This risky behavior would raise my risk of getting lung cancer, heart disease, or even a stroke
No. I don't want to harm my body like that. If you want to go get ice cream later, we can, but I am going to leave now.
I'm really glad I decided no say no. I'm still young and have so much of my life ahead of me. Starting the bad habit of smoking already would only increase so many health risks. It would not only affect me physically, but also mentally and emotionally too if I would have ever faced withdrawal.
