As an ex smoker and now ex vaper, who wouldn't have quit cigs without vaping, Juul definitely feels to be something apart. Part of the problem, not the solution.

Their USP seems to be delivering a much higher "hit" more quickly, trying to give a hit like your first ever cigarette. Never tried one and don't intend to so have no clue how true this is, but it was definitely part of the buzz around them.

juul is a nicotine salt instead of freebase nicotine, making it unique among market offerings.

Well some regular vape mods can use nicotine salts, so I don't see what's unique. Never tried these so I have no idea why that's different as I said. Just what I picked up from the buzz around their launch about the "faster better hit".

what's unique is that juul goes at 50mg of nic, where most small operators would stop at 20mg. with step downs all the way to 0mg. juul only offers 50mg. (20mg in Europe as that is the legal max)
