Oh Yes! I have COPD and was smoking 50 a day. I couldn't walk to the chemist and back (about 400 meters) without being covered in sweat and stopping everything couple of minutes to get my breath back. Since starting to vape I hardly ever have to use my blue inhaler, I can get around on foot without having to take a backpack with a towel in. And not to be overlooked, vaping is fun! and fun makes you happy! and happiness makes you healthy. So it's win win win!
