Unlike THC, CBD will not make you high. That said, this doesn’t mean CBD is not at all psychoactive, as many assert, says Jahan Marcu, PhD, director of experimental pharmacology and behavior at the International Research Center on Cannabis and Mental Health in New York City: “CBD does change cognition. It affects mood, which is why people take it for anxiety. And some find that it makes them more alert.”

It’s safe to say that Charlotte’s Web is probably the most recognized CBD brand out there — and it’s not all hype. This company pioneered the CBD industry and made it their mission to de-stigmatize CBD by setting the bar high for transparency. They produce and oversee their organic CBD products from seed to sale, standing behind them with a solid return policy. 
After consulting with Amanda Chantal Bacon of Moon Juice, I decided to invest in a bottle of Gone Green Hemp CBD Oil in the 500mg tincture. Gone Green is a really incredible company that only sources the best herbs, adaptogens, and superfoods, so I knew I would be getting a very high-quality product when I grabbed their bottle off of Moon Juice’s shelf. You can buy Gone Green’s Hemp CBD Oil online—it’s 100% legal in all 50 states. They have the best customer service ever, and they carry tons of other fantastic products that any health-conscious person would love!
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.
Although it is great that you have compiled a long list of the best CBD oils, so that we get some choice also as consumers, however, I rely believe in your well researched information that you share always, and so I feel the number 1. you shared, Purekana is going to make the choice for me. Ordering it tonight, and let’s see how my CBD journey goes from here. A bit nervous though!
And then I woke up on the concrete, a worried crowd gathered around me. “You had a seizure,” my friend said gently as I blinked my eyes, trying to process this new information. I remember it was warm that night because I was wearing a sundress, and when I finally regained consciousness my first worry was that my dress flew up and everyone could see my underwear.

I recently was a guest at a medical marijuana educational event that highlighted the work of researcher Michael Backes. During his presentation he made a statement about CBD that I have never heard anywhere else that CBD is “regulating” (my word) the effects of THC. I asked the Nurse Practitioner at the event, Ivy Lou Hibbitt of Certicann.com, what he meant by that and she said it was her understanding of Michael’s comment that he takes CBD to reduce the psychoactive effects of THC. Has this property of CBD, that it can lessen psychoactive effects, ever been researched elsewhere?
Although CBD oils aren’t regulated by the FDA, purchasing products stateside from one of the nine states where recreational and medical cannabis use is legal will likely result in a higher-quality product than buying one made with hemp-derived CBD oil imported from abroad, says Martin Lee, director of Project CBD, a nonprofit that promotes medical research into CBD.
Our hemp oil tinctures offer the most accessible means to getting started with CBD hemp oil supplements. Registering our lowest price point among our products, our 1 oz tinctures contain the lowest concentration of CBD in our products. With around 1 mg of CBD per serving, our 1 oz tinctures are good for those looking to integrate the smallest amount of CBD into their daily routine. The tinctures in the 2 oz bottle add 2.5 times the potency, for a total of 500 mg per 2 oz bottle.
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.
Since it started becoming popular roughly two years or so ago, the general consensus has always been that since CBD oil from top brands does not contain the psychoactive properties of THC, it is therefore legal. Unfortunately, its legality is much more nuanced because of conflicting federal laws and new court cases. What is clear is that in one of the most recent court decisions on the topic, Hemp Industries Assoc. v. DEA, which came out on April 30, 2018, the US Court of Appeals for the Ninth Circuit found that Section 7606 of the 2014 US Farm Bill (the “Farm Bill”) preempts the Controlled Substances Act (CSA), the federal law which designates marijuana as a Schedule I substance (along with heroin and cocaine) making it illegal to possess or use. This means that when there is conflict between the CSA and the Farm Bill, the Farm Bill wins out.
If your intention is to help treat chronic pain, then you may want to start out with a lower dose, and then proceed from there. If you notice effective results, you can downsize the dose, or likewise you can always up the dose until positive results are achieved. The key is to only increase your dosage in small increments so that you are able to pinpoint exactly how much CBD oil it takes to treat your condition. Be advised, though, that you should not exceed the recommended daily doses that are listed on the bottle and you should consult with a physician.

The endocannabinoid system is spread throughout your brain and body, but primarily throughout your central nervous system. The interaction between cannabinoids and receptors is what produces effects like the regulation of mood, pain, appetite, inflammation, and memory. Plant-based cannabinoids, found in cannabis plants, also interact with the receptors (whimsically named CB1 and CB2) in the endocannabinoid system, and each affects your body in different ways. CBD and its infamous cousin THC are the 2 most well-known cannabinoids.

Transparency: Receptra Naturals’ website has a database where you can look up lab reports for their products. The first time we checked, we got some 404 errors for a couple of the lab reports, but these glitches seem to have been fixed since then. We were able to see third-party lab reports for all their tinctures (though, apparently not for their topicals). 

It makes no sense to me that something that helps with anxiety has an irritability side effect – as a lot of my anxiety is co-mingled naturally with irritability. Further, I have noticed none of these side effects, given that if you become fatigued or sleepy, you adjust dose the next day. So I don’t call that a side effect – rather – an effect of taking too much.


Like we said, once you start using CBD oil more frequently and are able to gauge how much you need to find relief or therapy, then you can jump up to the more high-potency products as needed. For reference, doses will typically range anywhere from 5 mg to 100+ mg in a single day. And for epilepsy patients, they may take anywhere between 300 mg to an entire gram (1,000 mg) per dose — or more!

Social media is blasting this one out lately, showing that different parents have been treating their children illegally (in states that are not classed as medical states) to help prevent their children from having seizures or deal with epilepsy. While there has been limited scientific evidence on the topic, 2016 was a major turning point for the plant as a major study was conducted by Orrin Devinsky, a neurologist at New York University Langone Medical Center, showing profound results.


Consume CBD oil if you want to quit smoking cigarettes. While consuming CBD oil, people sometimes report craving nicotine less. Withdrawal symptoms like anxiety and mood swings also aren’t as severe for many people when they take CBD oil. If you’re struggling to quit smoking cigarettes, try using CBD oil to potentially diminish your cravings and withdrawal symptoms.[13]


The amount of milligrams of CBD you should take depends on your specific reason for taking CBD. If you are using CBD to treat chronic pain, you might take a much higher dose than someone who would be using CBD for general wellness reasons. Google search for your specific condition or reason for taking CBD to find the dose that is appropriate for you. You can take CBD in high qualities, so feel free to test out different dosages and see how your body reacts. A standard dose of CBD is 10 mg once a day, but this varies so widely because each individual is different so this can’t be taken as a recommendation for you.
