Generally, CBD oil is made by combining an extract with a carrier fluid or oil. This question is best answered by looking at how the CBD oil was extracted. CBD oil can be extracted using CO2 systems or by using chemical solvents. Both methods produce a CBD oil byproduct that is then combined with a fluid like MCT oil, coconut oil, or olive oil so that it can be delivered to the body. Always check to make sure you know the CBD content of the products you purchase.

Californians also have to take into consideration Prop 65. This proposition requires that businesses refrain from knowingly and intentionally exposing individuals to any of the chemicals contained in a state-published list of chemicals which are known to cause cancer or reproductive harm. This, among many other factors, is why HempMeds adheres to the Triple Lab Tested® Standard. We believe in a common sense approach where safety and knowing what goes into your body is of utmost importance.

However, like we just mentioned CBD oil for pain management that has been sourced from industrial hemp grown under the farm bill is in fact legal to buy and sell. The best CBD oil brands that we cover here on this site, claim to extract their concentrates from U.S.-based industrial hemp supplies, which if true, are 100% legal since they contain negligible amounts of THC.
CBD is a compound found in the hemp plant, also known as Cannabis Sativa L. CBD products that are available on the market, such as Green Roads products, are made from industrial hemp. The main difference between hemp and industrial hemp is that the latter has Non-Detectable THC. THC, or tetrahydrocannabinol, is a psychotropic chemical found in cannabis. The CBD products available to all customers in the U.S. contain very small amounts of THC.
Multiple sclerosis (MS). There is inconsistent evidence on the effectiveness of cannabidiol for symptoms of multiple sclerosis. Some early research suggests that using a cannabidiol spray under the tongue might improve pain and muscle tightness in people with MS. However, it does not appear to improve muscle spasms, tiredness, bladder control, the ability to move around, or well-being and quality of life.

Multiple sclerosis (MS). A prescription-only nasal spray product (Sativex, GW Pharmaceuticals) containing both 9-delta-tetrahydrocannabinol (THC) and cannabidiol has been shown to be effective for improving pain, muscle-tightness, and urination frequency in people with MS. This product is used in over 25 countries outside of the United States. But there is inconsistent evidence on the effectiveness of cannabidiol for symptoms of multiple sclerosis when it is used alone. Some early research suggests that using a cannabidiol spray under the tongue might improve pain and muscle tightness, but not muscle spasms, tiredness, bladder control, mobility, or well-being and quality of life in patients with MS.
Despite the many states that have legalized some or all forms of marijuana, federally the U.S. Drug Enforcement Administration (DEA) continues to classify CBD as a Schedule I drug. Schedule I drugs are defined by the DEA as "drugs with no currently accepted medical use and a high potential for abuse." This is how not just CBD, but the entire cannabis plant is classified.
Transparency: Fab’s website features third-party lab results for most products. They only have a lab test for one of their tinctures though (which shows results for cannabinoid potency, as well as contaminants like pesticides). Customer service pointed out that the same CBD oil is used for all their products, but since potencies do vary, we appreciate companies that show potency testing for all products.
In 2015, Governor Greg Abbott signed into law what’s known as the Texas Compassionate Use Act, which allows the use of CBD oils to treat seizures caused by intractable epilepsy. The Act legalizes oils containing CBD for treatment of epilepsy, as well as other chronic medical conditions for those who have not responded positively to use of federally approved medications.
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. 
House Bill 2107 was brought during the 2017 legislative session with a number of vocal supporters. The bill sought to remove the “low THC” restriction and amend the law to allow for “medicinal marijuana.” It also sought to expand the types of conditions that can be treated with cannabis by including post-traumatic stress disorder and terminal cancer. Finally, the bill sought to modify the language, from requiring a doctor’s prescription to requiring a doctor’s recommendation. This change intended to address concerns about the legality of physicians prescribing something prohibited by federal law. Despite having 77 sponsors and co-sponsors, 29 of whom were Republican, the bill died in committee. Given strong support, as well as national trends, changes in Texas law are likely to occur in the future.
CBD oil has been explored as a potential treatment for schizophrenia. Human trials are a little more advanced when it comes to using CBD oil to treat psychological problems. A 2012 study by a team of nine researchers in Germany, Italy, and the United States investigated the effects of cannabidiol on brain activity in patients with a diagnosis of schizophrenia (3). 
As of early 2017, 14 of these regulated 33 states legally produce hemp seeds. The federal designation indicated hemp could be grown for industrial or academic applications. These 14 states (CA, CO, IN, KY, MA, MO, ND, OR, SC, TN, VT, VA, NC and WV) are producing hemp seeds for industrial use. While regulations and agricultural standards are still developing in America, European sourced is still the ideal choice for the consumers. Ideal conditions, more experience, and refinement of regulations to ensure safety and quality lend more trust to you, our consumer.
