RE:RE:canadian society of forensic scienceThe CSFS is an unbiased 3rd party, their only interest is the science. Technically, the oral fluid test science is sound, just not to our standards. 2-3 day window, nurses on hand at police stations across the country ready to take a pint of blood, 10-15 minute roadside testing results, shall I go on? How do I express laughing hysterically? 2hr window, get there. We’ll polish the trophy and await your arrival mass spectrometry. Boom goes the dynamite.
