Ginger.
So I read about the Halo tobacco juices on their website:
Freedom, Harley/Torque, and Smooth 8
I got the Freedom first, and it was pretty good, tasted like ginger.
Then I just got the Torque, and it tastes like... wait for it..... ginger.
Knowing that the website does not mention ginger for the above flavors is interesting.
And even more interesting when the website says Smooth 8 tastes like ginger.
NEWSFLASH: They ALL taste like ginger.
So I guess Halo feels that ginger is what simulates a cigarette or tobacco taste.
--Torque, least ginger
--Freedom, more ginger
--Smooth 8, I assume, even more ginger
If you like ginger, these are pretty good.
I don't hate ginger, and put a whole slice of pickled ginger on my California Rolls.
But yeah, this stuff seems to be just ginger juice, in varying amounts.
They all taste the same except for how much ginger they have.
Although I say that without actually having tried the Smooth 8 yet.
JMO and YMMV
