CBD is well tolerated in humans with doses up to 600 mg not resulting in psychotic symptoms (15). In the few small placebo-controlled studies performed, no significant CNS effects were noted. Oral CBD undergoes extensive first-pass metabolism via CYP3A4, with a bioavailability of 6%. Following single doses in humans, the half-life of CBD when taken orally is about 1 to 2 days.1 In vitro studies have shown that CBD is a potent inhibitor of multiple CYP isozymes, including CYP 2C and CYP3A (16, 17). Whether these in vitro observations are relevant at plasma concentrations likely to be seen in patients is unclear. In addition, given its metabolism via CYP3A4, clinical trials of CBD in patients receiving enzyme-inducing AEDs, such as carbamazepine or phenytoin, will require detailed pharmacokinetic studies.

Most products labeled "hemp oil" do not contain any CBD. Those are typically hemp seed oil which is more commonly used for cooking or to make salad dressing. If you want to buy CBD oil, you'll want to look for products that are labeled "CBD oil" or "hemp extract." To confirm that a product you're interested in has CBD in it, you'll want to look at their third-party lab reports. All reputable companies selling CBD oil products will make third-party lab reports available to you to confirm the presence of CBD.


Cannabidiol pharmacological effects are mediated through G protein coupled receptors, cannabinoid type I (CB1) and cannabinoid type II (CB2), which are highly expressed in the hippocampus and other parts of the central nervous system (2). When activated, CB1 receptors inhibit synaptic transmission through action on voltage-gated calcium and potassium channels, which are known to modulate epileptiform and seizure activity (3). CB2 receptors are primarily expressed in the immune system and have limited expression in the central nervous system. The effects of CBD are CB2 receptor independent (3).

A survey of patients seen in a tertiary epilepsy center found that 21% of patients admitted to using marijuana in the last year, and 24% of patients believed marijuana to be effective for their seizures (10). While interesting, this anecdotal observation does not rise to the level of evidence needed to evaluate a potential new therapeutic modality.
Though hemp oil is a different classification of product than CBD oil, many health benefits have been reported by amazon consumers on a consistent basis. Abundant vitamin E, Omega-3 and Omega-6 content in hemp seed oil can assist in a variety of health issues. Hemp oil is a natural, environmentally friendly, and healthy alternative to common health supplements containing Omega-3 and Omega-6, such as fish oil. In the management of pain, anxiety, and other serious health-related symptoms, the intensity of CBD and hemp oil’s effects tend to vary by person, despite the manufacturer and quality of product. However, the vast majority of consumers indicate very positive and even calming effects following hemp oil use. In choosing the best amazon product for quality and optimal benefits, it’s important to remember that only full spectrum hemp oil derived from the entire hemp plant contains the CBD cannabinoid. Whether used as a daily addition to any health regimen or used to help manage symptoms brought on by major health problems, CBD and hemp oil can carry significant benefits. In the end, it never hurts to explore how they may benefit your health, especially when you know everything about the product you’re receiving! Written by the team at CBD Education Online

CBD can be expensive, especially if you’re buying good organic products that are properly tested. If a brand is spending tens (even hundreds) of thousands of dollars a year on true organic farming and state-of-the-art quality testing to ensure a great product, paying a premium is worth it. If a brand is charging a lot simply to capitalize on the hype, that’s a problem. We put together a list of the best value CBD oils we found when researching brands.
Do I want a brand that does one thing great or has everything I need? Consider product diversity. Some people like to shop brands who have a very narrow expertise. Other people like access to capsules, vapes, gummies, and suppositories all in one place. The main thing to look out for is white labeling. Is the company who sells everything accountable for the manufacturing of those products or are they a storefront?

