She still using!

I bump into my friend from high school. She still looks the same but alot thinner. I knew in high school someone  told her if you smoke up you ended up losing weight. So she try it and she lost weight. She stunk like she just smoke up before I bump into her. I ask her she still smoking she said yes cause she can't stop. She also told me she afraid if she stop she gain the weight back. Smh stupid for still doing it. People need to grow up!
