A group of 15 patients who received CBD over a period ranging from one month to one year were surveyed to gather various data. The researchers sought information about the patient and the caregiver, changes observed in the seizures, neuropsychological effects, side effects and the family’s overall perception following the use of cannabidiol. This simple observational study identified some very encouraging findings:
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.
CBD may offer an option for treating different types of chronic pain. A study from the European Journal of Pain showed, using an animal model, CBD applied on the skin could help lower pain and inflammation due to arthritis. Another study demonstrated the mechanism by which CBD inhibits inflammatory and neuropathic pain, two of the most difficult types of chronic pain to treat. More study in humans is needed in this area to substantiate the claims of CBD proponents about pain control.
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.
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.
Another point worth clarifying is the difference between hemp seed oil (or hemp oil) and CBD oil. There’s confusion on this point for the very good reason that both CBD oil and hemp seed oil are extracted from the industrial hemp plant. But there’s a big difference between the 2. Hemp seed oil has been pressed from hemp seed, and it’s great for a lot of things — it’s good for you, tastes great, and can be used in soap, paint — even as biodiesel fuel.
Transparency: cbdMD seems to be going through a transition with their third-party testing practices. Until recently, they only released a lab report for the CBD concentrate they use for all their products, but would not show potency testing for individual products. That seems to be changing. Currently, the only lab report on the website is for their concentrate (and it’s over a year old). But if you contact customer service, they’ll send you a lab report for any product.
Cannabidiol hemp oil, or CBD hemp oil, is made from high-CBD and low-THC hemp, unlike medical marijuana derivatives that often contain high quantities of tetrahydrocannabinol (THC). CBD hemp oil, a natural botanical extract of the common hemp plant, is therefore non-psychoactive. And, whereas in the cannabis plant CBD is the second most abundant cannabinoid after THC; in hemp it dominates the cannabinoid makeup, as THC is found only in trace amounts. CBD’s myriad of health benefits, however, are still present.
These trichomes are tiny, hair-like crystals that cover the leaves and buds of the cannabis plant. Trichomes product the hundreds of known cannabinoids that can be found in cannabis. Of the 100+ cannabinoids that have been identified in the cannabis species, CBD and THC have been studied the most extensively for their role in the endocannabinoid system.
As the CBD oil market continues to grow, more and more products are being sold online or in your local health food stores. You can find many types of CBD and each one is used in a different way. The most common forms of CBD available include the following. (Of course, you should always consult your healthcare professional prior to using CBD and read and follow all label directions.)
Lisa Hamilton, a jeweler and doula in Brooklyn, NY, knows about the side effects. She recently tried CBD for the shoulder pain that plagued her five years after an accident. Her doctor certified that she was in chronic pain, which under New York State law allowed her to buy from a state dispensary. One Friday, she swallowed two 10-mg capsules, the amount recommended at the dispensary, then took another two on Saturday. “By Sunday, it felt like I’d gotten hit by a truck. Every muscle and joint ached,” Hamilton says. She cut back to one pill a day the following week, but still felt hungover. She stopped after that.
While animal experimental data clearly suggest a potential benefit, supportive clinical data are quite sparse. In a case-control study of 308 cases of new onset seizures, Brust and colleagues found that marijuana use was significantly less prevalent among men who had unprovoked seizures compared to case controls (9). This difference was not significant in women. The authors suggest a potential protective effect against seizures with marijuana use; however, this should be considered speculative.
To make matters more confusing, nine states (including California, Washington, and Colorado) let residents buy cannabis-based products with or without THC. Nearly two dozen other “medical marijuana states” allow the sale of cannabis, including capsules, tinctures, and other items containing CBD or THC, at licensed dispensaries to people whose doctors have certified that they have an approved condition (the list varies by state but includes chronic pain, PTSD, cancer, autism, Crohn’s disease, and multiple sclerosis). Sixteen more states legalized CBD for certain diseases.
Moreover, a patient survey conducted by Project CBD, declared that “…cannabis appears to be an effective pain management tool with few negative side effects.” The study went on to say that a “…significant decrease in opiate usage among elderly patients while taking medical cannabis [was observed during trial].” In short, it has been portrayed clearly numerous times through valid and well-publicized clinical studies that cannabis is a practical option in terms of efficient pain management.
