Yes I know that - but there is not any indication Anna had a IV in her when she died. So the Demerol would be shot into her tissues or directly into a muscle.
It also come in pill form - but once again no pills were found in her stomach.
Would it be possible for any of these drugs to be administered via an aerosol spray similar to a nose spray bottle or asthma inhaler? It would go right to the lungs and into the bloodstream. Very quick because it by-passes the absorption time.
Ok I gotcha...also..pills could have been taken but already digested..that would mean none in the stomach
