Vaping helped me tremendously. I've been smoke-free for eight months now thanks to e-cigarette devices, and I'm still going strong. Working at a vape shop, I've also heard a lot of success stories from, surprisingly, my older customers. These are people who have been smoking for 20-30 years, some of whom have emphysema and COPD. Thanks to vaping, many of them haven't touched a cigarette in months, and it's dramatically improved their well-being.
Might not work for everyone, but it's a tool that is definitely worth a try.
