Well, I'm sorry if this thread is moving towards a theological debate about sins and hypocrisy, etc.
I wrote earlier (post #4) that it might help to discourage youth from taking up smoking if respected leaders made statements. I didn't mean to involve religion. We all come up short and struggle with the discipline that we choose to follow.
It would be interesting to look through the Indonesian school curriculum framework to see what is taught about this issue. I don't have access to any local textbooks, but I'll make the effort to find something online.
