I think the literature says tapering is more likely to be successful, but I think it depends on the type of person you are, and your reasons for quitting.

I smoked for about 15 years. I quit by breaking the habit s associated with smoking: I used nicotine pouches for a year.

then went could turkey

I still keep a tin of them in my desk drawer. I don’t use them.

I will use nicotine recreationally, but it’s not a habit any more.

You can try switching to nic pouches like zyn/velo. They’re just powder nicotine from a lab I don’t think they’re tobacco based at all. For me vaping was also a physical addiction, whenever I’m driving or on the toilet or gaming I kept feeling the need to vape. So I dealt with the routine/physical aspect first and then the nicotine.

I was doing really well for about a month but I bought a vape for a night out and it lasted 2 weeks so I gotta taper off again with the pouches.

I don’t have experience with nicotine, but coming off other substances tapering has worked best for me.

Personal anecdote but free base nic 3mg/ml was low enough I quit without withdrawal symptoms. Salt nic, what’s in most of the pods, hits harder than standard smokes for me and I had withdrawal symptoms when switching to freebase.

I was able to taper down the nicotine until I hit zero. Quitting just came really naturally once there was no nicotine. I gradually vaped less over a period of two weeks and then one day I realized that I hadn’t vaped in a few days, and that was it. Unfortunately I picked up pipe smoking a couple years later when I quit drinking because I felt completely devoid of anything enjoyable. My wife hated that so I quit smoking a pipe and started vaping again. This time I haven’t had any motivation to quit vaping. It’s the last vice I have left.

Not literature, just an anecdote from someone experienced with both ignition based and vaped nicotine;

I find a combination of both tapering off and cold turkey to be best. When I know I’m coming to a stop, I’ll eek out what I have left and then commit to going cold turkey. The first three days of no nicotine always suck the most, but after that, every day is just slightly easier, until you eventually get to the point where you realise you’re not really missing it.

Once you’ve been addicted to nicotine, you never really stop wanting it, but after a while you become ok with the idea of not needing it. The only reason I gave up was because I realised I was essentially paying a subscription to feel normal, it wasn’t even pleasurable anymore.

My best advice is never try it, but to each there own, I’d never tell anyone what should or shouldn’t go in to their body.

I’ll share one particular experience - the weakest strength juice they sell is still very, very addictive especially if you can just vape inside. I finally quit when I started mixing the juice myself and halving the strength every two weeks. One day I forget to grab my vape on the way out for the night and that was basically the end for me. My concentration at that point was more than 10x weaker than the lowest strength I could get off the shelf. So just keep that in mind if you decide to taper.
