Yes, I understood what he was saying and i agree, but the fact is, no matter what the states law is, real time testing won't work with pot. It is either in your system, or it's not. If it is they will say your high and it don't matter if you burnt two weeks ago or two minutes ago, that is why i referanced it with the alcohol. I agree Feds shouldn't stick their noses in State affairs and the good lord knows that Montanans (sp) are a very independent breed who WILL stand up all too well for what they feel their rights are and can be pretty damned stubborn about it!, There should be more states with the backbone you all have. I wasn't trying to dispute the Feds over the states point, but merely stating the "loophole" that would be used to discredit real time testing. Peace:) you can put your gun down now, i'm leaving.
