In terms of sleep, it stands to reason that a less anxious animal is going to be more ready to fall asleep than a hyper-vigilant one. Additionally, though, there’s evidence that CBD, in its interaction with the endocannabinoid system, can help establish and maintain a healthy sleep/wake cycle — which is what tells both humans and animals when to feel sleepy and when to be awake.
Additional clarification to the law came in 2018, with an updated version of the farm bill. The 2014 law set the foundations for hemp-based products to emerge, but there was still some confusion as it did not specifically mention CBD products. This new version of the farm bill keeps the same restriction on THC, but makes it perfectly clear that CBD vape juice and all other hemp-derived products are legal throughout the United States.
