I was a a pack - pack and a half a day smoker for 12 years. Had tried to quit for many years and had all but given up when i tried a salt nicotine vape. A month later i was smoke free, and 2 weeks after that i had kicked the vape (was never a fan of nicotine by itself, so the vape was easy to kick). This was about 2 and a half years ago now. Vapes are an indispensable tool to quit smoking.
