Drug testing welfare recipients: Discuss

[Zazzy]

I'm okay with initial (at the time of hiring) drug testing and random drug testing for people who work in manufacturing positions or positions where you work with heavy machinery because there are serious consequences if someone shows up to work drunk or high and jumps behind the wheel of a dump truck or is the guy in charge of the ladle full of molten steel dangling over your head, or is operating a crane or whatever.

What about for medical professionals, or people who take care of children, or any other job that comes with heavy responsibility for other people's well-being?
