How much nicotine do you get from smoking a cigarette?

If Malboro Light has .6 mgs of nicotine, how much of that would the average smoker inhale? The cigarette isn't constantly being inhaled.

Does changing to a lower nicotine brand, such as one with .1 mgs of nicotine help to ween a person off nicotine?

It is a proven fact that every smoker inhales a different amount of nicotine, depending on the way that individual inhales. "Lights" aren't really always lighter because they have "lowered tar and nicotine." You could smoke a full flavored cigarette differently and it would have less, depending on the person's smoking habits. (Some people breath in deeper or hold the smoke in longer.) Don't smoke; it'll drag you down.

too much switch to the patch n stop smoking ..save ur life

Way too much.

Thanks for asking!

I used to smoke Marlboro reds 100, also known as death. Did for about an year which does not seem long but I would go through a pack easily a day. Sometimes do 3 in a row. Well let me tell you nicotine had no meaning, sometimes if I run out I would take some paper and smoke just that, and feel a little better. One day I just said to myself that life sucks whether you smoke or not, and thought to myself that if I keep smoking I will fail in life and not get jobs etc. It just happened in one moment I put out the cigarette and said it would be my last, and I have been clean for a month now. You REALLY need to get a cigarette filter, they are like $5 and they filter out the nicotine but leave most of the flavor. Its a bit hard to get used to it but they are awesome, plus they look nice too.
Good luck
