I hope you didn't get me wrong, Otis. :s
If you're referring to my mom, she's not saying it's right or if it's natural. She's just saying why. She only smokes when she's stressed. She doesn't smoke for the hell of it, she's an intelligent individual who understands herself very well even if she does smoke. And trust me, she regrets making the decision many years ago to "look cool" in front of her friends, before anything was known about cigarettes.
