Laboratory evidence indicated that cannabidiol may reduce THC clearance, increasing plasma concentrations which may raise THC availability to receptors and enhance its effect in a dose-dependent manner.[25][26] In vitro, cannabidiol inhibited receptors affecting the activity of voltage-dependent sodium and potassium channels, which may affect neural activity.[27] A small clinical trial reported that CBD partially inhibited the CYP2C-catalyzed hydroxylation of THC to 11-OH-THC.[28]
It depends on the dose and the person. Dr. Bonni Goldstein, M.D., the medical director of Canna-Centers, notes that it’s hard to figure out how exactly CBD will affect individuals. “It’s unclear at this point in time the exact interaction between CBD and caffeine,” she says. “At low doses, CBD is a stimulant and in higher doses it can cause sedation....Someone’s reaction to a combination of these compounds would not be easily predictable because various doses of each would affect the response,” Goldstein explains.
“CBD inhibits the cytochrome P450 enzymes that break down important psychiatric drugs,” says Blessing. CBD isn’t the only substance that messes with the body’s ability to metabolize these drugs — both St. John’s wort and the humble grapefruit are unfriendly — but CBD is comparatively poorly studied. The way CBD inhibits those enzymes could dramatically raise the levels of SSRIs or opioids in the system, potentially leading to an overdose.
In the meantime, some physicians are forging ahead — and cashing in. Joe Cohen is a doctor at Holos Health, a medical marijuana clinic in Boulder. I asked him what CBD is good for, and he read me a long list of conditions: pain, inflammation, nausea, vomiting, intestinal cramping, anxiety, psychosis, muscle spasms, hyperactive immune systems, nervous system degeneration, elevated blood sugar and more. He also claimed that CBD has anti-cancer properties and can regenerate brain cells and reduce the brain’s levels of amyloid beta — a kind of protein that’s been linked to Alzheimer’s disease. I asked for references, noting that most of these weren’t listed in the Academies report or a similar review published in the Journal of the American Medical Association. “I think you just have to Google search it,” he said. It’s true that a preliminary study found hints that cannabinoids might reduce beta amyloid proteins in human brain cells, but the study was done in cells grown in a lab, not in people. As for cancer, the FDA sent warning letters last year to four companies that were selling products that claimed to “prevent, diagnose, treat or cure” cancer.
They may be safe, but there's one massive problem: There's practically no scientific data to support the idea that a CBD-infused topical cream is any more effective than other topical pain relievers, like Tiger Balm, BenGay, or Icy Hot. Michelle Sexton, a San Diego-based naturopathic doctor and medical research director of the Center for the Study of Cannabis and Social Policy says that her patients do seem to have a great interest in CBD ointments, and roughly 40 percent of them have indeed tried one. However, these people are in her office now because the topicals didn’t work for them. "As a medical professional, my opinion is there’s little evidence to back up the claims being made—it’s all marketing for now," she says.
Hi Bev, I am curious my husband has the exact same issues, and then ends up picking his poor head like crazy which aggravates the scalp sores. We figured out that he has extremely thick hair and the follicles are too densely packed together and his scalp cannot breathe. Since we figured that out he has been going in for hair cuts where they thin his hair out a lot as well as cut it so his scalp can breathe….. Overall he is doing much better as long as we stay on top of the hair trims and thinning cuts but if he doesn’t go in regularly he is back to the irritation. BTW topical MMJ is great but they can be very oily and have compound stuff in them that can further irritate the scalp possibly etc. so maybe not great for scalp… 🙂 I have traumatic injuries from a car accident and the MMJ topical creams have saved my life…..
CBD products have become increasingly popular in recent years, as more and more producers market CBD as the new "it" drug for the health and wellness set — one that has been touted as a pain reliever and a treatment for anxiety, among other potential applications. Last year, consumer sales of CBD products topped $350 million in the United states, more than triple the amount sold in 2014, and various estimates predict the market could reach $2 billion within the next two to four years.
In just a few years, cannabidiol (CBD) has become immensely popular around the world. After initially being discovered as an effective self-medication for Dravet syndrome in children, CBD is now sold and used to treat a wide range of medical conditions and lifestyle diseases. The cannabinoid CBD, a non-psychoactive isomer of the more infamous tetrahydrocannabinol (THC), is available in a growing number of administration modes, but the most commonly known is CBD oil. There are currently dozens, if not hundreds, of producers and sellers of CBD oils active in the market, and their number is increasing rapidly. Those involved vary from individuals who prepare oils on a small scale for family and (Facebook) friends to compounding pharmacies, pharmaceutical companies, and licensed cannabis producers. Despite the growing availability of CBD, many uncertainties remain about the legality, quality, and safety of this new “miracle cure.” As a result, CBD is under scrutiny on many levels, ranging from national health organizations and agricultural lobbyists to the WHO and FDA. The central question is whether CBD is simply a food supplement, an investigational new medicine, or even a narcotic. This overview paper looks into the known risks and issues related to the composition of CBD products, and makes recommendations for better regulatory control based on accurate labeling and more scientifically supported health claims. The intention of this paper is to create a better understanding of the benefits versus the risks of the current way CBD products are produced, used, and advertised.
A quality CBD topical cream provides the advantage of being able to apply the active therapeutic hemp extract directly to the site of aggravation or discomfort. This is particularly useful for application to joint areas or superficial muscle tissue, as the cannabidiol compound will diffuse across the dermal layers directly to the site of pain and inflammation.
That said, both Blessing and Carson warn that CBD should still be considered a drug, which means it can interact with other drugs. “CBD does interact with drugs that people are taking,” says Blessing. “So if you’re taking an opioid cough suppressant, or you’re taking serotonin-based medicine, like an SSRI, you can have strong drug interactions.” While most coffee shops are likely using doses too low to cause such interactions, Blessing says it’s something to be aware of. “If a coffee shop happened to have a way of making a product with a lot of CBD in it, then that could really interact with the medication this person is taking, and the effects they think are due to CBD could partly be due to that medication interaction,” she says.
In fact, the law is pretty unclear when it comes to CBD’s state-by-state legality and people (mostly people of color, because a hard-to-interpret law is ripe for racist mishandling) are occasionally charged with possession for carrying CBD. There is a bill in the works (spearheaded by Senator Mitch McConnell, no less) that seeks to get rid of hemp restrictions federally, which would make at least one facet of the law easier to interpret. But TBD on what that means for CBD. So unless you live in a state where marijuana is cleared for recreational use and you’re over the age of 21, the answer to whether or not CBD is legal where you live will vary. And avoid transferring even the most harmless of CBD over state lines. Per Quartz:
That lines up with one of the rare instances of FDA testing. In 2016, the FDA tested several “CBD oils,” ultimately issuing warnings to eight companies. Some of those oils were found to contain no or barely any CBD, and many contained illegal quantities of THC. For example, Healthy Hemp Oil’s “Herbal Renewals 25% CBD Hemp Oil Gold Label” contained 8.4 mg/g of THC. Sana Te Premium Oils, which sold 25 mg “CBD oil” capsules on Etsy, contained between 13 and 19 mg/g of THC and less than 0.1 mg/g of CBD.
Hello Tracy I’ve been a nurse for 14 years. Some strains of cannabis can have amazing effects for patients with severe IBS. Most people find that a full spectrum product containing CBD, CBG, CBN, as well as active plant lipids, phytochemicals and a small amount of THC is most effective for calming the bowels and treating pain. It is usually the sum of all these active parts TOGETHER that creates something called the entourage effect and the most efficacious cannabis for treating a disease state such as IBS.
Strain-specific topicals attempt to harness certain terpenes and cannabinoids in a chemical profile similar to that of Blackberry Kush, Permafrost, Blueberry, or whatever other strains the processor wishes to imitate. Along with THC, CBD, THCA, and other cannabinoids, topical producers may also select ingredients and essential oils for additional relief, like cayenne, wintergreen, and clove.
I live in Utah so I have no way to get Harlequin CBD. Is there anything even close to that, that doesn’t need a medical card to purchase. There are so many BS CBD hemp companies that are not trustworthy and I don’t want to waste anymore money trying to find something. My son loves his school or we would have moved already. Help! I need a legit CBD hemp company to buy tincture and capsules. Leafy is my go to because so far all the info always checks out.

