A habit, no. Routine, yes. I'm not addicted to marijuana one bit, and could stop if I needed to. I can compare it to the feeling I get when I want/need a cigarette, and it is nothing like it. I don't anticipate smoking like I do smoking a cigarette, which is a problem. Marijuana isn't a threat to my health in any way, so I'm going to toke on, and will soon discard cigarettes and start a cannabis only lifestyle, I've done it before and I have a much cleaner feeling in my mind when I don't fiend for a cigarette, and only desire to smoke marijuana.
