I had my doubts about being THC free after 10 days but here two days after taking the ToxinRid 10 day program. I experimented negative! I have smoked daily for many many many years. I needed to pass a urine experimentation for work which I had ample notice. I came across this product from doing web searches and after reading many reviews I figured I would spend the money. Do this program the way it is laid out and it works as advertized. I am a very happy customer for life.
