When I started smoking I used to smoke other people's cigarettes. Then I started buying my own out of embarrassment. I wasn't a tobacco addict in my own mind at that stage, I just like smoking. It was only when I wanted to quit I found it really hard to stay off for long periods. Eventually I managed it. The level I smoked at was about 10-15 a day. I know a man who smokes 60 a day. He is probably more addicted than I was but it's a matter of degree rather than me being able to look down on him as an addict as compared to my moderate level of smoking.
