I've been a long time smoker for over 15 years. I'm not proud about it, but I started smoking when I was 12 years old and still in primary school. I didn't see a problem in it, but I started to notice several health problems after a decade and it was too late: I was heavily addicted and I couldn't just stop smoking. I started vaping about a year ago and never looked back. My cardio has improved drastically and I'm a new and better person.
