I wouldnt say answer A or B is right. Smoking is not a choice of God but of man. You chose to smoke and now you are choosing not to. And I don't want to say you were like "oh well, look at me, I gave up smoking in one day." I definitely believe that it has been something weighing on your mind. Maybe you saw how much it hurt your mother and you are trying to mend things with her, consciously you body just did not want one. And I do believe that all our actions are 50% physical need and 50% mental need. Maybe your mental need is weighing more and telling you that you are doing the right thing. Your mother only wants the best from you, and she knows smoking is the fast way to a short life. As much as you think your mother probably doesn't care about you...she obviously does are she wouldn't have yelled at you for smoking. Its love...trust me. There is a difference between yelling at you because she cares and well, that is pretty much it. You can tell when your mother stops loving you because she will leave you and neglate you. Which I thought was what my mother was doing to me. Over two years ago was the last time I saw my mother. TWO YEARS. Try not talking to your mother for two years. Then you will reconsider the ideas of love and relationship with your mother. I received a letter from my mother the other day in the mail. She told me how much she missed me, how sorry she was that she hasn't attempted to get ahold of me in 2 years. I cried....oh man, did I ever cry. Just please understand that your mother cares for you and that she only wants the best for you. Like you said yourself..."cigarettes just waste my money and make it hard to breathe and will eventually lead to an untimely death,"...so maybe you really should just give up the death trap. Tell your mother the truth that the first time she asked you... you did lie. But, now you are being honest with her (only if you truly did give up smoking). The art of any lifestyle is communication. Communicate with your mother...trust me... it will mean the world to you both.

P.S. Your believe is your own. I cannot stop you from believing in your faith. But, I must say...God works in mysterious ways... Just wait to see =)
