Nicotine overdose?

i'm 17 years old and i have been smoking about half a pack of cigarrettes a day for about 6 months now. yesterday i had an incident and i sat and smoked an entire pack of cigarrettes from start to finish (and had probably about a full pack spread out throughout the day...maybe less). is there such a thing as a nicotine overdose? and if so, what are the symptoms? also, does anyone know how much nicotine it takes to consume for you to suffer of an overdose?

There is no such thing as a "nicotine overdose." The effects you may experience, such as dizziness and nausea, are only caused because your body isn't used to the drug in that quantity. But after a little bit, the effects wear off, and you'll be fine.

bcoz u r young only 17 u can still smoke alot but once u r old,ur body resistance is poor then all sorts of disease w'd come to u,the most significant is cancer.lung cancer,throat cancer,nose cancer etc.it's too late by the time u feel regret.stop it now n away from the cigarette-the monster.

You can't really O.D. from smoking cigarettes. You can however make yourself really sick from smoking too many. When you feel nauseated and sick at your stomach, then you know that you've smoke way too much. It is hard to say how much nicotine it takes for you to make yourself sick because everyone is different. I smoke a pack a day but there have been times that I was out drinking and ended up smoking over 2 packs. 2 packs makes me sick but my uncle smokes 5 packs a day and he is fine.
