It is, however, unclear to what extent individual cannabinoids from industrial hemp transfer from the feed into products of animal origin and whether they pose a risk for the consumer. Here we present the results of a feeding experiment with industrial hemp silage in dairy cows. Hemp feeding included changes in feed intake, milk yield, respiratory and heart rates, and behaviour. We combined liquid chromatography\u2013tandem mass spectrometry-based analyses and toxicokinetic computer modelling to estimate the transfer of several cannabinoids (\u03949-tetrahydrocannabinol (\u03949-THC), \u03948-THC, \u03949-tetrahydrocannabinolic acid, \u03949-tetrahydrocannabivarin, 11-OH-\u03949-THC, 11-nor-9-carboxy-\u03949-THC, cannabidiol, cannabinol and cannabidivarin) from animal feed to milk. For \u03949-THC, which has a feed-to-milk transfer rate of 0.20%\u2009\u00b1\u20090.03%, the acute reference dose for humans was exceeded in several consumer groups in exposure scenarios for milk and dairy product consumption when using industrial hemp to feed dairy cows.<br \/><\/span><\/p>\n<p><span style=\"color: #333333;\">For complete research click&nbsp;<a href=\"https:\/\/www.dalgarnoinstitute.org.au\/wp_site\/wp-content\/uploads\/2022\/11\/Transfer_of_cannabinoids_into_the_milk_of_HempFedCattleTHCPoisoning2022.pdf\" target=\"_blank\"><b>PDF Here<\/b><\/a><br \/><\/span><\/p>\n<p><span style=\"color: #333333;\"><b>Also see<\/b><br \/><\/span><\/p>\n<ul>\n<li><a href=\"https:\/\/www.dalgarnoinstitute.org.au\/wp_site\/cannabis-sativa-hemp-seeds-d9-tetrahydrocannabinol-and-potential-overdose\/\" target=\"_blank\"><span style=\"color: #333333;\">Cannabis sativa (Hemp) Seeds, D9-Tetrahydrocannabinol, and Potential Overdose<\/span><\/a><span style=\"color: #333333;\"><br \/><\/span><\/li>\n<li><a href=\"https:\/\/www.dalgarnoinstitute.org.au\/wp_site\/is-your-beef-grass-fed-or-weed-fed-industrial-hemp-in-food-chain\/\" target=\"_blank\"><span style=\"color: #333333;\">Is your beef \u2018Grass Fed\u2019 or \u2018Weed Fed\u2019?
