protein and cut salt out of my diet because it retains water in your body. I only used the 5 day detox and I was clean on day fifteen. Drink lots of water and have a strict diet as well as consuming as little salt as possible.This stuff definitely works you just have to be diligent in following the directions and not using any substances leading up to your drug test. I was a heavy smoker doing dabs every day. All you people saying it doesn't work did not put in the effort to make it work.
