Which of your tobacco-using friends actions would influence you against tobacco?

If a friend who uses tobacco frequently shared their negative health experiences, such as struggling with respiratory issues or facing a serious illness, it would strongly influence my perspective against tobacco. Additionally, witnessing their withdrawal symptoms or the financial burden of maintaining their habit might further deter me. Their open discussions about regrets and the desire to quit could also reinforce my decision to avoid tobacco. Overall, personal experiences and the consequences they face would significantly impact my views.
