Now ive done it. Im certifiable. I took some spearmint flavor juice and added french vanilla abot two to one ratio (mad scientists never measure exactly) and enough (lots) of salt nic base to get the mix close to 60mg/ml nic. I even added 10 drops of euro flavor burley tobacco. I made 30mls of this. I shall not be buying another pack of juul pods for a good while. This mix needs steeping with the tobacco and vanilla trying to get aquainted with each other and the spearmint. First taste is very interesting. I was going for the taste of Camel snus in their frost flavor. Its real close. Steeping will do the trick. Its actually pretty nice now but will definitely improve. I didnt go crazy with the burley as its a pretty strong flavor and i just wanted a hint of tobacco to play with the other flavors. A slow exhale definitely reminds me of those snus pouches. Im pretty pleased with this effort. So, sorry, no exact recipie yet. This is an experimental batch. Ill try to work up some percentages later for anybody who may be interested in a pod juice with crazy high nic. Im vaping a podful now as i type this and all i can say is wow.
