I wouldn't call that dependent. You can't get addicted to weed. It's been proven many times in various studies.
I'd call numerous times a week dependent. Just talk to him about it if it makes you nervous about his habits. If he's a good guy, he'll listen and talk to you about it.
If he doesn't care, just leave the guy...he's not worth your time.
If he chooses to smoke weed, sit on the couch and not hang out with you or even get out the house, then yeah I would say also you can find better. If it is an on going problem tell him to put his priorities in check, you or the weed.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
