I smoke it pretty much all day everyday and I still move at a mile a minute, I do folks heads in with how I'm always on the go and I can't stand slow or lazy people. Without the weed I'd really be bouncing off the walls
As for addictive I don't think so really, the worst I have to deal with if I stop smoking for a few days (a very rare thing ) is night sweats and really vivid dreams and that's only with a seriously heavy habit. Definitely habit forming though but so is anything we find enjoyable.
