Speaking of dosage, in most clinical trials, you’ll see CBD dosing ranges from 10-800 mg of CBD per day (although to treat schizophrenia, I’ve seen doses as high as 1,300mg). But as with everything from whey protein to creatine to magnesium, everyone is different and you’ll likely need to experiment with a dosage range that works for you. The CBD capsules I personally use contain 10mg in one capsule, but based on the absorption (an important variable which you’re going to learn about next), I need to use far less CBD, about 1/10 the amount, compared to other CBD tinctures, extracts and capsules I’ve tried.
In addition to fighting inflammation in the body, CBD oil may reduce anxiety by directly affecting the brain. Studies have found that CBD actually lowers activity in the amygdala and increases prefrontal cortex activation, two parts of the brain involved in anxiety. There is also evidence that CBD is able to activate hippocampus neurogenesis, aka regenerate new neurons! This activates CB1 receptors, which has a positive balancing impact on GABA and glutamate levels, associated with reducing anxiety.
Extraction: The method by which CBD oil is processed from hemp plants can be very telling. Some manufacturers extract and process the oil using toxic materials like propane or butane; in most cases, these oils are cheaply priced. Safer extraction and processing agents include ethanol, which cleans the hemp plant of unwanted toxins; and supercritical carbon dioxide extraction, which strips harmful materials from the plant by changing the carbon dioxide’s temperature and pressure settings.
Leonard Leinow has three decades of experience growing and studying medical cannabis and brings a unique spiritual perspective to his work. In 2009, he formed Synergy Wellness, a not-for-profit medical cannabis collective in California. Synergy Wellness has over 3,500 members in its collective and is an artisan organization making hand-crafted organic and natural whole plant-based products. They are specialists in CBD (cannabidiol), the non-psychoactive portion of cannabis, and are pioneers in this aspect of the industry. Leinow is known for his proprietary blends of tinctures and medicine used for cancer and epilepsy patients.
Full spectrum CBD does, however, bring with it the sticky issue of THC. The government regulates concentration levels of THC at 0.3 percent, an amount which results in minimal psychoactivity. But THC metabolites are stored in the fat cells of your body, building up over time. If you ever need to take a drug test, this could create an issue for you.
Relevant studies are summarized in Table Table2.2. The anxiolytic effects of CBD in humans were first demonstrated in the context of reversing the anxiogenic effects of THC. CBD reduced THC-induced anxiety when administered simultaneously with this agent, but had no effect on baseline anxiety when administered alone [99, 100]. Further studies using higher doses supported a lack of anxiolytic effects at baseline [101, 107]. By contrast, CBD potently reduces experimentally induced anxiety or fear. CBD reduced anxiety associated with a simulated public speaking test in healthy subjects, and in subjects with SAD, showing a comparable efficacy to ipsapirone (a 5-HT1AR agonist) or diazepam [98, 105]. CBD also reduced the presumed anticipatory anxiety associated with undergoing a single-photon emission computed tomography (SPECT) imaging procedure, in both healthy and SAD subjects [102, 104]. Finally, CBD enhanced extinction of fear memories in healthy volunteers: specifically, inhaled CBD administered prior to or after extinction training in a contextual fear conditioning paradigm led to a trend-level enhancement in the reduction of skin conductance response during reinstatement, and a significant reduction in expectancy (of shock) ratings during reinstatement .
Still, as the saying goes, absence of evidence isn’t necessarily evidence of absence, and there’s a reason we don’t have a ton of solid research on CBDs yet — “to study it, we need a good source, ” said Ziva Cooper, who is an associate professor at Columbia University and was on the National Academies committee. CBD is hard to get because it’s still technically a Schedule I drug, which limits its availability, Cooper said.
A 2012 research review assessed a number of international studies and concluded that CBD has been shown to reduce anxiety, and in particular social anxiety, in multiple studies and called for more clinical trials. Two years later, researchers in an animal study related to stress and the endocannabinoid system wrote that augmentation of the endocannabinoid system might be an effective strategy to mitigate behavioral and physical consequences of stress.
Would I say that CBD oil has fundamentally changed my life? No. But per the Charlotte's Web website, this is the typical first experience. "Anyone who has ever started a new vitamin or supplement routine knows the short answer to how long it takes to kick in is—'it depends,'" reads the article on what to expect from hemp oil. "For many newcomers, they're not sure what to imagine, or some anticipate a huge change right away. For most of us, though, dietary supplements take time."
