I'm currently applying for a school that I know drug tests. Thus I haven't smoked at all since 3/24/2017. Despite my abstinence I'm still testing positive. I have been testing myself every two weeks with test cups from work. Yes I'm a heavier guy at 320, 6' but it's been almost 4 months and I'm still testing positive. Not sure what to do other than drastically start increasing my water intake. The other problem is I don't know when I'll be taking the drug test. It definitely won't be until at least August but still this is kinda weirding me out. I was exercising for a while and have dropped some weight, but I've since stopped for the past two weeks to see if that makes any difference with no change. Anyone got any tips?
