I've been happily vaping away on my Inferno setup for several years with no problem. Love the product, love our local store/coffeehouse.
I recently switched to the new BCT setup and out of nowhere I started getting canker sores, the sore tongue and palate thing, etc. It's very very painful.
I've been using the same juice for a very long time in several sorts of setups (it's a 50/50) and had no reaction to it at all. I even cut my juice with more glycerin to lower both the nic and PG levels to see if that would help....no dice

WTH?
