well im not sure on the whole thing but you took the right course of action. So you should be good to go. Otherwise Go look at the top issue in this thread and look for my one and only post, that states what most people I know do on a random and it works 100% of the time if you do it as I stated. Even if you smoked the day prior to the test, if you drink a good amount of water before the actual drug test, and take the instructions in the thread i was talking about, but this isn't me stating that you should smoke up to the day prior, this is mainly stating what to do if its a random drug test and you didn't have a choice.
