I think as far as pure nicotine absorption rate(passing through the mucosa into the blood), the Indian whites come out on top due to their ultra fine grind. Finer than toasts making absorption fast. Big pinches of something like white elephant or Dholakia White or Willie Pete usually does the trick when I’m focused on pure nicotine content

In second place, I’d put the toasts there.
but that’s just my humble opinion  and everyone’s biology is different   I enjoy the toasts more for taste
