Vaping is evolving. But not really. The FDA had put a freeze on new products back in 2016. You may be aware of the “nic salt” fad. Nic salts allow the user to vape higher levels of nicotine, without noticing a harsh hit. Pod systems are primarily the devices using high nicotine nic salts, as they like to offer near 60mg nicotine options in a smaller “puff” of vapor.
