Good for you and I'll always be supportive!
You are correct that tobacco products don't cause cancer; they CAN lead to cancer and often do so. Let me clarify: if tobacco caused cancer, all long-term users would get cancer and we know that not to be true. However, tobacco is NOT good and does not treat your body well! Some say that tobacco is more addictive than opiates; that is a load of crap. It's a habit and habits can be ssubstituted for better habits, but you need a contradictory habit. If you feel like a dip, drink a glass of milk or eat a banana. Tobacco and those flavors will not blend! And that changes the habit to a healthy habit.
Just a tip that I hope helps you.
