Firstly I have done my research. I know abt all of the methods and quick fix and all of that. I work in hvac and my job does not randomly drug test HOWEVER they will test if there is an accident in the vehicle or an injury on the field. If I were to be involved in an incident I would have to take the test on the same day. What are some strategies that I could use so that I don't need to worry about this? I was thinking keeping quick fix in my lunchbox or something that way I'd have time to stuff it in my pants before a test, any other ideas?
