What are some common pathological findings associated with drug overdoses?

Pathological findings associated with drug overdoses often include pulmonary edema and liver enlargement. In many cases of overdose, substances can cause significant stress on the body's systems, leading to fluid accumulation in the lungs, known as pulmonary edema. This condition can result from respiratory distress or cardiac complications due to the effects of the drugs, which can vary widely depending on the substance involved.

Liver enlargement, or hepatomegaly, can occur because many drugs are metabolized in the liver. In cases of overdose, the liver may become overwhelmed with the substances and show signs of damage, inflammation, or fatty changes. These pathological changes can be crucial in determining the cause of death and understanding the severity of the overdose.

The other options, while they may relate to different aspects of forensic pathology, do not specifically highlight the common pathological findings associated with drug overdoses as effectively as the presence of pulmonary edema and liver enlargement.
