A friend who once worked nights in a resort bar was asked by a patron where to find “weed.” As it happened, my pal’s day job was farming, and his truck had plenty of hay chaff, so as a prank he bagged some and gave it to the grateful chap. The next night the guy wanted more, claiming it was great, much to my friend’s surprise. “Who knows what else might be growing in the alfalfa,” he quipped to me with a shrug.
My first thought was that it could have been catnip (Nepeta cataria), a member of the mint family which has marked opioid-like effects on cats, and mild sedative effects on humans. It can be found in many herbal tea blends designed to help with stress or insomnia. Native to Europe, Africa and Asia, catnip long ago became naturalized in the Americas, and now grows pretty much everywhere except for the Arctic and high elevations. In fact, if you live in the country, you likely have some growing on your land.
