I did both for a while, smoking and vaping. A place I shop at was giving away cans of nicotine pouches when you bought a pack of cigarettes for a little while.

One day I was starting at the nicotine pouches and thought, "fuck it, let's add another addiction to the mix." Over three hours later I realized I hadn't even thought of a cigarette or vape yet and I didn't feel like one even though I was thinking about it then. A lightbulb went off in my head.

I think I bought one more pack of cigarettes after that. I quickly went down to a few cigarettes a day, then down to two cigarettes a day, then one for a few days, and then none. Vapes were just an indoor substitute for cigarettes, once I didn't want cigarettes I didn't want to vape, either. It took me about a month after that to wean off the pouches, too.
