Actually an important article - it talks about setting cut-off TCH levels for DWI (DUI) testing.

2-nanogram limit -used in some States, but results in false positives - if you will

 

5-nanogram limit - the yanks say it's similar to 0.08%blood alcohol (NOT!)

 

Hopefully the 5-nanogram limit will be seen as a standard level here too...

Anyone know the cut off's of the tests used here?
