Poisonous plant/weed

Christine
by Christine
I recently saw a post about a plant/weed that has been deemed extremely poisonous here in Michigan. You were not even to touch it because of the toxicity. It can make you go blind and/or even kill you. Has anyone seen this posting? I need to see it again. I may have this growing in my flowerbed and need to know what it looks like before I all authorities. Thank you everyone
