Not really though.

White Zetsu clones aren't just "drained humans", they were also remade into living puppets of sorts by the Divine Tree. Given that the thing that made them was a source of Wood Release (i.e a sentient tree), the White Zetsus may have inherited the Wood Release power from there with Hashirama's DNA simply serving as a buffer.
