User blog:Rapture's Daddy/Would splicing raw ADAM explain Splicer deformities?

Alright, I know it sounds like a stupid question but does using the raw form of ADAM (The Sea Slugs) explain the Splicer's deformities? I've never seen them using a Gatherer's Garden and the Splicers seem capable of only harvesting the Sea Slug imbedded in the Little Sisters. Does that mean they consume the ADAM right then and there?
