Well, breaking the habit, which I tried many times during 50 years smoking the weed (about 25 each day) was a total failure for me. Even watching my 40 a day father
die didn't shock me sufficiently enough to stop smoking.
I then read on the Internet that a gradual switch to pipe smoking was the easiest way by far (no inhaling) and less harmful. I tried a few pleasant tobaccos and found one that suited me.
Whilst returning from some overseas Consultancy work I developed the biggest cold and flu ever. No, not caused by the pipe smoking, but my Clients offices which were freezing. After five days or so I felt a lot better, but then questioned myself, why smoke again? and yes that is what resulted. It was so easy to stop, I could hardly believe it myself.
Here ended a lifetime, about 60 years in total, of smoking. I still keep my pipes and the partly filled pouch of tobacco to remind me what I achieved on that day
Please try it, have a lousy cold and "flu and just stop for ever
