Don't do this without a thorough soaking! Morning glory seeds possess a toxic chemical that will make you sick it you eat them dry. The chemical is converted when the seeds are soaked overnight and start to germinate (the same process one would use before planting to speed the growing process). If you don't do this before ingesting morning glory seeds, you'll most likely end up vomiting.

And I generally don't endorse eating morning glory seeds for psychedelic effects anyways, can't plants ever just be left to be beautiful on their own without people trying to figure out how to get high off of them?
