I'm been using a JUUL since back in November. Began with the 5% that came with the device, cut back to the 3% and now am using 1% and refilling the Pods. I go through maybe 2 pods a week and have stopped holding it in my hand.
They say there's 3 parts to smoking, the nicotine habit then the hand/mouth habit. I'm slowly weaning myself from the nicotine and the mouth part is about gone so I concentrate on the hand habit. I've tried masturbation but I think that's just trading one, less socially acceptable habit, for another.
IMHO... it's better than the road I was on and a hell of a lot less expensive but that wasn't my motivation......
