just for what it's worth, i personally get nicotine salt juices for use with my sub ohm tank. i never really got the appeal of those small vape pen style ones like the ego or the modern wave of juuls. but i have heard some people say you can't do nicotine salt ones or shouldn't with a sub ohm vaporizer. i still don't see why. the reduction of throat hit with a large delivery of vapor seems to be the ideal way to consume it for me
