I’ve smoked for 35 years and tried to quit smoking using nicotine gum and patches, but neither one worked for more then 20 hrs. I gave up trying to quit smoking. One night a friend stopped by with a disposable electronic cigarette and after trying a couple I decided I didn’t want to smoke anymore. I’ve been using the electronic cigarette for over a month now and the cravings for cigarettes stopped after 3 weeks so I won’t have to smoke anymore.
