Industrial hemp contains, by weight, far less CBD than CBD-rich cultivars such as Harlequin or Sour Tsunami. This means that producing a single 10 mL dose of CBD would require the cultivation and extraction of far more hemp than it would from whole-plant marijuana; thus raising the risk of exposing users to more contaminants. Hemp is classified as a “bioaccumulator,” or a plant that naturally absorbs toxicants from the soil.
Synthetic cannabinoids also pose a significant risk to users because the effects can be much more severe than those produced by marijuana. Some of the compounds in synthetic cannabinoids bind more strongly to brain receptors, which is why the effects could be more powerful and unpredictable. Moreover, synthetic cannabinoid products don’t always list every ingredient on the packaging label, so the effects of the product could be greater or different than expected.
Although cannabidiol still requires further study to know all of its health benefits, scientists have been able to pinpoint some of the medical uses of the compound. CBD can help treat nausea and vomiting, making it a useful choice for cancer patients. Cannabidiol may also help shrink the growth of cancer and tumors. It may help people who suffer from psychoses, anxiety and depression. Inflammation and neurodegenerative effects, such as those with Alzheimer’s disease, may be reduced through the use of CBD. Oil made from the compound could even be used to treat forms of epilepsy in children. Its calming effects are also useful for people with social anxiety disorder.
Not gonna lie, I knew that I'd be trying one of these CBD oils on Election Day, and I purposefully saved Medterra since I'd previously used the brand's 3000 mg CBD oil for migraines. I was anxious (I don't think anything could cure election-related anxiety), but I managed to vote in the morning and kept myself feeling relatively positive throughout the entire day. I even went to bed before all of the races were called, which is absolutely unheard of for someone like me. Considering I was a basket case on Election Day in 2016 and ended up crying on my bathroom floor, I was pretty thrilled with how well the Medterra worked.
In addition to the well-known activity on CB1 and CB2 receptors, there is further evidence that CBD also activates 5-HT1A/2A/3A serotonergic and TRPV1–2 vanilloid receptors, antagonizes alpha-1 adrenergic and µ-opioid receptors, inhibits synaptosomal uptake of noradrenaline, dopamine, serotonin and gamma-aminobutyric acid (GABA), and cellular uptake of anandamide, acts on mitochondria Ca2+ stores, blocks low-voltage-activated (T-type) Ca2+ channels, stimulates activity of the inhibitory glycine-receptor, and inhibits activity of fatty amide hydrolase (FAAH) [1, 2].
In addition to acting on the brain, CBD influences many body processes. That’s due to the endocannabinoid system (ECS), which was discovered in the 1990s, after scientists started investigating why pot produces a high. Although much less well-known than the cardiovascular, reproductive, and respiratory systems, the ECS is critical. “The ECS helps us eat, sleep, relax, forget what we don’t need to remember, and protect our bodies from harm,” Marcu says. There are more ECS receptors in the brain than there are for opioids or serotonin, plus others in the intestines, liver, pancreas, ovaries, bone cells, and elsewhere.
