drug driving saliva tests may not be accurate, page-10

...As you said Shiney...

...''No there is no reasonable (fair test for drug impairment) limit with saliva test, so in effect drug testing of drivers will be defacto drug enforcement.''

...There would have to be some limit as a driver could be indirectly be exposed to illegal drugs through say breathing in secondhand smoke...

...The civil liberty groups will not wear that !!!!!!!!!!!!
