How am I supposed to describe why I think that? I can't dig through my brain and go "why do you hate this smell" I just do. Why does it matter what specific tar it is? Are there even different tars?
I like the smell of lavender, it smells fresh and clean, it reminds me of nature and good memories of maintaining a garden. I like the smell of cigarettes because i affiliate it with a relaxing moment, the smell is stuffy and i find that comfortable. I dislike the smell of lotus, it feels very strong, pungent, and chemical.
That is how you describe scents. Heck you could've just Googled how to describe scents and you'd get over 30 words just to describe scents.
Also yes there are different type of tars, you think they put the same stuff in cigs that they make roads with?
