Yes, you are right it is a dangerous addiction. My mother died of COPD caused by her many years of smoking. She quite after she found out she had it but it was too late. Though it may have lengthened her life some.

I quit smoking using the patch. I found it easier by finding something to keep my hands busy. I played my GameBoy relentlessly. I did needlework but know it was the GameBoy that saved me. You can't stop in the middle of playing Mario for a cigarette.

Good luck. If you ever need help getting through just PM me.
