Not necessarily. You're being very judgmental and also quite narrow-minded.
Not really - I know a lot of stoners who are proper junkies.
I'm not saying that smoking anything that comes along is a good idea, but smoking ridiculously strong weed all the time is fucking retarded. It's good to smoke stuff that isn't so strong sometimes, as long as it has a good flavour and effect.
Holy fuck!!! That's ridiculous. I'm so glad I live in California.
