TOXICOLOGY AND POISONS
A poison is a substance capable of causing illness or death
"All substances are poisons; there is none which is not a poison. The right dose differentiates a poison and a remedy."- Paracelsus(1493-1541)
Why poisons are difficult to detect
Weakness,dizziness,odd behavior,headache,shortness of breath, and in extreme cases coma or seizures.
Cyanide can be identified easily during an autopsy because the body will smell of almonds, this will only work if the ME knows that is a distinct trait of cyanide.
