aaaaarrrrghhhh, I just can't stand, when someone says, how awful it is to kiss smoker - right after smoking? maybe, but it goes away again... you will get yellow teeth from food as well, coffee etc. BUT you would have to smoke like 3 packs a day to get your teeth that much more yellow, same issue with skin etc. My point is that all these things like WRINKLES, YELLOW TEETH etc etc would appear if u smoked 5 packs a day...you know, it doesn't mean, that if u smoke 3 cigs a day you will get this and that, come on soooo many other chemical sh*t in the air that we all have to breathe evert day!!! And all these models - MOST of them smoke SOMETIMES. They just have 1 cig in a while, smoke on parties... I know sooooooo many, that smoke only while travelling and working and never while they are at home (obviously not addicted). So when u see pic of model, holding a cig, it doesn't mean she does 2 packs a day...
Smoking kills you very slowly??? WHAT DOESN'T...look what we all eat, what chemicals we eat every day, what we have to stress about, we do so many unhealthy things. Of course, if u smoke all the time, it might affect your health, but thats the same thing with food for example - If you will eat McDonald every day, wont that affect your health?? All kinds of cancers are out there, never know who is going to be next victim...non smokers get lung cancer of course, coz they breathe some other thing...maybe too many cars around, who knows.
Just let people do whatever they do... and if they don't do it TOO MUCH, they'll be ok. you have same chances to get lung cancer as NOT-OVERDOING IT smoker or person, who doesn't smoke but walks, sits etc. around people that do...
Many things are bad for you, but some are worse than others. Also, many harmful things are just unavoidable (like breathing in semi-polluted air if you live in a big city), or you would have to become a joyless, cellibate, vegan hermit to avoid them. I'm not straight edge by any means. I'm all for enjoying things in moderation, but I don't understand the sense in putting something so harmful into your body that gives you no pleasure other than a vague sense of satisfaction once you've become addicted to it. Even having three cigs a day over a long course of time greatly increases your risk of cancer. Like many stupid kids I smoked for about a year, but I finally got some sense into me and quit. Even when I smoked, I would have never defended it.
