While experts — including Cargile, Romanowski, and Carqueville — note that there hasn’t been a ton of research done on the potential risks of CBD oil, it’s thought to be a pretty low-risk product. “First of all, using anything topically reduces the risks right off the bat,” Cargile says. “There’s not a lot of research, however CBD and THC, cannabis and hemp have been used for thousands of years. And according to the Centers for Disease Control [and Prevention], which reports deaths in this nation, [marijuana] causes zero deaths every year so it’s found to be very safe.”
@parus i just got my certification for medical marijuana. Upon buying what was recommended I was given CBD oil, I’ve not been on it a week yet today will be my fourth day of using it. It takes about 1/2 hour to work but it seems to help. They also gave me a cannabinol patch to use at night fir the severe itch in my head from the shingles. Also a vape two puffs as needed for the itch break through which I have not tried yet. I’m a bit anxious about using it.
CBD concentrates typically contain the strongest dosage of CBD compared to any other CBD products. It can contain up to 10 times the average CBD products. Concentrates are also convenient in that it only takes a few seconds to consume. Overall, CBD concentrates seem to be most popular among customers who are extremely busy, yet seek high potency CBD.

CBD oils may contain some THC. Cannabis may impair your ability to drive safely or operate equipment and may have short- and long-term effects on your memory, attention, mood, heart rate, and mental health. It is also easy to overconsume CBD oil, so it's important to start with a low dose, as it may take several hours or longer to begin to feel the effects after consumption.


At sufficient doses (400-600 mg), CBD can alleviate situational anxiety, such as public speaking. Interestingly, cannabis cultivars, or strains, that are high in CBD and low in THC are better than other cultivars for alleviating depression. But when used over a long period of time, any kind of cannabis could make depression worse.  Although clinical trials in people haven’t yet been completed, there is very compelling “petri dish” evidence that CBD can reduce inflammation, for painful conditions such as Crohn’s disease, and fight some cancerous tumors. There is a massive amount of scientific research being done on CBD right now, and we are likely to see many medical breakthroughs in the next decade.
CBD exerts several actions in the brain that explain why it could be effective in treating anxiety. Before we dive in, it’s important to note that most research describing how CBD works is preclinical and based on animal studies. As the saying goes, “mice are not men” — and, results from animal studies don’t always neatly transfer to human therapies. However, preclinical studies provide insights that move us in the right direction:
Non-selective calcium permeant cation channel involved in osmotic sensitivity and mechanosensitivity. Activation by exposure to hypotonicity within the physiological range exhibits an outward rectification (PubMed:18826956, PubMed:18695040). Also activated by heat, low pH, citrate and phorbol esters (PubMed:18826956, PubMed:18695040). Increase of intracellular Ca(2+) potentiates currents. Channel activity seems to be regulated by a calmodulin-dependent mechanism with a negative feedback mechanism (PubMed:12724311, PubMed:18826956). Promotes cell-cell junction formation in skin keratinocytes and plays an important role in the formation and/or maintenance of functional intercellular barriers (By similarity). Acts as a regulator of intracellular Ca(2+) in synoviocytes (PubMed:19759329). Plays an obligatory role as a molecular component in the nonselective cation channel activation induced by 4-alpha-phorbol 12,13-didecanoate and hypotonic stimulation in synoviocytes and also regulates production of IL-8 (PubMed:19759329). Together with PKD2, forms mechano- and thermosensitive channels in cilium (PubMed:18695040). Negatively regulates expression of PPARGC1A, UCP1, oxidative metabolism and respiration in adipocytes (By similarity). Regulates expression of chemokines and cytokines related to proinflammatory pathway in adipocytes (By similarity). Together with AQP5, controls regulatory volume decrease in salivary epithelial cells (By similarity). Required for normal development and maintenance of bone and cartilage (PubMed:26249260).
The equivalency factor is not designed to compare the effects of cannabis oil to dried cannabis, or provide dosage information. For many patients, consuming cannabis orally will produce much stronger effects than inhaling it. For example, when considering a product that has an equivalency factor of 12ml of oil to 1 gram of dried cannabis, and a patient who usually consumes 1 gram of dried product a day, this patient will likely use less than 12 ml of oil per day. Even for patients who have previous experience of using cannabis oil, it is recommend that you start with a low dose and go slow.
If an athlete happens to get a CBD oil that is very low in THC and other cannabinoids, or if they stop using a product in time to ensure that any THC or other cannabinoids are cleared from their body, then the use of a CBD product will not cause a positive test or cause the athlete to incur an anti-doping rule violation. Unfortunately, it is impossible to know how much THC or other cannabinoids are in a CBD product just from looking at the label, and it is impossible to predict how each athlete will metabolize and excrete THC or other cannabinoids. The use of any CBD product is at the athlete’s own risk.

