Children working on tobacco farms in the United States are exposed to nicotine, toxic pesticides, and other dangers, Human Rights Watch said in a report released. While US law prohibits the sale of tobacco products to children, children can legally work on tobacco farms in the US. The world’s largest tobacco companies buy tobacco grown on US farms, but none have child labor policies that sufficiently protect children from hazardous work. The report, “Tobacco’s Hidden Children: Hazardous Child Labor in US Tobacco Farming,” documents conditions for children working on tobacco farms in four states where 90 percent of US tobacco is grown: North Carolina, Kentucky, Tennessee, and Virginia. Children reported vomiting, nausea, headaches, and dizziness while working on tobacco farms, all symptoms consistent with acute nicotine poisoning. Many also said they worked long hours without overtime pay, often in extreme heat without shade or sufficient breaks, and wore no, or inadequate, protective gear.
