Cows Fed Hemp Produced Milk With THC, Researchers Say (washingtonpost.com) 71

Dairy cows fed industrial hemp produced milk with detectable levels of the buzz-inducing molecular compound THC, according to a new study from Germany that could influence the potential uses of hemp as an ingredient in animal feed. The dairy cows also showed behavioral changes -- yawning and salivating a lot, moving a little unsteadily on their hoofs, standing in one place for a protracted period, and having a "somnolent appearance." The Washington Post reports: The peer-reviewed study, conducted on Holstein cows in Berlin and published Monday in the journal Nature Food, is one of the first major investigations of the use of industrial hemp as a potential supplement in animal feed. For now, such use is illegal under U.S. law, which does not allow THC in the food chain. But the new research comes as hemp, which has many industrial uses, continues to emerge from an agricultural exile that dates to the "reefer madness" hysteria of the 1930s. [...]

The researchers at the German Federal Institute for Risk Assessment found no behavioral change in cows given the entire hemp plant, which contained very low levels of THC. Only when fed solely the portions of the hemp plant with higher THC concentrations -- including the flowers and leaves -- did the behavioral effects appear, according to the study. Those effects included slower heart rate and respiration, "pronounced tongue play, increased yawning, salivation, nasal secretion formation," and reddening of a portion of the eyes, the report states. Some animals "displayed careful, occasionally unsteady gait, unusually long standing and abnormal posture." The animals also ate less and produced less milk, according to Robert Pieper, head of the department of food chain safety for the institute and co-author of the new paper. "That is a strong effect on animal health. Not a positive effect," he said. But he did not predict how it would play out in the policy world.

      Drugs are good, drugs want to be free.

      Just two cannabis plants can supply one human for an entire year! There's a two plant per adult in the household limit in Canberra, Australia. This should be the global model for cannabis law reform.

      • What are marijuana's effects?
        https://nida.nih.gov/publicati... [nih.gov]

        Many people experience a pleasant euphoria and sense of relaxation. Other common effects, which may vary dramatically among different people, include heightened sensory perception (e.g., brighter colors), laughter, altered perception of time, and increased appetite.

        Pleasant experiences with marijuana are by no means universal. Instead of relaxation and euphoria, some people experience anxiety, fear, distrust, or panic. These effects are more common when a person takes too much, the marijuana has an unexpectedly high potency, or the person is inexperienced. People who have taken large doses of marijuana may experience an acute psychosis, which includes hallucinations, delusions, and a loss of the sense of personal identity.

            It's what people use to function normally in daily life. Like looking left and then right when crossing the street. And not forgetting what you just saw to the left. And then some of those short term memories have to be committed to long term. An inability to do this while being able to access existing long term memory is something that weed shares with elderly dementia.

      Sadly the "The animals also ate less" part of the result kind of deflates that joke a bit. Maybe someone will make a play for an ignobel prize by studying why stoned cows don't get the munchies. My theory is that it might be because the stuff cows eat just takes so much work - a lot of chewing and multi-stage digestion, and stoned cows just can't be bothered to put in the effort :).

        The main psychoactive component of cannabis, tetrahydrocannabinol (THC), is excreted into breastmilk in small quantities. The duration of detection of THC in milk has ranged from 6 days to greater than 6 weeks in various studies. Concern has been expressed regarding the possible effects of cannabis on neurotransmitters, nervous system development and endocannabinoid-related functions.[1,2] A 1-year study found that daily or near daily use might retard the breastfed infant's motor development, but not growth or intellectual development

    • by Anonymous Coward

      AFAIK, there is still a small amount of THC, even without manual decarboxylation. If a cow eats a huge amount of hemp, it might have enough to produce effects. Also, cows have a very different digestive system than a human which might also help with decarboxylation.

        Really?

        Hemp varieties contain virtually none of the prerequisite cannabinoids that can form THC, even after decarboxylation. And absent that essential process, they can't even get a Fly High.

        This is complete and udder cowshit!

        And notice they said "measurable". If you're "Researching For A Result" That number goes way below the "therapeutic dose" level!

    • There's a better question: how are the cows synthesizing THC - considering hemp doesn't contain any?
    • by Shaitan ( 22585 )

      Decarbing converts intermediates to delta-9 slightly increasing its concentration but most of the THC is delta-9 in the first place. The need to 'activate' is mostly a myth built on a seed of truth. It will certainly make a notable difference at scale or with concentrate.

      That said, toss some hemp in a big pile and it will decarb naturally anyway.

  • Shameless hit job on industrial hemp.

      Sounds like normal cow behavior to me.

        Former dairy farmer here, not normal behavior. Cows do yawn, but not often. Cows are quite stable when walking. Slippery cement barn floors are their biggest worry. But out in a pasture they walk very steady. I've seen them on 45 deg side hills without any problem where I have trouble walking. They'll go up and down steep slopes with ease. Only time I've seen them unsteady is after birthing they lose calcium and can get sick. As far as standing in one place, they don't do that unless locked in (as in some old style barns). In their natural habitat (outside) they normally graze- eat grass, and walk slowly while doing it, or when tired lay down for a rest. All of those noted behaviors are actually quite interesting as it could translate over to what the drug does to humans.

        • As far as standing in one place, they don't do that unless locked in (as in some old style barns).

          They will stand in one place if there's good eats there. Otherwise, sure, I was just going for a funny.

            In a grass field there's only a relatively small amount of grass that you can physically reach without having to move slightly, so a cow that's eating won't stand in one place for very long.

        • Without a mind like a scythe to hone, weed makes for poor grass for rumination. I used to run up and down Mt. Healy Alaska a few times a week. At the top I'd smoke a bowl before flying, skipping, floating and teleporting back down the trail with supernatural ease. (Denali class of 94/95/96)
    • Industrial hemp, at this point in time, seems to be hitting itself fairly well without help. 4 years ago the government signed a "farm bill" to make it easier to produce, and so they've been producing a shitton of CBD. But when the hyped demand for CBD didn't materialize, they needed a way to dump the product.

      It turns out it's easy to synthesize things like delta-8-THC and THC-O-acetate from CBD. So they've been doing that, putting it in vape carts, and dumping them in states that haven't legalized real we

For better or worse IDK, all I can say is I would rather use cannabinoids than opiods and benzodiazepines. PTSD especially nightmare related are dramatically affected in a positive way as less dreaming is one major side effect. So nice that science is finally moving forward.
    • I can second the dreaming part, THC definitely makes you dream much less.

    • Opiods cause chronic constipation. Benzedrine? My great aunt Mabel took prescription benzedrine her whole life, and lived into her 90s, so I'm thinking it's not that bad for people. Still not clear on what kind of condition a doctor prescribes speed for. I knew THC was helpful for PTSD, but you seem to be suggesting a reason why it's helpful -- less dreaming.

  • I would think if you feed cattle something that has lower nutritional value, they might appear less healthy, and have weird behaviors like salivating (from increased cud cycling), being unsteady, and general malaise.
    Meanwhile, when you feed them a mixed diet including the THC bearing parts, they are perfectly healthy. I wonder who paid to design this study.
