I have been vaping for 76 days. My mother had a heart attack at 45.. I just turned 40, I know a lot of you have done way more research that I could ever do so what I am asking is Does the nicotine I vape damage my heart? I know some say it raises BP and heart rate but my BP has always been 100/60 or lower.... My resting HR is around 66 bmp. I know your not doctors but would like to know what your thoughts are.
