"A CBD company may create a CBD oil, test it, and use the test results to create their label," Bonn-Miller says. "The problem is if they never test their product again, or they test it once a year, you have no idea whether each batch is the same as the first one that they used to create the label. The vast majority of companies are not using manufacturing standards that assure product consistency over time. Companies should be testing every batch they make and tossing batches that don't fall within the specs of their label."
Later in 2014, researchers reported on preliminary results of a study involving children with treatment-resistant epilepsies in an expanded access “compassionate use program.” Patients received a purified 98 percent oil-based CBD extract called Epidiolex, which is made by GW Pharmaceuticals. After 3 months of treatment, 39 percent of the 23 patients had more than a 50 percent reduction in seizures, with a 32 percent median reduction. These preliminary results support the animal studies and survey reports that CBD may be a promising treatment for treatment-resistant epilepsy and it is generally well-tolerated in doses up to 25 milligrams per kilogram of body weight.

A 2013 study published in the British Journal of Clinical Pharmacology reports that CBD protects against the vascular damage caused by a high glucose environment, inflammation or the induction of type 2 diabetes in animal models; plus, CBD proved to reduce the vascular hyperpermeability (which causes leaky gut) associated with such environments.

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.
Some studies show that CBD can counteract these adverse effects, but more research is needed, as most of this research is done on animals or is based on anecdotal reports. Little research has focused on the safety and side effects of CBD in humans; however, clinical trials indicate that only a few, generally mild side effects have been observed after CBD administration and tolerance for CBD does not seem to occur.
Always start with the micro dose to test sensitivity and go up as needed within the dosing range before going to the next, until symptoms subside. The micro to standard dose is usually recommended to treat depression. Vaporized or smoked cannabis is recommended for relief of immediate symptoms, or a boost in dosage, and it can also be useful for sleep issues. Sublingual sprays or tinctures taken as liquid drops take effect quickly and last longer than inhaled products.
Nora Volkow from the National Institute on Drug Abuse reiterated the decision of (then) two dozen states to allow medical marijuana to be used in one way or another in their jurisdictions. This should open everyone’s eyes to the sanctioning of a non-addictive, non-psychoactive substance which has been linked to benefits for patients suffering from seizure disorders, quite a few neurodegenerative disorders or pain resulting from cancer.
At present, we have the following classification of cannabinoids: endocannabinoids (produced naturally in the body, mainly from fatty acid precursors), phytocannabinoids (compounds that have a plant origin, with the cannabis plant being the best-studied source of phytocannabinoids though not the only one), and artificial cannabinoids (created while studying THC, to garner the benefits of marijuana without the recreational component).
