I used a 'vuse' e-pod to quit smoking...
Then the government nerfed the nicotine levels allowed in the devices, and naturally I went back to smoking.
Prior to vaping i smoked maybe a pack and a half a day, since vaping, I am now over 2, 2 and a half packs a day if drinking.
Just, watch that.. they allow you to hit them with impunity and can further your nicotine addiction in a HUGE way.
