hey, i was thinking about trying morning glories a try. I've read a lot about them on here and erowid, and they sound interesting. the only thing is i don't konw what kind to get. i know i should get untreated, but do they have untreated at walmart, or do they only have treated. also, should i grind them, or no. would i be able to use a pepper grinder to do that? please give some advice.
