...is it a vanilla aromatic? I thought the topping was a liquor of some sort
To me, it is a vanilla cream soda flavor. It has a light topping, so it is an aromatic, but it also has some condiment leaf (perique and dark fire) that changes the aromatic effects into more of a cream soda like flavor.
To the bystanders smelling the room note, it is just a vanilla aromatic, as I have been in the room several times as others smoke this one.
