Nicotine causes circulatory problems. I would see a doctor. My step father just had a triple bypass and they blamed nicotine and a sedentary lifestyle. He was a truck owner/operator for 15 years... He is now on a heart waiting list and they drug test him for nicotine. If he keeps smoking they wont even keep him on the list... I'm using vaping to quit nicotine completely. Want to step myself down as much as possible...
