The most dangerous products of modernity often reach poor communities stripped of their warnings and context, so people meet them as beautiful, magical or valuable objects. The harm spreads through curiosity, generosity and trade, not ignorance alone, because the thing's appeal is exactly what carries it into homes and bodies.
