I quit a long term 2 pack a day habit using the patch. LONG term, it is certainly safer because of no damage to lungs and fewer toxins. But short term, I think the nicotine itself has an effect on your arteries and blood flow. So, that can't be good, long term. I was not on hormones when I quit and it took me quite a while. Maybe a year on the patch and occasional gum, but I didn't smoke. Watch your diet carefully. I gained a lot of weight as I was a stress smoker, and became a stress eater. I have lost 30 lbs from my heaviest, but still need 15-20 to go. Stopping smoking was the hardest thing that I ever did, here is wishing you luck and the determination to do it.
