Over-eating damages parents and thus indirectly children. Even wasting time reading trash like The National Inquirer makes people less productive and less effective as parents. I'd like to see that rag disappear, but not by government dictate. True, drugs contribute to some people ruining their own lives and damaging the lives of loved ones. To conflate drug use with violent crime is to utterly confuse the issue and to open the door to tyranny.
Drug abuse is rampant.
There are nihilistic tendencies in our culture, perpetuated in many of our schools, which are unhealthy for the culture. However, just because something is unhealthy, doesn't mean the government can solve it. So the answer is not to call for more government controls, but to return responsibility to the individual. The epitome of the Republican position is something that Bob Dole said in his last campaign. Well, under us, government will grow less quickly than it would under Bill Clinton.