CBD stands for cannabidiol. It is the second most prevalent of the active ingredients of cannabis (marijuana). While CBD is an essential component of medical marijuana, it is derived directly from the hemp plant, which is a cousin of the marijuana plant. While CBD is a component of marijuana (one of hundreds), by itself it does not cause a “high.” According to a report from the World Health Organization, “In humans, CBD exhibits no effects indicative of any abuse or dependence potential…. To date, there is no evidence of public health related problems associated with the use of pure CBD.”
Amazon reviews may be few, but each are 5-star and outline excellent experiences in the management of pain and stress. On the company’s website, a plethora of customers site amazing experiences in managing pain. Consumers of Panacea’s F.A.S.T. hemp oil tablets are assisted in chronic pain and symptoms of anxiety, and mention assistance with sleeplessness and opioid use as well. All in all, buyers on amazon have experienced excellent satisfaction in results following regular use.
Other targets for CBD include transient receptor potential (TRP) channels that are involved with the modulation of intracellular calcium (1, 6). Cannabinoids are highly lipophilic, allowing access to intracellular sites of action, resulting in increases in calcium in a variety of cell types including hippocampal neurons. CBD actions on calcium homeostasis may provide a basis for CBD neuroprotective properties.

Thank you for the information.  A friend of mine recently gave me a small bottle of Cloud 9 hemp, lizard king.  Said she was told it is good for COPD.  Can not find anything that backs up that statement, You article also said that Cloud 9 is a brand that uses Propylene and the effects on the lungs when vaporizing has not been determined but OK to use externally.  Is all this correct?

Now that CBD has become so popular, growers are creating strains of the cannabis plant that are optimized for producing high amounts of this particular cannabinoid. There are tons of new strains on the market that feature a high CBD-to-THC ratio. This makes it even easier for the processing facilities to remove the CBD and turn it into an oil extract.
That being said, if you type "cbd oil" on Amazon in its search box, you will get search results that appear to be CBD oil. This understandably confuses people looking to buy CBD oil online. The reality is that most of those products are just hemp seed oil that don't contain any CBD. There is definitely a difference between hemp oil and CBD oil as explained in the article "What's The Difference Between Hemp Oil and CBD Oil?"

I have stage 4 kidney disease and struggle with congestive heart disease. My friend offered me some CBD oil and I decided what the hell, I’m 52 and dying. I stopped smoking using a JUUL vaper. I now refill my pods myself with 18% ECBlend Caranilla juice made locally in Oregon. I mix 10 drops of CBD to my refill of the Caranilla juice. I’ll keep you informed on what effects my blood tests show as I pray the oil helps pull up my renal functions.
The science behind CBD is in the relatively early stages. As a cannabinoid, we know that CBD interacts with receptors in your endocannabinoid system. The endocannabinoid system is integrated throughout your body — and this widespread, whole-body interaction creates a broad range of effects. Hence, the long list of possible benefits.   We may still be in the early stages of discovery, but there’s plenty of scientific studies and anecdotal evidence that CBD provides relief for an array of ailments. Here’s a non-exhaustive list of some potential benefits of CBD oil:
However, like we just mentioned CBD oil for pain management that has been sourced from industrial hemp grown under the farm bill is in fact legal to buy and sell. The best CBD oil brands that we cover here on this site, claim to extract their concentrates from U.S.-based industrial hemp supplies, which if true, are 100% legal since they contain negligible amounts of THC.
However, switching to CBD oil from a conventional medication is far from a random stab in the dark. In fact, there was a large scale (and very well-documented) survey carried out less than two years ago that looked at precisely what percentage of patients were able to “swap” their side effect-inducing meds for a 100% natural, cannabis-based therapy.

Born in Brooklyn, New York, Dave has always had a passion for helping people quit smoking. As a former smoker himself, he knew how hard it could be. As soon as he learned about vaping, he instantly became obsessed with it and helped many people stop smoking. Vaping360 has given Dave a platform to do this on a much larger scale, by educating the public about the wonders of vaping. When Dave is not writing he is either listening to music, performing it, or cruising around on his Penny board.

These reports suffered from a number of design flaws, including incomplete baseline quantification of baseline seizure frequency, indeterminate time periods for outcome determination and, in some cases, inadequate (or missing) statistical analysis—in general, a lack of sufficient detail to adequately evaluate and interpret the findings. Limitations aside, several studies did report that administration of adjunctive CBD did not result in meaningful changes in seizure frequency (11–13).
