Hey, here is an idea for you. I used this (in the opposite direction) and it worked for me. I used to chew copenhagen like a fiend. 2 cans every 3 days. Night and day, sleep, eat, ALWAYS chewing that shit for 15 years I did it. Could NOT quit after several attempts. So I smoked for a couple months then stopped cold.
Dip some copenhagen for the nicotine then it's just the habit of smoking you need to get over, but you got ganja for that now, don't you.....
Just a suggestion.
Fukkin tobacco should be a classified as a class 1 controlled substance and made illegal as much destruction it causes...... I hope you can and will quit that shit!!
