Can you sub? Will it be observed? Personally the dilution method didn,t work for me and I ended up subbing. I've not really heard real good things about the detox and masking drinks, but some people swear they work. Kind of hit and miss it seems. Not a whole lot of time to clean out, though if your test is Thurs. Pot can take any where from 3 days to 3 months to clear naturally! Very unfair for such a harmless drug if you ask me!
