Hemp-Fed Cows Get Buzzed, Study Finds, but Will Humans Who Drink Their Milk?
Hemp with high THC content given to Holsteins leached into their milk, according to a group of German scientists exploring the food chain for dairy production.
Do cows that consume cannabis act goofy, get the munchies and spend more time lolling about with their stoned buddies? It may sound like the beginning of a bad joke, but German researchers seeking to understand the effects of feeding dairy cows THC, the psychoactive compound found in industrial hemp, made a few intriguing discoveries, according to
a study published this week in the journal Nature Food.
Compared with cows that received the usual diet of corn and hay, the hemp-fed Holsteins were more chilled out, salivated and yawned more often, and frequently engaged in whimsical
tongue play, the study found. They also spent more time lounging around the barn as they chewed their cud and ruminated the universe. They did not, however, exhibit a proclivity for binge eating. Although the behavioral changes were noteworthy, they were in some ways the unintended consequences of an experiment by researchers at the German Federal Institute for Risk Assessment, who were seeking to learn how THC-laden hemp might affect dairy production. The scientists also wanted to know whether THC, short for tetrahydrocannabinol, could find its way to humans through milk.
Those questions are especially pertinent to American hemp growers, who have struggled to find an outlet for the roughly 24,000 tons of organic matter leftover once cannabinoid compounds like CBD are extracted from cannabis sativa, the flowering plant that produces widely divergent levels of THC depending on the cultivar.
