My mother inlaw was a smoker for 30+ yrs untill recently. She tried then new drug Chantix. She has been smoke free for 3 1/2 months now. Im not sure if you can used this for chewing or not. As soon as I find out if my insurance covers this stuff I am going in and getting some. I figure its time for me to stop too. Im sick of going outside or in the back porch in the cold to smoke. I have been smoking a pack a day since I was 14 yrs old, aughhhhhh, now Im 28. Yup def time to quit.
