Smoking it provides an instant lung hit of nicotine which rapidly goes to the brain.

Gums,patches,etc.. are all slower releases of smaller amounts.

your not just addicted to nicotine your addicted to it in a huge lightning bolt dose method. same reason a heroin addict could have a very hard time getting relief by taking large quantites/varieties of scripts orally. he doesn’t just need the chems he needs the delivery time upgraded to rapid express as well.

It is however a million times healthier as the tar and by products of combustion (smoke) is what kills you and makes you feel like tired. If you did use NRT your lungs would be healing all the same and that is the most important thing.

Very pricey for profit thing. Use it if you need it because using anything is better than continuing to breath smoke and if you got the balls (need very very steel like ones) go cold turkey.
