So are you saying I shouldn't have been allowed to get a drivers license because I drank alcohol a week before my driving test. Pot can show up in a test a month after someone smokes it but they aren't still high.
Be the way, I was 23 when I got my license so it was legal for me to drink.
Sure, muggs. Pot and alcohol are debatable topics - in this scenario as well. But anyone who shows that they are doing hard drugs is showing a blatant disregard for the law (which cannot be condoned on the road), are likely addicted (which means that they will have problems NOT taking the drug in question while driving), are showing enormous irresponsibility with regard to their own well-being (yes, that's their business - but it shows that they are, on average, not so likely to be concerned with others' well-being), shouldn't be driving. In my town, we have several fatal car wrecks every year (often involving, maiming or killing passers-by) involving kids on drugs. I have a family. I do NOT want kids driving around who do drugs. You can disagree with that. But the vast, vast majority of parents will agree with me. Anything that makes my kids and my wife safer from the predations of others is something that I will strongly consider.
