César Raúl González Vaca

César Raúl González Vaca is the director of the Medical Examiner's Office (Semefo) in Baja California, Mexico. He has been vocal about the rising issue of xylazine, a veterinary anesthetic that is increasingly being mixed with opioids and other drugs, leading to a spike in overdose deaths in the United States. In a recent interview, he expressed concern that Mexico is lagging in identifying and responding to the dangers posed by xylazine, which has been termed 'zombie drug' due to its lethal effects. González Vaca's insights highlight the urgent need for health authorities in Mexico to start monitoring and addressing this emerging public health crisis.
