How you identify opium?

Opium can be identified by its distinct appearance, typically as a dark brown or black sticky resin. It has a strong, pungent aroma and can be found in the form of dried latex from the poppy plant, particularly the Papaver somniferum species. Additionally, chemical tests can confirm its presence by detecting specific alkaloids such as morphine and codeine. In a forensic context, laboratory analysis through techniques like gas chromatography-mass spectrometry (GC-MS) is commonly used for precise identification.
