It all depends on who you are & your physiology, right? I was super addicted to nicotine (I can say that nicotine is perhaps 500x more addictive than weed, and about 10,000x more addictive than coffee, and about 50x more addictive than alcohol - all of which I have been addicted to at varying times in my life).

I've known people that were fine smoking a cigarette every 3rd day. I'm not one and that would put me on a path of relapse in a hurry.

I'll agree that avoiding addiction takes discipline, but once addicted, it depends to what, and who you are whether you need to focus on recurring abstinence or if more moderation is the ticket.
