I used to laugh at this quote when addicted to tobacco. Never ever felt that I was fool at that time.
Now realise after quitting for seven years plus, it was indeed a correct statement - Yes... we were fools at the other end.
I tend to say now : A cigarette is pinch of addiction rolled in your mind with persistence to quit at one end, and help of becomeanex.org on the end..
Have a good day !
