I stopped smoking after 40 plus years. I smoked 1 1/2 packs a day. Was on high blood pressure pills for last 10 years. I started vaping 8 months ago. And was able to stop my High blood pressure pills 6 months ago. My Doctors is happy I no longer smoke. And off the medication for good. My breathing has gotten better also after a short time not smoking. And he has recommended vaping to others. I love all the different flavors we can choose from too. Unlike cigarette that taste bad and burn your lungs and clothes.
