Wow, who knew that some truck drivers occasionally smoke Pot?
In some states, like Michigan, recreational use is legal. Unlike alcohol, pot chemicals stay in the bloodstream in detectable quantity, long after the user has sobered up, so a blood test is not determinative of DUI, like it is for alcohol.
And, as thegreatdane noted, the industry has largely broken the unions, and cut pay and benefits so much that driving truck is not attractive anymore.
