This paper examines the first reported case of Green Tobacco Sickness (GTS) in Poland. A 25-year-old man who worked in a tobacco field for 14 hours with no protective measures experienced symptoms of GTS, and additionally, diplopia, after leaving the field. Upon hospital admission, diplopia was no longer observed. Diplopia was most probably caused by disturbances to the cholinergic neuromuscular transmission, secondary to nicotine. These neurological disturbances, the first of their kind observed in the course of GTS, deserve special attention. The case shows a potential adverse health effect related to tobacco harvest, as most Polish tobacco plantations are not mechanized. Polish farmers should be obligated to protect their workers with protective clothing, shoes, gloves and masks. Recommendations for tobacco harvester health are put forth in the paper.
