Does smoking nicotine cause slight tachyardia?

I noticed that whenever I smoke my heartbeat increases. I'll have maybe one or two cigarettes and it'll happen. I mostly smoke "strong" brands like Dunhill Red/Black long or Marlboro Red. Is this expected when smoking cigarettes?|||Yes, nicotine is a stimulant and will affect your heart rate, as well as blood pressure, respiration and your general health, but that much you already know. Bottom line is that it is a stimulant and will act as such.|||it is a reaction to the nicotine. If you stop smoking it will take abouot 2 years for your lungs to return to normal.|||Yes, definitely, It is the body's way of trying to "get rid" of the nicotine.
