Is it possible to get addicted to marijuana like you could with cigarettes?

I was wondering if it is possible to get seriously addicted to marijuana as you can with cigarettes. I'm pretty sure the only kind of "addiction" you can get, is to the high that you get, but you can't get a physical addiction. Is that true?
