Does Wiz Khalifa rap about anything other than weed?

I really like rap and hip hop and I listen to artists like Eminem, Jay-Z, 2Pac, Biggie, etc and I know they sometimes rap about weed but it's not in every single song like with Wiz. I just think Wiz Khalifa gets boring because he raps about weed all the time and he sounds like he's obsessed with it. Does anyone agree?
