you sure they are seeds?
i had a pant one time with very small seed-ish looking things in the buds, but you could crumble them up in your fingers just like bud, still to this day i have no idea what they were or what caused it but they smoked fine, well it wasn't the most potent weed, just some bag seed, but it tasted fine and gave you a nice clear high, i also harvested early because of them.
not that this is of any help but just sharing an experience.
