I think video games and TV are much bigger health problems than drugs. They're addictive, habit forming, and mentally decaying. Much more than the majority of drugs out there in my opinion.
It's just more socially acceptable to hold a controller or a remote than a pipe.
If there was a War on Video Games (and it actually worked), people would think more instead of just shooting up a bunch of virtual Nazis and feeling like they contributed to society at the end of the day.
At least if you had smoked some weed instead of playing WOW all day, you'd be a little more open-minded.
