GRACE: So that rumor is absolutely false. Thank you, Dr. Perper, for clearing that up. Dr. Perper, were there needle marks on her body that would have suggested she had injected narcotics?
PERPER: No. One of the findings in an individual (INAUDIBLE) chronic intravenous addiction, which mean they inject themselves drugs, is they develop line of scarring due to repeated injection in their arms, their extremities or somewhere elsewhere in the bodies, and there were no such marks on the body.

So I don't know if this means no needle marks or just no chronic intravenous addiction. Not clear what he means. On another board someone is speculating about a needle mark in the mouth that would be diificult to detect. Ugh.
I remember him saying she had no needle tracks on her arms.
