The Agrinautica

Regarding the poppies--- I've heard bees can make morphine-laced honey from opium poppies. It sounds a little far-fetched, but possible, and I know you can get poisonous honey from toxic plants. Have you had any experience with this? My uncle did have to avoid using honey from one of his hives one year when he noticed the bees acting erratically and some weirdness with the honey, leading him to conclude that they'd gotten in to some marijuana plants, but I haven't done any beekeeping myself...
