Earlier quoted context omitted.
At the very least, nicotine-free e-cigarettes allow people addicted to cigarettes to maintain the habit of smoking -- going outside, taking the mental break associated with cigarettes -- but without the damage of actual smoke or nicotine.
You can do this without smoking anything too. I smoked a pack a day for over 10 years and quit cold turkey without any patches or vaping. The mental break thing is definitely real. I highly recommend just going outside. Maybe do a couple of laps around the block.
We have decades of data showing that isn't the case.
