I have only been vaping for 74 days now. But my health has improved so much. I was a pack a day smoker for 15 years and tried quiting with the gum, patches, and even cold turkey for years and could never quit. Heres the catch, I am Asthmatic. While smoking a used 1 Inhaler that should last 30 days in 1-2 weeks. I couldnt play with my kids for more than 10-15 mins without a break. And I was always broke buying a pack a day. Since I bought my first Vaporizer 74 days ago. I can play with my kids for hours now. Im saving money, and my Inhaler lasts me just under 30 days. Me changing to vaping has to be the best thing I have ever done for myself EVER. And my kids love the energy I now have. Vaping has literally saved my life.
