We all know the dangers of smoking and 2nd hand smoke. I for one gets irritated with smoke. I can't help but wonder why some people likes to smoke a lot when all you ever get from that is smoke, nicotine and carcinogens. Plus the smelly clothes you get from it. I think it's unhygienic. It also is a challenge for smoking population to quit their habit of smoking. It entails great self determintation and control to quit from it. But learning about electronic cigarette seems like promising. I think if you want to quit from smoking you have to slowly kick that habit out of your system and using electronic cigarettes will help you with that without harming your health.
