I helped a friend quit vaping with the nicotine patches for smoking. I had to do some math because a vape hit is not 1:1 with a cigarette hit, and found that the highest dose of a patch was too low for her to start, and had to start with a few max dose patches.

Those patches aren't cheap, albeit neither is the addiction either, but just like the jump from cigarettes to nicotine gum is a good jump, so is vape to cigarettes sometimes. It was a long and painful journey for my friend even with my help, so I don't envy anyone with it worse than her (or even less of the addiction)
