I actually did a little google search on this just to learn more before pulling it out and discovered that Black Nightshade is edible, and is sometimes confused with Deadly Nightshade, which is poisonous. Here is a link:

....The issue of the edibility of black nightshade (Solanum nigrum) came up in the comments on our post on forager Pascal Baudar. We’ve blogged about the confusion between the edible Solanum nigrum and the toxic “deadly nightshade” or Atropa belladonna in a post last year. But Pascal left a link to an excellent article by author and forager Sam Thayer that puts in the nail in the coffin of the myth that Solanum nigrum is poisonous.

Unripe (green) fruit of Solanum nigrum does contain solanine and should be avoided, but the ripe fruit is perfectly edible and quite delicious. People all around the world eat Solanum nigrum. In parts of the US Solanum nigrum are made into pies. I’ve snacked on Solanum nigrum berries from the backyard and I was lucky to be served Solanum nigrum prepared in a balsamic reduction sauce by Pascal’s partner Mia Wasilevich…and I’ve lived to tell the tale! .....
And here is a more extensive article explaining the myth and confusion:

Wikipedia has conflicting information, which adds to the confusion. Never knew a volunteer weed could cause so much
