Ok I've read just about everything in this part of the forum and it has been useless IMO because there are so many ways people say to pass a test and then others come and say it didn't work, don't know what to do, come up with other questions and generally just leave me completely stumped, confused, and worried. The tutorials are not detailed enough and the variables (height, weight, smoking schedule, time sober, etc, etc) are all over the place! I'd like to know what I can buy at GNC that will clean out my system completely (not some drink this hours before the test and cross your fucking fingers trash). I just took a home thc test a few hours ago and tested positive because I just smoked last night, just making sure they work, I have 3. I'm going to buy the cleansing product from GNC and test again afterwards and then again before the real test.
