Nobody chooses dope over a job and career unless they can't stop using the stuff. That is unless you want to say they chose dope because they couldn't quit.
And that is the way it should be. The last thing I want to see is a druggie wheeling around in an 80,000 lb 70 foot death machine.
Yes and no. I mean........I certainly don't want to drive around anybody who is intoxicated, especially in an 18 wheeler. However there is a distinct difference between being intoxicated and having residual drugs or alcohol in your system from what you were doing in your off duty hours.
A friend of mine works for ConWay express which was recently sold to another company. He told me that every driver gets pulled for a drug test after vacation. Why? Because vacation is when people let loose a bit, and residual THC can stay in your system from three to four weeks.
So they were not testing to see if you came back loaded, they tested to see what you did while on vacation, and to me, that's an invasion of privacy.
