Researchers utilized SPECT neuroimaging with an ECD tracer to assess regional cerebral blood flow of the participants ~90 minutes after CBD or placebo administration. They also administered the VAMS (Visual Analogue Mood Scale) to determine subjective mood of participants throughout the study. After each participant had been examined twice (once with the placebo, once with the CBD) – data was compared.
I work well under pressure, but being extremely busy at work has almost made me less productive—I'm constantly distracted by email, Slack, and the people around me, to the point where getting my work done becomes difficult. This week, however, I've found it easier to put my blinders on, block out all distractions (especially social distractions) and focus on one task at a time. I think this is partly related to the lessened anxiety—I feel more frazzled and off task when my anxiety is running high. It almost feels like a newfound sense of clarity and calm that enables me to focus.
Cannabidiol (CBD) is just one of over 85 scientifically-identified cannabinoids (or chemical compounds) derived from the flowering plant cannabis. Each of the cannabinoids within cannabis elicit unique neurophysiological effects. Most people are well-aware of THC (tetrahydrocannabinol), the predominant cannabinoid within cannabis that is ingested by upwards of 230 million people per year as a psychoactive euphoriant.
While researching for this blog, we discovered some major disparities between the findings in scientific studies and the anecdotal evidence of regular CBD users. Unfortunately, the academic research is fundamentally flawed, and in some cases, seemingly compromised by a conflict of interest. Similarly, it can be difficult to conclude the true nature of anecdotal arguments.

Hey Frank. Indeed there is some exciting research on the effect of CBD on serotonin related receptors. I completely understand why you want to know the ideal dose to take for this purpose. However, it’s not possible for me to provide dosing recommendations. Most people start off by taking the serving size listed on the CBD product they are using. From there, they either decrease or gradually increase the dose as needed. I know that’s not a specific answer but I hope it helps a little. Let me know how I can be of more help and I will do my best 🙂
There were distinct changes in neural activation associated with the significant anxiolytic effects provided by CBD. When compared to the placebo, administration of CBD significantly: increased ECD tracer uptake in the right posterior cingulate gyrus and decreased ECD tracer uptake in the left parahippocampal gyrus, hippocampus, and inferior temporal gyrus. Researchers concluded that reductions in social anxiety from CBD are related to modulation of neural activity in the limbic and paralimbic regions.
Cannabis sativa, a species of the Cannabis genus of flowering plants, is one of the most frequently used illicit recreational substances in Western culture. The 2 major phyto- cannabinoid constituents with central nervous system activity are THC, responsible for the euphoric and mind-altering effects, and CBD, which lacks these psychoactive effects. Preclinical and clinical studies show CBD possesses a wide range of therapeutic properties, including antipsychotic, analgesic, neuroprotective, anticonvulsant, antiemetic, antioxidant, anti-inflammatory, antiarthritic, and antineoplastic properties (see [11, 12, 16–19] for reviews). A review of potential side effects in humans found that CBD was well tolerated across a wide dose range, up to 1500 mg/day (orally), with no reported psychomotor slowing, negative mood effects, or vital sign abnormalities noted .
Despite this, it's important to know that inflammation is not inherently bad; in fact, it's a brilliant aspect of our immune system. When balanced, inflammation heals wounds and fights off infections. The problem with inflammation arises when it increases and never calms down. Like a forest fire burning on in perpetuity, people get hurt. Same goes with the fiery squall of insidious, chronic inflammation. As a natural anti-inflammatory, CBD can help quell the flame and fight chronic inflammation.
The dosages mentioned do not take into account the strength of the tincture. I have Elixinol 300, I took 1/2 dropper (0.5ml, which offers 5mg of CBD) as indicated on the bottle and felt severely nauseous for 3 hours thereafter. There is no way I cold take this dose twice per day, as recommended on the bottle. The high dosages on this site must surely be for much weaker concentrations?
Both Bonn-Miller and Ward stress that it's up to the consumer to be well-educated about the material they're purchasing and the research that's out there. "The companies that are creating [cannabis oils] are offering lots of claims about its use that are not necessarily substantiated by any research," Bonn-Miller said. So "I think there needs to be, from a consumer standpoint, a lot of vigilance," he added.
Even without changes at the federal level, there are steps that states could take on their own to make the CBD market safer. States with broad marijuana legality or CBD-only measures could mandate the calibration and regulation of testing labs, and use them to conduct safety testing. They could fund research into the benefits, dosing, and drug interactions of CBD through their public university systems. Medical boards could redouble efforts to educate physicians in what research exists regarding medical marijuana in all its incarnations, so that doctors are prepared to prescribe and manage these medications as they become available.
Concerned about Mykayla’s stomach cramps, Krenzler, who lives in Portland, Oregon, sent a sample of the oil off to Going Green Labs in Albany, Oregon. Like most labs catering to the cannabis industry, Going Green mainly performs THC potency tests. According to Krenzler, when the lab tested his sample, it found that the Real Scientific Hemp Oil contained much more THC than HempMedsPx had claimed—3.8 percent, instead of roughly 1 percent. Krenzler said he was “disturbed” by the finding, and also by the implications it had for other parents of sick children. Medical marijuana is legal in Oregon, but Krenzler noted that in other states that have not legalized pot, anyone purchasing a product with more than a trace amount of THC could find themselves in legal jeopardy. “I feel that HempMeds had misrepresented their product,” Krenzler said.
Rich in CBD, cannabis has been used for centuries to fight illness, improve sleep, and lower anxiety. Today, our understanding of the potential benefits of CBD is growing by leaps and bounds—more and more, CBD is seen as a powerful disease-fighting agent. Thanks to decades of scientific investigation, it’s now possible to get the benefits of CBD in supplement form.
Responsiveness to certain dosages may be subject to individual variation based on factors such as: body size, whether you take other medications, liver health, etc. For this reason, it is necessary to always review the safety and efficacy of a hypothesized dosage with a medical professional. Also understand that CBD is not guaranteed to reduce anxiety for every user, and therefore some individuals may derive zero benefit from any dose (even if extremely high).
And the products on the shelf aren't all the same, Ward said. "There can be many, many different varieties, and if you're thinking about doing this for medical reasons, you want to find a trusted source and do your research," she said. "Where does that oil come from, and how confident can you be that you know the exact percentages of the different cannabinoids in the product?"
