These kind of articles always seem odd to me. I've used an e-cig to stop smoking. Worked myself down from 21mg juice to 3mg, step by step. Now I really only use it when I'm out drinking, to prevent myself from wanting a cigarette (old habits do die hard, after all)

The e-cig helped, but the real motivator is that I wanted to run and play soccer more effectively. Vaping was just a tool that kept me away from cigarettes.
