The hard part of switching from smoking to vaping, for me, was that it just didn't taste/feel the same to me.
In fact, it HURT my lungs. (imagine that -- after 44 years of two packs of full flavor cancer sticks, water vapor hurt my lungs. LOL)
Switching to 100% VG made a big difference (and the vapor is thicker).
I started mixing my own juice, and found I can come very close to matching the analogue "experience" with my custom juice.
Whichever tobacco flavorings you chose (and there are plenty), I've found that adding a good deal of "Bitter Wizard" to the mix (to reduce the sweetness of the VG), and just a few drops of "Butter Rum" results in a very realistic "cigarette" taste.
