This "crisis" is the equivalent of designing the perfect ass-kicking machine. Then, the users complain because they are getting their asses kick at previously unknown levels. JUUL ended up being the scapegoat for all vaping, but not having the choice of nicotine levels was a bad choice. You had that choice in do-it-yourself "messy" products, but, in the end, it's still a nicotine delivery system. These guys did what they set out to do, but ended up not having the foresight to realize what their product would actually be used like...and marketing to kids was the smoking gun, pun intended. Kids are too gullible to be using this.
