Age Limit on smoking Legal substances?

No.
Where did you get these "magic facts?
My main point is such: lets say you start drinking and smoking at age 5.
And you want to quit at age 15.
Smoking withdrawal is annoying. (you can get quite cranky and hungry)
Alcohol withdrawal can be fatal. (you will hallucination, have Grand mal seizures, strokes, and heart attacks)

...
So please stop telling me how bas smoking is and how helpful drinking is.

Hell, I'm sick and having surgery thus haven't smoked for a month and I'm starving all day long.

Also I have anxiety attacks and this rampant need of smoking a fucking cigarette...

But I, from the smoker side, think it's perfect to ban smoking indoors and in public places. Whereas I also believe that people that smoke don't deserve the treating they get because a lot of them have issues regarding health, and need medical assistance. As for second hand smoking, you people who have problems with your relatives that smoke you should talk to them and approach them not with a moralist speech but with a comprehensive and understanding one. WE HATE BEING TOLD SMOKING IS BAD FOR OUR HEALTH, qe already know and feel its effects all the time.

Lastly, I must say that age 18 is a reasonable age for choosing what to do, whether it involves smoking and drinking or not. Anyhow, I live in a country where smoking and drinking is socially accepted so I don't have many troubles...
