When I was 15 I collected a shitload of morning glory seeds from my yard, although I don't know what breed/species/whatever they were, and I used an old coffee grinder to get them into a powder. I then poured the whole mess into a water bottle I'd painted black, added water, and hid it in a drawer for a few days. Needless to say, I nearly threw up trying to drink it, and I didn't even get any effects.
Who knows, maybe NVA morning glories don't have much LSA in them, or maybe I should've used alcohol as a solvent.
