I have noticed that when folks review pipe tobacco's they often mention the nicotine content of the blend. My question is, how can you tell? Do higher levels of nicotine in pipe tobacco affect the brain or the body in some way? I know I have smoked some blends with high nicotine content before but I can never seem to detect anything in a blend that would indicate whether the nicotine content is high, medium, or low. I would like to be able to do this if possible but I'm not sure what to look for in a blend when I'm smoking it. I am a daily smoker of cigarettes as well as pipes. Could that be why I have trouble detecting nicotine in pipe tobaccos?
