I did it a while ago! Back before juul and everything, when it was more common to build your own vape rig. Had a mind to quit just combustion at first. It stank and stained things yellow.

Went from two packs a day to vaping, and it was pretty easy to transition. Maybe a couple days of feeling a bit weird, but not really any more so than simply switching cigarette brands. I immediately noticed huge benefits. Made it a lot easier to breathe, for one.

After a couple years without cigarettes I eventually had a mind quit vaping as well. To be honest I wasn’t having any serious issues with it per se, actually the main impetus for me to quit came when I was planning a big camping trip. I was extremely anxious about potentially losing the device out on the water, or dropping it out on the trail, or not being able to charge it. Then all at once I realized I really didn’t want to be carrying this device around forever.

So I just quit cold turkey one day. Busy Friday at work, and a couple hours had gone by and I worked through my smoke break without realizing it, and I was like, “hey today’s a good day to try, let’s see what happens”

It was brutal. I couldn’t sleep the first night. Felt like my lungs were wrapped tight in barbed wire that was squeezing tighter with every breath. Soaked my sheets though with sweat. Sunrise came and went and I just sat there all morning clenching my sheets. Skipped eating, couldn’t focus on anything. Passed out at like 4pm. Woke up at like 11, drank some water, went back to bed. In the morning the barbs felt a little looser, and morning after they were looser still. And then I was alright

I still carried the thing around for another few months. Kept it charged. Held onto it while I drove. Actually the first time I left home without it I had a wave of anxiety. Even after months without using it once, the thought of not being able to was still a huge wall to overcome.

When I think back on it, I’m actually kind of stunned that I managed to quit at all. Which brings me to the OP,

The Cochrane team looked at 80 major trials involving nearly 30,000 people and found that nicotine vapes were more effective than traditional aids such as patches, gum and support plans - increasing the success rate by about 60%, from around six in every 100 managing to quit smoking to one in every 10.

I suggest doing everything in your power not to begin using nicotine in the first place, kids!

increasing the success rate by about 60%, from around six in every 100 managing to quit smoking to one in every 10.

So 4% of those trying to quit cigarettes manage it with vapes who would otherwise have failed.

Meanwhile a full 10% of the population vapes regularly and "the long-term risks of vaping are not yet clear".

They'd have to be pretty harmless for this not to be a net detriment.