Hemp oil is also rich in "super" polyunsaturated fatty acids, most notably gamma-linolenic acid and stearidonic acid. Although these are not essential fatty acids, they may help reduce the symptoms of atopic dermatitis and other skin conditions. However, the amount of these non-essential fatty acids varies according to the quality of the hemp plant the acids were derived from.
Hash oils seized in the 1970s had a THC contents ranging from 10 to 30%. The oil available on the U.S. West Coast in 1974 averaged about 15% THC.[2] Samples seized across the United States by the Drug Enforcement Administration over an 18-year period (1980–1997) showed that THC content in hashish and hashish oil averaging 12.9% and 17.4%, respectively, did not show an increase over time.[4] The highest THC concentrations measured were 52.9% in hashish and 47.0% in hash oil.[5] Hash oils in use in the 2010s had THC concentrations as high as 90%[6][7] and other products achieving higher concentrations [8]
If you haven’t been bombarded with CBD marketing or raves about it from friends, get ready. This extract—which comes from either marijuana or its industrial cousin, hemp—is popping up everywhere. There are CBD capsules, tinctures, and liquids for vaping plus CBD-infused lotions, beauty products, snacks, coffee, and even vaginal suppositories. Already some 1,000 brands of CBD products are available in stores—and online in states that don’t have lenient cannabis laws. This is a tiny fraction of what’s to come: The CBD market is poised to exceed $1 billion by 2020, per the Chicago-based research firm Brightfield Group.

Although both oils are generally safe for use, the main difference between hemp oil and marijuana oil comes down to the THC content, which contributes to their different side effects. Marijuana’s THC content naturally contributes to more potential side effects related to memory, learning, and general cognition, which invariably means you shouldn’t be doing anything important, operating heavy machinery, or driving after taking marijuana oil. By comparison, hemp oil has far fewer side effects. Most side effects are related to hemp oil’s high polyunsaturated fat content, which may contribute to heart disease and digestive problems, but only if you are ignoring serving recommendations.


Anxiety disorders are the most common mental health concern in the United States. An estimated 30 percent of adults in the United States (that's 66 million people) and an estimated 25 percent of teenagers and preteens are affected by anxiety. As a functional medicine practitioner, I see many people who struggle with anxiety and panic attacks, and from these statistics, it should be no surprise. But just because something is common doesn't make it normal. Fortunately, new insights into the cause of anxiety may help with the development of more effective treatment options.
AC/DC: A Sativa-dominant phenotype of Cannatonic, this cultivar boasts one of the highest ratios of CBD to THC, clocking in at 20:1. AC/DC is claimed to help reduce pain, anxiety, depression and migraines while reducing symptoms in patients with epilepsy, some forms of cancer, and multiple sclerosis. This cultivar’s pinene-rich terpene profile offers potent clear-headed pain relief.
Receptra Naturals CBD products are derived from proprietary CBD rich hemp, grown on family owned and operated farms in Colorado using 100% organic farming practices on select organic soils without the use of pesticides or fungicides.  I got to know the folks at Receptra while dealing with Charlotte's Web Botanicals years back and continued to stay in contact when they left CW to form Receptra Naturals. 
Thank you for reaching out to us. You could most definitely try our premium hemp oil drops or soft gels. Our premium hemp oil products are great for assisting with a lot of different things such as pain, inflammation, stress, anxiety, mood and sleep. I would start out with our 3x strength option that we have available, and the best method is the drops. You take the recommended amount of drops listed on the bottle, under your tongue. You let the drops sit there for 30 seconds. After the 30 seconds, you swallow the remaining oil in your mouth. Buy doing so this will enter your bloodstream to deliver faster results. Although, I would recommend talking to a doctor before going off any prescribed medicine.

As the PeaceHealth website suggests, hemp oil derives from a plant that contains high levels of the neurological chemical THC. This chemical can cause hallucinations, euphoria or high anxiety in supplement users when taken on a regular basis. As such, hemp oil supplements can cause similar effects in some patients using the herb for the treatment of any disorder. It is recommended that supplement users not take hemp oil products prior to operating machinery or driving due to the risk of these hallucinogenic properties. This is especially true to individuals who are overly-sensitive to THC, which can be determined by visiting your medical doctor for more information.
FDA is not aware of any evidence that would call into question its current conclusions that THC and CBD products are excluded from the dietary supplement definition under sections 201(ff)(3)(B)(i) and (ii) of the FD&C Act. Interested parties may present the agency with any evidence that they think has bearing on this issue.  Our continuing review of information that has been submitted thus far has not called our conclusions into question.

