Don't be surprised if a similar move is made here in the U.S... if it hasn't happened already.  I haven't watched Tom and Jerry in quite a while, but it used to be one of my favorites:

They chase each other at high speed wielding axes and hammers. But the famous cartoon duo of Tom and Jerry are in trouble in Britain for smoking on screen.

A channel airing the cartoons has agreed to cut scenes which glamorize smoking after British media regulator Ofcom received a complaint from a viewer who took offense at two episodes.

In the first, "Texas Tom," the hapless cat Tom tries to impress a feline female by rolling a cigarette, lighting it and smoking it with one hand. In the second, "Tennis Chumps," Tom's opponent in a match smokes a large cigar.

My favorite part was what they decided to replace the cigar with:

The Belgian cartoonist Maurice de Bevere replaced his famous creation Lucky Luke's ubiquitous cigarette with a blade of grass, winning him official recognition from the World Health Organization in 1988.

So smoking a cigar is bad, but smoking grass is good?  Well OK, he might not be smoking it, but the undertones are pretty obvious to the adults, even if not to the kids.  Though maybe not... with what they teach in school these days, there may be a lot of kids who pick up on it.
