Smoking everyday=/=addiction. Addiction implies that you'd struggle to not smoke it, that you'd have withdrawals, that you're dependent on the substance. I know plenty of people who smoke basically every day who can put it down indefinitely if, for example, their parents are staying with them for a week. Some people just like to smoke, man. It's a great buzz. It doesn't mean you're dependent on it because you smoke. I've had this argument with the social conservative types a lot. They think that because you smoke that you're dependent unless you only smoke a couple of times a month. They're all psychologists when it comes to this particular subject.
I know some people who freak out when they don't have any. There's a very strong argument that that's an addiction, since I can't really think of one good reason why you would flip shit if you're not dependent. Some people want you to think that being an addict simply means that you do something on a regular basis, but the truth is that only you can really know for sure if you're addicted or not. It's a mental state, and other people can't read your mind. If someone's telling you that you're addicted to weed because you smoke it every 3rd day, or even every day, then they're just an asshole who's trying to pass judgment on you. Their egocentrism holds no water.
