Do you mean 1.8% like from Puresmoke? Not sure what mg that equates to. Or do you mean 18mg?
(At Puresmoke they have 5 strengths: 0.0%, 0.8%, 1.6%, 2.4% and 3.2% which correlates in mg to 0mg, 8mg, 16mg, 24mg and 32mg of nic per ml.)
Anyway - juices! My top favorites are Backwoods Brew (esp Peach and Casablanca) and FreedomSmokeUSA. FreedomSmokeUSA has tons of flavors including lots of tobaccos, their normal sizes are very configurable. They do have some of their flavors as $2.25 samplers but those are fixed pg/vg and 24mg. Their normal sizes in the other sections start at $4. Usual discount code freedomsmokeusa for 10% off. My fave FSUSA so far are Desert Ship (Turkish blend tobacco), oRYental 4 (their sweet RY4 tobacco), chocolate (not great but I mix with other flavors in the cart including tobaccos), Almond Pleasure (like an Almond Joy), and I sometimes vape their Vanilla Tahity (not much TH but nice and a good blender too)
My other two faves are VelvetVapors (closed right now but their Vanilla Almond Tobacco in their Velvet PG/VG blend is the most delicious juice I've ever had. And their Raspberry Gingerale is like really vaping ginger ale). And Gourmet Vapor because I like to play with their juice creator (mix your own flavors) even though it is difficult when you don't know how weak or powerful each flavoring is. Still tons of fun. Out of 6 juices I created 2 came out decent so I made them make public there (Morgans Eggnog and Spiced Peach Rum - but warning I go heavy on the rum flavor at 20%). My other 4 juices came out awful because of my flavor combinations but I had fun making them. BTW - if you want to search their Ejuice section, search for a flavor ingredient like Vanilla and press Search (don't just hit enter or the search won't work).
