What toxicologists who discovered carfentanil in adulterated cocaine said

Finally, after eight days, it was confirmed that the adulterated cocaine, which killed 24 people, was cut with carfentanil, an opioid 100 times stronger than fentanyl and 10,000 times stronger than morphine.” It is the first time it has occurred in our country, in Uruguay it was not found either, this came from the United States,” said Luis Ferrari, professor in Advanced Toxicology and Forensic Chemistry at the National University of La Plata (UNLP) and in charge of the study that discovered the substance. Ferrari remarked that “a small amount of milligrams of carfentanil means to perform many doses” and graphed: “A very small amount of carfentanil means death.” Asked about the possibility that carfentanil was tried in a clandestine laboratory to find something cheaper than importing the opioid, he replied: “It’s not that simple.” If after deepening the studies, there are many by-products, products that did not react, it is evident that it was made in a laboratory of less complexity, more homemade. If you have a carfentanil structure without other components, it will most likely come from more advanced countries,” he explained.
