Do e-cigarettes actually work?
I have a friend who has been using an e-cigarette for 10+ years. He doesn't seem any less addicted to smoking as back when he was using old-fashioned cigarettes.
I understand e-cigarettes are supposed to help you quit... but has anyone actually had success with them? Or, is it more like trading one vice for another?

Link your evidence and I will critique it. I can't do anything with this hand-wavey nonsense.
There's a lot of really terrible anti-vaping research out there (as there is in any field). Like the one that claimed vapers were more likely to have heart attacks which was withdrawn after reviewers and editors demanded they state which happened first, the vaping or the heart attack.
It is a difficult area to study, no doubt. If you're relying on observational studies which show an association but cannot determine whether there is a causal arrow, or even which direction it points in, you need to be very careful about how you interpret it. You can't rely on the authors or the headlines. Pub Peer is often a useful first port of call to find any concerns raised, a citation search is also useful.