Hemp oil is a great source of high-quality nutrients and has a long history of use in Eastern culture as a multi-purpose natural remedy. Despite its widespread popularity, prejudice related to its association with Marijuana it has kept it from common use in the West. While Hemp oil contains virtually no THC (the psychoactive element in cannabis) hemp oil is still concerning to some. Thankfully, education is prevailing and the market for hemp oil is growing in the United States, with an increasing number of people seeking it out for its reported health benefits.
Hempseed oil is manufactured from varieties of Cannabis sativa that do not contain significant amounts of tetrahydrocannabinol (THC), the psychoactive element present in the cannabis plant. This manufacturing process typically includes cleaning the seed to 99.99% before pressing the oil. There is no THC within the hempseed, although trace amounts of THC may be found in hempseed oil when plant matter adheres to the seed surface during manufacturing. The modern production of hempseed oil, particularly in Canada, has successfully lowered THC values since 1998.[5] Regular accredited sampling of THC in Canadian hemp seed oil shows THC levels usually below detection limit of 4 ppm (parts per million, or 4 mg/kg). Legal limit for THC content in foodstuffs in Canada is 10 ppm.[6] Some European countries have limits of 5 ppm or none-detected, some EU countries do not have such limits at all.
Therefore, ingesting 2,000 mg of CBD oil daily would result in a maximum consumption of 6 mg of THC, which would cause a positive marijuana urine test approximately 23 percent of the time. It’s important to keep in mind the amount of CBD consumed. Although unlikely, it is possible for those who take CBD to fail drug tests if they are taking unusually high doses.
Based on client feedback, as well as our own R&D, we have chosen to use Grape Seed Oil, which has a very high content of polyunsaturated fats, and is rich in Omega 3-6 as well as Omega-9 essential fatty acids. Grape Seed Oil is NOT recognized as an allergen by Health Canada (HC) or the Canadian Food Inspection Agency (CFIA); however, some people may have sensitivities to it.
Been using product for a few days now ,I'm about one my 6th dose. I noticed today my hand from nerve damage has not dropped anything or felt numb,or even trembled. Even axienty has been managable. However I'm taking 250mgs.I boosted it up to 500mgs.3 or 4 times daily ,of 250mgs. It seems to have best effect atleast today.It's cold and rainy which,is better than snow ,is my most hightened pain days.Today 4/24/18. Has been a God send! 1 pain and axienty day free ...Makes me a believer! I stand by this products effectiveness. Hope my review helps another soul,that lives with same aliments.
Cutting-edge science has shown that the endocannabinoid system is dysregulated in nearly all pathological conditions. Thus, it stands to reason that “modulating endocannabinoid system activity may have therapeutic potential in almost all diseases affecting humans,” as Pal Pacher and George Kunos, scientists with the U.S. National Institutes of Health (NIH), suggested in a 2014 publication.
There are likely very complex relationships also occurring between various Cannabinoids in Cannabis that may lead to certain medical efficacy. That is important to remember when considering the consumption of products that contain Cannabinoids. There is an attractiveness to isolating a specific chemical, researching it, patenting synthetic derivatives, and marketing specific drugs. That said, the relationships are complex, will likely take years to understand, and many patients I’ve met appear to find the most medical benefit from a diverse group of Cannabinoids whose interactions are not particularly well understand, but the results are hard to argue with.
Due to its high content of omega 3 and omega 6 fatty acids, hemp oil has a composition similar to skin lipids, which makes it an excellent natural emollient and moisturizer. It is especially useful for dry, tired or dehydrated skin and nails. It increases the skin elasticity and water retention capacity in tissues. Pure hemp oil can be used to treat dry hair and is often included in hair conditioners.
The hard truth about most anxiety disorders is that they make you bummed out, even in your downtime. Especially in your downtime. CBD, when combined with THC, has antidepressant properties, which regulate your emotional response and your general way of thinking. There are two ways for that to happen: When ingested, CBD activates 5-HT1A receptors. By doing so, it enables the brain to send more serotonin signals, thus reducing the anxiety and boosting your general mood.
FDA is not aware of any evidence that would call into question its current conclusions that THC and CBD products are excluded from the dietary supplement definition under sections 201(ff)(3)(B)(i) and (ii) of the FD&C Act.

Cannabidiol (CBD) is a subclass of Phytocannabinoids and one among one twenty cannabis compounds. It is hailed for its ability to be meditative, without causing a euphoric high. This non-addictive miracle cannabinoid has been the talk of the town and the core of numerous experiments. The anti-inflammatory properties of CBD have inspired the marketing of its by-products, such as CBD oil, for pain relief and relaxation.
Here, the evidence is not going to make them happy. A 2017 study in JAMA reported that only 26 of 84 samples of CBD oils, tinctures and liquids purchased online contained the amount of CBD claimed on their labels. Eighteen of them contained THC, which could lead to intoxication or impairment in some individuals. And a quarter had less CBD than advertised. The F.D.A. has likewise found many products that did not contain the amount of CBD they were claiming.
All CBD tinctures are not mamade equally. They come from hemp strains that have varying amounts of terpenes…some beneficial to anxiety, others not as much. Depending on how the oil was processed and what phytochemical profile it had to begin with, will impact its affect on you. Start with full-spectrum always but then look for beta-c & other anti-anxiety compounds in the product formulation
Δ9-THC is also responsible for the pharmacological effects of cannabis, including its psychoactive properties, although other contents of the cannabis plant also contribute to this effect. In particular, CBD, a non-psychoactive phytocannabinoid common in some cannabis strains, has anti-inflammatory, analgesic, anxiolytic and antipsychotic properties.
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].
