For some, you're right, but not everyone. When I was trying to quit smoking for the millionth time I gave ecigs a whirl. Started with those Blu ecigs weak but proof of concept so went to an actual vape shop got something that produced more of the same feeling in the lungs but was still not strong enough. Finally switched to a "cloud chasing" device and finally the same choking sensation I had from analogs was achieved and finally quit smoking cigs then quit vaping after halving nicotine til it was zero.
For me it helped quit smoking and I didn't do it all over indoors didn't even do it in cars when the kids weren't there.
When used to quit smoking it works and after switching is way easier to quit than smoking and it's 40,000 other chemicals you get addicted to.
Oh and to top it all off no disgusting smell that gets in everything like smoking cigarettes. Fuckers smell like shit even when they aren't smoking
