Does Sam demon blood drinking go back even further?

Season 3, No Rest For The Wicked. As Dean is getting closer to being dragged to hell, he's able to start seeing through the "veil" and can see the demons inside people. Well, near the beginning of the episode, he looks up at Sam and Sam's face goes all freaky. Why would it do that unless there was some kind of demon-y thing to make Dean see that? And yes, there was the demon blood from when he was a baby. But that was a teeny-tiny drop 25 years ago. I would think there needs to be something more there for this to happen.

Thoughts? Yes? No?

Right. I agree with that.

Which is what made me think drinking the demon blood is what caused Dean to see whatever he saw. But see wraith's post below...

Yeah, that's what I thought - I seemed to remember that it was a symptom but couldn't remember where I saw/heard it.
