You could argue that reading is addictive, maybe some people find math so as well. I became addicted to computers when I was a kid and we didn't even have the internet.

Silly, yes, but you can bet that there'd be lawsuits claiming all sorts of things are addictive and some number will find sympathetic juries. Seems like a pretty bad idea to me.
