I actually used vapes (the “real” ones) to stop smoking. It took years, but having the capability of controlling how much nicotine I had in my vape liquid was key. Eventually I brought it down to zero, and was able to stop.
This said, in europe the market is being flooded with disposable, colourful vapes - and those are an abomination. Just thinking of trashing all those lithium batteries makes me angry.
