I escaped the habit 28 years ago. The biggest "immediate" change in my life was that I had to quit going to bars because the smopke made me physically ill - s vefy strong allergic reaction. There may well have been a psychological element in that as well. I have never had a desire for another cigaret, especially, or to use any other tobacco product. However, to this day, I love the side-smoke from somebody else's good cigar, or a good pipe. I'd much rather spend the money on a few more pints.
