I was a dedicated Newports smoker for 33 years. Tried other brands and always went back to Newports. When I started vaping, I tried many menthols and many "NuPort" varieties. Only one came close for me:
10ml bottle of Nuhport flavor e-Liquid I am fairly certain it is a China juice and PG. Within a month or so I moved on to others that I liked better. When you start vaping full-time (as in no more analogs), your taste-buds change and your sense of flavor comes back. So after about a month or 2, I did not want that juice anymore.
I still have several tobacco menthols that I enjoy but I stick with US made and really prefer higher VG base mixes. One that I found early on, that is still higher PG but is USA made and is still one of my favorites it the Tobacco Menthol from Tasty Vapor:

Another great tobaccos and tobacco menthol juice mixer is Vaperite. He has a Menthol Maker that lets you choose the tobacco base and the menthol level. Some are macerated and others use flavorings. Vaperite makes bout 60+% of my favorite top-line-up juices in my collection. He also has sample packs. From the MEnthol Maker, my 2 favorites are the Burley Menthol and the Organic Tobacco menthol. I use the medium menthol level. You can see the Menthol Maker here:
Menthol Maker Vape Juice He has MANY awesome juices.
But, if you are really still very new to vaping and obviously looking for that Newport experience, Try the one from VaporKings as a starting place and when you are ready to branch out, try the other two for top quality juices.
