Could all those drug abusers, asking for methods "to clear their system" to pass drug tests, move to another seperate forum?

Those questions are stupid and annoying. There is only ONE safe method to come out negative in a drug test: not to take any drugs. All others must be noted that all those cheats, walk throughs or come arounds are known to the test developers too. And they have more resources than you to cheat the cheat. In short: there is not ONE certain method to cheat a drug test. So stop asking. And stop drugging.
