Should I try Saliva?
 

Salicule is a proprietary portable oral fluid sampling device for collecting saliva specimens for testing. Many substances can be detected in saliva specimens collected using Salicule, which include drugs, hormones, antibodies, infectious pathogens, and genetic substances. Salicule is used in both laboratory and point-of-collection (POC) testing of saliva specimens. Salicule provides undiluted specimens, which enables quantitative testing of analytes in saliva.

A substance in human saliva is being developed into pain killers some three times as powerful as morphine.
