Sure looks like it. AFAIK it is only toxic if you eat it, though I suppose some people could get a rash from touching it. I pick this plant to show my students at least three times a year and even have them smell it (smells pretty bad). Never had a reaction from it.

Thank you for the ID!
I'll keep that in mind and not walk through there again. :)
I didn't smell anything bad around the plant (the breeze carried a sweet floral smell actually). I guess the bad odor would be from the sap/broken plant matter?
Hm, interesting that a lot of the flora in the local park gets mowed down but they've left the entire hoard of these poisonous ones.

Nasty stuff. Dispose of it carefully if it's on your property(wear gloves, don't burn it, bag it up and send it to the landfill). Tie a bright ribbon on it so you'll know where it is and where there may be plants in the future.
