Human Rights Watch says children as young as 7 are working long hours in U.S. fields harvesting tobacco under sometimes hazardous and sweltering conditions.
The group interviewed more than 140 children working on farms in North Carolina, Kentucky, Tennessee and Virginia and says they report symptoms consistent with acute nicotine poisoning from absorbing nicotine through their skin.
The report acknowledges that most of what it's documented is legal under U.S. law.
