I'm an old reformed ex-nonsmoker. I think I got that right. I smoked for several years, gave up, fell back in, nearly drove myself insane giving up again and finally have a zero tolerance approach for myself.
I smoke. Unfortunately a lot. And i don't want to be evangelized, i know myself that it's wrong and that i should quit.
From january on i've a 6 months sabbatical and i'm planning to travel. Maybe a long distance flight is a good start to quit with the help of nicotine patches.
Its a great drug, and smoking is a very effective drug delivery system. When I was a young engineer, working in a big room with 100 other engineers, at least half the folks smoked. Gave them something to do while waiting for the ink to dry on the drawings.....
These days, at least in the US, its socially unacceptable to smoke, but the buzz is impressive for something completely legal.
We don't make it illegal, close the factories, etc. because the US has tried prohibition of addictive drugs before, and it failed. Actually, we've tried prohibition of illegal drugs too and it has failed as well. There is a non-zero chance that in just a few weeks, California will end this stupid war on drugs, at least for some.
