My Mom Just Started Smoking

My mom has taken good care of all of her kids. She's never been hooked on drugs before. Now all she does is smoke crack with her so called " friend".
I need to know what I can do to help her.
Talk to her and in a nice way, friends are a strong factor that could influence your mom. Tell your mom how is was before she smoke, more importantly that is cause harm in her life. tell her that you've saying this to her because you are concern and you love her. Somehow, ask your mom if she has a problem and your there to help her. She will need all the understanding she can get.
