Quitting's fucking easy, give me a break.
Whiners can do one 'ooo it's so hard to quit blah blah' nah, just have some willpower.
Anyway smoking's fucked up for sure, however, it's not as simple as that. In England especially smoking a very social thing, it grants you social opportunities that otherwise you would not have access to. In a club, for instance, it's too loud to speak to people inside, so to go outside and have a cigarette is a nice way to actually talk to people.
Also, in group activities - say you're doing some work training or something with 30 other people - if a few of you go outside and smoke, it allows you to get to know those certain people better.
There are a bunch of instances when smoking facilitates conversation - it can be as simple as just asking someone if they have a lighter as an excuse to chat to them.
I've cut down so that I only smoke when I drink now. And that isn't necessarily to do with the social side - I just like the way it feels, I enjoy smoking.
But it's easy as shit to stop if you have the willpower. I smoked when I was 17, and then one day I decided not to anymore. I didn't take a single toke of anything until I was 20 when I decided that I'd pick it up but not in a regular way. It just takes willpower.
