Fluids like powerade or gatorade are more helpful than water because they help keep the S/G (specific gravity) within satisfactory ranges. S/G is tested along with creatinine in order to determine an overly-diluted sample. Drinking a bunch of water causes the S/G and creatinine levels to take a nosedive and thus sending up the "diluted" flags at the lab.[/QUOTE]

Powerade, Gatorade, and Smart Water do not help from my experience this past week. Got a call from my PO that my sample was diluted and I was given a warning that it better not happen again! I don't know how diluting works for anyone because I didn't even drink a huge amount and my sample was rejected. I had to go in the next day to re-take my test....not cool! THC sucks!!!
