How long does tobacco stay in the blood stream is a question that often comes to mind when thinking about the effects of smoking. The answer, unfortunately, is not a simple one. Nicotine, the addictive substance in tobacco, can be detected in the blood for up to several days after the last cigarette is smoked.
However, the amount of time that nicotine stays in the blood depends on a number of factors, including:
* How much you smoke
* How often you smoke
* Your metabolism
* Your age
* Your weight
