Poppy seeds won't do dick (except make a loaf of bread really tasty if you sprinkle them on the dough before baking), the bit of the poppy that contains opium is the latex secreted by the seed head wall when pierced. the way to get opium from poppies is grow them & score the heads when the petals fall off, then scrape off the dried latex next day. Morning glory seeds is a different matter, they do contain lysergic acid amide and are kinda a poor relative of LSD. If you're buying them, you'll need to get rid of outer surface of the seed coat, cos they spray them with noxious chemicals - rubbing on an emery board/fine sandpaper works.
