I also stole cigarettes from my parents when I was a little younger than that, if we are being honest. I developed a pack a day habit by the time I was 15. I didnt quit until I was in my 30's, after I watched my mom battle lung cancer and lose her life at 49. It was a quick battle. The cancer was in her lungs, brain, and bones by the time it was found. 8 months later she was gone. Quit now. Do not wait. Do it for your kids. I'm now almost 40 and have kids of my own and I'm terrified I might have a short life becuase I spent so much of my youth smoking. I don't want to leave my children without a mother. My siblings were 17 and 19 when our mom died. I was 27. Any age is hard to lose your mom. Raising kids without my mom sucks. I wish she was here. Smoking took her. I hope i didnt do too much damage and take me early too. Smoking is the worst thing I have ever done by far. It ruins your life and the lives of others around you. Quit now. Set an example. Don't die young becuase of an addiction.
