A man rests in a room at the old Hotel Migrante, which used to be a shelter for migrants but now houses mostly homeless people with drug use problems, in downtown Mexicali, Baja California State, Mexico, on May 8, 2023. Following the discovery that heroin is being cut with fentanyl, an opioid that lurks as a global threat, ONG Verter created La Sala, a safe place for vulnerable heroin users in Mexicali -in the Mexico-US border- to consume and avoid overdose.
