Tobacco is also a member of the nightshade family and eggplant, like tobacco, contains some nicotine (although in a much smaller amount). Eggplant has the highest level of nicotine of any vegetable, but you would still have to eat 20-40 pounds of eggplant to equal the amount of nicotine you would get from one cigarette.⁠ ⁠ ⁠ ⁠ ⁠ #eggplants #science#vegetable #biology #sciencefacts
