The researchers implemented what I called Raman Spectroscopy that makes a quick and non-invasive testing on the product. This is great, because this means that law enforcement would be able to test ‘on-the-spot’ whether the cargo is hemp or not. The technique implements laser light to light up certain structures within materials. The material scans are 100% unique – just like your fingerprint. In order to prove that it worked, they had to go to Colorado – at least one of the grad students had to – several times to go and test out different crops. The results came back with 100% efficiency.
