Veterinary anaesthetics have become more widely used as recreational drugs over the past ten years. This study's objective was to provide evidence of "Anastacia de caballo" (xylazine) consumption among drug users in human and its effects. The two focus groups were held to talk about the specifics of xylazine use, its effects, and usage knowledge. 80.7% of people used xylazine regularly. More than 42% of the sample utilised speedball and xylazine together. Although injections were the primary method of xylazine administration, 14% of patients also reported using the drug inhalation ally. Skin lesions were reported by more than 35% of the sample, and at least one overdose incident was reported by 21.1%.
