The Sinaloa Cartel and the Jalisco Cartel

Fentanyl is deadly. Thousands of Americans die every year from a drug overdose – the majority of them after using a synthetic opioid like fentanyl. Fentanyl was developed as a legal, and effective, pain killer. Now, fuelled by insatiable US demand, it’s illicitly produced in makeshift laboratories in Mexico by organised crime groups. In the first of a two-part series, Assignment travels to the Mexican Pacific port of Manzanillo. This is one of the main entry points for the chemical ingredients required to make fentanyl. It’s a town where Mexico’s powerful cartels have fought for control, and where the mayor lives under armed guard after a failed assassination attempt. Although the primary destination of Mexican-made fentanyl is the US, Mexico too has a rising number of addicts – especially in Tijuana on the Mexico / US border.
