Well I smoke pot and I get drug tested about once a month but I have used things to clean my system or dilute my system of THC. Well I went to a local head shop a while back and was going to purchase some of the detox pills but didn't have enough money. One of the workers there was like "You can goto food 4 less and get some certo, that will work too." So I didn't purchase it but the best way to find information is on the internet. So i went to this one place and it says they have heard certo/certa works but it has only been tested by a third party so they don't know for sure. Well I heard from some people around town it works, and what it does is it's a fruit pectin and dilutes your piss a lot but there is other stuff you need to do to clean your dilute your piss too. K well I bought it for like 5 bucks and drug tested and no one has said anything to me so it I think it works. Also, out of no where my friend told me that it works saying that he had to work for wal mart and used it. But i was using it before he told me. Well I have drug tested a couple of times no one has said anything to me but I guess I'm just nervous. Do any of you guys know if this Certo/Certa stuff works? Any information would be of great help. K thanks.
