I bought a small 4ml bottle to try, with the idea that I'd taper down my nicotine content until I finally had the "quit smoking" liquid to use. Yes, it has a peculiar odor. Futhermore, it has a peculiar taste. This is what I imagine it would be like to smoke a cough drop. There's a stange aftertaste, too, that smacks of something used in cough drops, perhaps even metholyptus. Think of this as Vicks for the e-cig.
I've read posts from users who like this taste better than the flavored varieties. I'm not one of those, after trying it. If the choice is between non-nicotine, flavored liquid and this, I'll take the flavored. But if I don't want nicotine, why not just vaporize propylene glycol flavors from Bickford? They're $3 for 10 times the content from E-Cig (see posts in Combo Flavors). I plan to try that next: a Kahlua vapor -- finally!
I guess you read what's in the Quit Smoking liquid? Root of Kudzuvine, root Chinese of Senega, root of liquorice, breaks into leaf of blackberry, root of ginseng, bulb of lily. Kudzu? If it becomes popular, the South shall rise again.
