Custodians of the Secretaría de Seguridad Ciudadana (SSC) detained a 48-year-old woman who allegedly tried to introduce drugs into the Reclusorio Preventivo Varonil Oriente in Iztapalapa.[1] The detention occurred during security screening of visitors to persons deprived of liberty at the prison in the Lomas de San Lorenzo neighbourhood.[1] Officers approached her after noticing evasive behaviour and carried out a preventive inspection.[1] During the inspection they found a wrapper hidden among her clothing containing green, dry herb with characteristics similar to marijuana.[1] The wrapper held approximately 125 grams of suspected marijuana.[1] She was informed of her constitutional rights and transferred with the seized material to the Ministerio Público, the public prosecutor’s office, which will determine her legal situation.[1]

Between January 2025 and October 2026, the prison system’s undersecretariat recorded 66 people detained for allegedly trying to bring prohibited substances into the capital’s 13 prisons.[1] Those seized products included marijuana alongside cocaine, crystal meth and alcohol, so the 66-person total is not a cannabis-only figure.[1] The report presents visitor screenings as a detection point for drugs entering the prisons, while noting that arrests alone do not show how much drugs enters or the scale of the supply networks.[1] Detentions do not by themselves amount to a finding of guilt, with responsibility to be established by the Ministerio Público as each case is investigated.[1]
