The problem of drugs/contraband has always been a social problem plaguing the world. Although the world is trying its best to combat drug/contraband crimes, manufacturing, trafficking and abuse are still prevalent. At present, there are many methods for drug detection, but there are few efficient rapid detection methods. Raman spectroscopy technology is favored due to its fast detection speed, ability to fingerprint drug molecules, and small sample consumption. It will play an important role in promoting on-site drug/contraband rapid inspection and drug driving screening. It helps law enforcement agencies better carry out detection work and build a solid national security defense line.
