"A natural painkiller more powerful than morphine has been discovered in human saliva, and may lead to improvements in the clinical treatment of pain, French scientists say.
The compound, called opiorphin, acts on pathways involving not just pain, but also emotional responses, according to the researchers."

It is very interesting that we are still finding new potentials from the human body. Boy do we have a long way to go yet.
Maybe CB will start to discriminate against people who have to much opiorphin as they could be considered drug addicts.
