yeah i ate two cookies yesterday and it was a bit strong...i probalby shouldn't have gotten too stoned (a girl died in my school last week and i've been a little edgy)...anyways i freaked out a little bit but it was definitely awesome. umm all i can really say is what everyone else has said....it takes about an hour to come on, then you get a little stoned, then i hits you like whoa, and for me it lasts until i sleep it off. much better than smoking...but i don't know too much about side affects of eating herb.
