that is what i was thinking of doing. maybe having some b2 and aspirin on hand and diluting beforehand and then using mid-stream to mix with QF. still worried tho b/c I am a daily smoker and the testing facility is only 1/2 mile away. I would not have a lot of time beforehand to dilute. I may just have to cut back on the smoking until I figure out more about the random policy. There are dot and non-dot jobs and the policy kind of sounds like only dot employees will be randomed, but it doesn't completely clarify. thanks again for the advice:rastasmoke:
