I'm 23 years old and I have a sister that is very soon turning 17. She lives with my parents and I live abroad for a couple of years now.
My mother noticed that my sister started smoking around 1 year ago and has been asking for my advice on how to convince my sister to quit smoking. We both had separate conversations with her on the topic and explained all the downsides of smoking. Didn't seem to work much.
The problem is that my sister smoking reached a peak point recently, when my sister went to a high school trip over the weekend with some of her classmates. The head teacher that was with them caught her smoking and forced my sister to call my mother and tell her that she has been caught smoking, while the teacher was next to her. So my mother called me and asked what could she do about it (she seemed very worried and out of ideas) when my sister gets back home. I suggested that she should try a different approach and ask my sister about how to deal with the situation. The idea was to see if she recognises that it's not the best thing that she can do.
What other concrete actions can I or my mother take towards convincing my sister to stop smoking? As I understand, my mother believes that my sister will listen more to me than to her (she's in that rebellious teenager period), so that's why she's asking for my help. Also, she believes the fact that I've just been a teenager should help.
A couple of points:
- My mother didn't have to deal with this problem while raising me, since I never found smoking interesting and didn't even try it once.
- My sister's high school is the same I went to. Roughly 70% of the teenagers smoke, unfortunately. It's being perceived as a cool thing to do. There's a lot of smoking in the school breaks.
- In the country where she lives smoking is allowed in bars, pubs, restaurants, clubs. So she is exposed to people smoking and has easy access to cigarettes. Even though selling cigarettes to younger than 18 years olds is illegal, nobody respects that.
- My father is not home very much and we try to keep him out of this, since we believe he won't approach this in an adequate way.
- I have read this question and this question and this article. If you have any other suggestions, please let me know.
