In 2007 I was hospitalised for surgery and was given a weeks worth of morphine belly injections. I never wanted another cigarette again! Even when the women across the room would return from having a smoke I got the sickest feeling. Anyway, yrs later, as I was listening to my fave scientist, Dr Carl, unravel listeners mysteries on his weekly radio spot, a woman called in stating she and her husband had tried everything to quit cigs. Then she had morphine post hip replacement surgery and never wanted another smoke, but her husband was still battling. I listened as Dr Carl tried explaining how this "might work in a small number of the population" by way of over-riding the brain's nicotine receptors. Before this I had no idea it was the morphine that turned me off cigs. When I mentioned it to my GP, just for interest sake, he laughed qiuetly and said: "yeah, don't tell anyone." I still get that queasy feeling if I'm sitting in traffic and the driver in front has a cigarette wafting out the window.
