Rickochet for the last 20 some years, that has been my one bad habit. I smoked, both cigarettes and weed. Started cigarettes when I was about 17, kept those until about 37. Weed I started about 25, stopped for about 10 years, and just recently picked it up again after a friend gave me a bunch.
I don't smoke every day, heck I only take a small puff when my golf game goes sideways and I'm over it... otherwise I'm sober. We ever get the chance to play 18, I'll do my best to remember that and leave it in the bag.
