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.
Many people are tempted to believe that products that contain CBD only are the best, thinking that using just CBD alone is a more effective treatment. While products that contain single-molecule CBD, meaning that you won’t find any other compounds, are already provided as medicines, they are not exactly more efficient than whole plant extract CBD oil, when it comes to therapeutic effects.
There’s no definite amount that’s appropriate for everyone, but the ratio of CBD to THC will indicate how psychoactive the product is and if it’s legal in your state. The more CBD compared with THC, the less of a high, and vice versa. “Managing psychoactivity is key to successful cannabis therapy,” says Lee. “Amounts should be made clear on the label and lab-certified so people know what’s helping them and what’s not.”
CBD has been in the news before, as a possible treatment for epilepsy. Research is still in its early days. Researchers are testing how much CBD is able to reduce the number of seizures in people with epilepsy, as well as how safe it is. The American Epilepsy Society states that cannabidiol research offers hope for seizure disorders, and that research is currently being conducted to better understand safe use.

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). 
Sub-lingual CBD drops have helped me enormously with sleeping and with radiation damage pain. I have a cancer that spread from the pelvic area to my sacrum and sciatic nerve and whilst the chemo and radiotherapy saved my life I have been taking MST (morphine derivative) for nerve pain ever since. My tumours are presently all quiet and last March I decided I wanted to stop taking the pain relief drugs, fearing dementia. CBD oil was recommended by my son who has arthritis and, for me, it really works. It’s so good to read an article that isn’t put out by a CBD sales site – I wish it could be properly prescribed and regulated (I’m in the UK) in order to have confidence with purity and dosage.

 Arterial Ischemic Stroke occurs when blood flow in an artery to the brain is blocked due to narrowness of the artery or the formation of a blood clot. Neonatal (i.e. newborn) Arterial Ischemic Stroke grimly means there is a condition specific to infants. Woefully little is known about NAIS, but it can certainly lead to lifelong disabilities and/or brain injury. Currently, there is no effective treatment.
CBD stands for cannabidiol. It is the second most prevalent of the active ingredients of cannabis (marijuana). While CBD is an essential component of medical marijuana, it is derived directly from the hemp plant, which is a cousin of the marijuana plant. While CBD is a component of marijuana (one of hundreds), by itself it does not cause a “high.” According to a report from the World Health Organization, “In humans, CBD exhibits no effects indicative of any abuse or dependence potential…. To date, there is no evidence of public health related problems associated with the use of pure CBD.”
CO2 extraction is one of the most common ways CBD is extracted from the hemp or cannabis plants. This method uses expensive equipment that adjusts temperature and pressure to extract the cannabinoids from the plant material, without damaging them. The other common method is to use solvents like ethanol or butane to extract the plant material. These solvents have to be burned off the final product which may damage the cannabinoids or terpenes in the process. There is also a risk that these solvents may not have burned off completely and could end up in your end product.
When it comes to using CBD, questions keep coming up, especially from people who try CBD for the first time. Since there are different CBD products and because CBD can be used in different ways, the question of how to use CBD oil is quite legitimate.  What CBD products are available, how they can be used, and the bioavailability of each product is covered in this article.

There’s a growing consensus that cannabis is a highly effective treatment for many kinds of neuropathic pain. A 2015 study published in Neurotherapeutics states, “Clinical studies largely affirm that neuropathic pain patients derive benefits from cannabinoid treatment.”   But much of the human-based research (like this study) on CBD and nerve pain has centered around the efficacy of the FDA-approved medication Sativex, which includes both THC and CBD. Research on the best CBD for pain isolated from THC is still limited when it comes to neuropathic pain. There are exceptions, though:
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.
