Wild Marijuana?

While looking up some information on Virginia Creeper (Parthenocissus quinquefolia),  I discovered that some confuse this rambling native vine with "Ditch Weed" or wild marijuana.  Although a bit curious, I didn't google further any information on the wild intoxicant, but did wonder who would be so desperate as to smoke a weedy vine growing in a ditch.

The vibrant red leaves look stunning against the white building

But back to my main search.  I think I was most interested in confirming that the vine that I had studied all summer climbing outside one of my office windows was not the five-leafed poison oak which it resembles, but actually Virginia Creeper.  Now with brilliant burgundy-red leaves, this vine catches my attention each time I pass by.   I was excited to verify that it was indeed Virginia Creeper and, thus, a candidate for my own Hamptons Garden next year.  My pool equipment shed would look gorgeous cloaked in this autumn red some day.  

I am so relieved to learn that this vine is just an ornamental beauty and not an itch-inducing weed.   However, a few may be disappointed to learn that it isn't that other kind of "weed" either.
