An addiction to anything is a disease, if it is in your family and then you happen to try something in life, you are more prone to bow to it. It has run in my family for years and I'm a smoker with "hope clouds" every 2 or 3 weeks. I've tried a lot but unless you've experienced it, it's tough to describe.
