The second point is that checking a drug or a substance allows a person, essentially, to make a lifesaving decision not to consume it should it turn out to be not what it says on the box, so to speak. That's actually incredibly important and nothing to be scoffed at or taken lightly. It doesn't need to happen every day. It doesn't need to happen in every community. For every time that happens and a person is able to negotiate their way out of a potentially risky situation, then that's worthwhile.