I am just starting to look at cannabis for pain management/healing/improvement in my health. I am 53 and as of right now have been diagnosed with bone on bone arthritis in my hips. But that is not the only issue. Even though the joints hurt, I have some extreme pain in my butt and legs, due to inflammation and muscles tightening up. I lose a lot of sleep, and am limited to how far I can walk, and am using a cane or walker to get around. I have no Health Insurance, but have gone to a clinic to receive an anti-inflammatory prescription, and minimal amount of muscle relaxants… 30 pills for a month, as the doctor fears I will become addicted. Both meds have helped, but I still have lots of pain. Can anyone share their experience on how CBD Hemp oil, or other cannabis products have helped them? I live in California, which just passed recreational marijuana use into law. Would this mean that you can get Hemp oil/ marijuana extract without a prescription? if so, where? So many questions! I know that most days, when I am not sitting down, my pain can reach 8-12 on a scale of 1-10, so I am really anxious to find something that will work! TYIA 🙂
Our Editor’s Pick is the tincture from CBDistillery.

The tincture has a price-point that is slightly below average, making it a good option for value seekers. The tincture, which is non-flavored, routinely undergoes third-party testing to ensure safety and high quality; the testing results are available on CBDistillery’s product pages.
THC oil, marijuana oil, and cannabis oil are generally associated with the same product. Essentially, they all mean the same thing. With the help of alcohol, this oil is made by extracting the resin of the female marijuana plant. Remember, the marijuana plant is the high-THC strain. The resin dissolves in alcohol and then the alcohol evaporates. The residue will consist of a thick syrup abundant in THC. This type of oil is illegal because of the high levels of THC.

If the ECS is affected, or the body is not producing enough endocannabinoids, these functions in the body may become unbalanced. And when the body is not producing or regulating endocannabinoids properly, ingesting natural cannabinoids or applying them topically can restore this balance. CBD differs from THC in the sense that THC mimics the natural cannabinoids in the body and binds with the cannabinoid receptors CB1 and CB2, which are found in abundance within the immune system, the gastrointestinal tract, and in the central and peripheral nervous systems. While THC binds to these receptors, CBD interacts with an enzyme called FAAH (fatty acid amide hydrolase).4
Hemp Oil is also from the Cannabis Sativa plant but only the seed is cold-pressed to obtain the oil. It is also called Hemp Seed Oil.  It is not tested for C B D content but most likely contains a small amount as it is from the Cannabis Sativa Plant.  Hemp Oil is regulated in its production and is tested for THC amounts but is not tested for C B D amounts.
