It's a pretty darn hard addiction to break. I've smoked since a very young age, and all the stress in life makes it even harder to quit. Overall, I know quitting smoking is one of the best health choices that one can make so I'm working on it. It's also damn costly, I used to pay $2.73 a pack and now it's $6-$7. It's quite a financial burden, all health issues aside. I thought I'd never be able to quit drinking, but it wasn't as hard as I thought. I quit smoking for 3 months once, never was it easy that entire time, and ultimately something extremely stressful occurred within my family and I bought a pack just to try to find anything to help. Smoking is expensive, bad for your health, bad for your teeth, bad for those around you, and it stinks.
I don't believe in restricting choices that one can make, so I sorta' have a libertarian stance on it
...but I think people need realize that smoking does nothing for you if you're not addicted, so please don't start. Besides guys, check out dating sites and you'll see that most lady's are seeking non-smokers. Plenty of reasons to never start. When I was younger you could still find cigarettes vending machines around and lots of liquor stores didn't check ID. At least in that sense things seem to be much more strict now.
Oh well, people deserve to make their own choices, and that includes bad ones. It's not like people can really smoke in most bars, restaurants or airplanes anymore.
