I had Alice brownies the first time back in the '70's. I had a friend who lived up in the mountains above Charlottesville, Va and he & his lady invited my wife and I to supper.
He had a big grow up the mountain from his house and he really knew his stuff about growing cannabis. This was back in the day when weed you bought was maybe 1/10 the potency of what you get these days. Well, his was easily as good as today's best herb.
He treated us to brownies after we arrived. I had no idea about edibles and ate a whole brownie. I never made it to the supper table. I awoke the next morning on the floor in front of his TV set.
That's when I learned to pace myself on the edibles!
