You wouldn't have to worry about mushroom poisoning if you grow your own. Check out the pennington birdseed tek. If you can't find spores, then I think a manure tek would work without spores if I'm not mistaken but I think manure would produce different mushrooms also. So the risk would mimick picking. I guess I'm one of the oddballs that prefer lsd over fungus. I like the entergetic/electric body high that lsd gives opposed to the sedated feeling of shrooms.
