I have a friend who has been using an e-cigarette for 10+ years. He doesn't seem any less addicted to smoking as back when he was using old-fashioned cigarettes.
I understand e-cigarettes are supposed to help you quit... but has anyone actually had success with them? Or, is it more like trading one vice for another?
It worked for me, but the intent was to quit. Your friend isn't trying if it's been more than a decade. I started at a higher nicotine, and slowly got lighter nicotine options. Once I got to 0 nicotine, it was mostly just breaking the physical desire to do something when my hands were free or while driving. I think I only bought one bottle of 0 nicotine and moved on.
Same, I switched from smoking to vaping a pretty high nicotine juice at the height of the vaping craze. Slowly worked my way down to 0 nicotine and finally was able to drop the vaping. I haven't had a vape in over a year and haven't had a cigarette in about 5 years. I still get cravings but they pass and I'm fine. I was a pack per day smoker for 20 years, e-cigs can absolutely help if your intent is to quit.
