Reading this thread has me wondering if maybe the cinnamon flavor I tried was an accident in the mixing room because it was downright disgusting. I must try the Atomic Cinnacide that Pam must like so much to have used for 3 years straight, just as an experiment to answer a few questions I have concerning differences in taste sensation from one person to the next. I'd have to agree with alex because what I tried was so overpowering that I couldn't imagine how anyone could stand to put that stuff into their mouth all day long. It was like putting a big spoonful of cinnamon powder into my mouth and then trying to choke it down or something. I also wonder if the condition of an individual's taste buds have something to do with how bearable they find any very strong flavors, because I must say that some of the stronger flavors, even the ones that I like to some degree, become a bit more than I can take after a while because to me it starts to feel like my taste buds are being assaulted and I have to stop. I know that my taste buds must have been damaged to a great degree from 45 years of cig assault, but just how much is hard to say. I don't remember exactly but I did read something to the effect that a person loses half of their taste buds by a certain age, so it's obvious that the younger someone is the better they should be able to taste.
I get the impression from posts I read on this site that some folks either have taste buds that have been virtually destroyed and need super stong flavors to taste at all, or perhaps some individual's can taste certain substances to a much larger degree than other individual's. I watched a number of reviews of a particular e-juice on youtube and was amazed at how so many of the reviewer's seemed to be completely unable to describe the flavor, so-much-so that it was obvious to me that they simply couldn't taste anything at all! It was for a flavor that I had tried myself and was able to pick out a number of different flavors and felt quite strongly that I had them nailed, at least to my satisfaction, even though I know that I may have been mistaken to some degree.
I have a sample of Atomic Cinnacide on order, so good or bad, I'm going to find out if cinnamon is a flavor I can tolerate or not.
