Perhaps I am assuming too much of the subtext. People commonly say things like this to suggest that it necessarily causes addiction which makes it a Bad Thing.

Perhaps I am assuming too much of the subtext. People commonly say things like this to suggest that it necessarily causes addiction which makes it a Bad Thing. It is true generally that it "can" cause addiction but only true circumstantially that it "does" cause addiction. Again, I may be reading too much into the comment but it seemed to be trying to make the "necessarily does cause addiction" point.
