@Smoky Blue I think smell/taste are a genetic thing. The smell of skunk no matter how strong, has ever made me hurl. But most people literally puke if the odor is very strong.
I recently bought some caramel apple juice from vapemall and I can't smell or taste the caramel in it. Not even with the bottle to my nose. My beautiful wife however, can smell it across the room. She has smoked about as many years as me, but half or less as heavily. Smell, IMHO is extremely genetic. Even how intense we smell/taste something, the amount we can smell/taste is different between two people. Then add in anything artificial, that too is left to genetics how we perceive it.
Myself, I enjoy strong flavors, such as very dark coffee, dark beers (when I drank), strong tobacco, and dark chocolates. Most likely the reason why I enjoy those things most, is because my sense of smell/taste is not as receptive as other people, or, I just taste/smell those things differently. I very much dislike the smells of things like flowers and most perfume women use. Those odors are strong and turn my stomach.
