No, milkweed is not edible by humans when fresh although yes, it is when cooked. The fresh shoots of the plant in question (Asclepias spp) offer attractive looks and healthy tastes once they are cooked. They serve as delicious ingredients in salads (that unite baked, cooked, fried, grilled meats, seafood or vegetables), soups and stews as well as in mixed vegetable platters.
Some people say you can eat the roots or the young pods if they are properly prepared but there is much better and safer stuff to eat.

The white liquid milkweed secretes when cut -- and other parts of the plant -- contain a cardiac glycoside much like the one found in digitalis (foxglove). This toxin interferes with the calcium and potassium channels, and modifies the heart rhythm. Some wild food references indicate that milkweed flowers and immature pods can be safely prepared for eating. However, I'm hesitant to trust this information. So yes -- milkweed is toxic to humans.
