Dude, I understand your skepticism and this is normal, but I can guarantee that electronic cigarettes are the safest hobby on the planet for your health. I have been smoking vape for about 4 months and many have told me that I will have lung problems. To avoid this, I even bought the most delicious and premium vape liquid on the market from the vape shop. Recently I decided to undergo an examination and it turned out that I am completely healthy and now I am sure that it is completely safe. So if you smoke, then you can use vape to quit smoking or use vape just as a hobby.
