Yes to 12 mg. And a very big yes to losing some flavor. For me, the flavor is the important part of this whole process. Without it, it's just making a white vapor clouds. We've all had the idea to cut liquid to make our dollars stretch and the solution is get flavor concentrate to add to the diluted mix. This may lead to you becoming a diy-er but you get to keep a great flavor without sacrifice. Or buy 0 nic juice if the nic is too high. Hope it helps.
