True, Sam. The biggest problem with this whole issue is that we don't have adequate empirical evidence concerning *how* bad second-hand smoke is. And further, how bad second-hand smoke is compared to other air contaminates or, for that matter, any other contaminates that the average person is exposed to. Common sense tells us one thing, but common sense isn't the same as empirical evidence. I have no doubt that second-hand smoke isn't good for one's health. But as far as *how bad,* the issue is contested.
