Hey city I just had a quick question I was hoping some one could clear up for me. I may have to take a drug test for the mip program I am currently on, the test will possibly be on june 15. I quit smoking today the 5th, I plan on working out every day up until and I am of course drinking a lot of water and cranberry juice. I am also planning on drinking some detox teas and just bought a bottle of 500mg niacin from gnc. Now my question is, say I got a 7 day detox kit from gnc, could it be screened even though I wouldn't be taking it for two days? Also does anyone think this may be not needed do to the other stuff I'm doing? Thanks in advance, I look foward to the help.
