If one takes high amounts of CBD, the cannabinoid can temporarily neutralize the activity of P450 enzymes and thus alter the way drugs are metabolized inside the body. This action of CBD can be regarded as a side effect, but it’s not always a negative trait, as the deactivation of P450 enzymes is one of the mechanisms through which CBD neutralizes THC as well.
This is good news for the best CBD oil companies because the Farm Bill allows for the legal cultivation of industrial hemp, under certain circumstances, which can be a source of CBD. But CBD can also come from non-industrial hemp, namely the marijuana plant that most are more familiar with. Therefore, whether or not CBD oil for pain is legal can be a question of which “version” of the cannabis plant it was sourced from. If it was sourced from industrial hemp, (which contains less than 0.3% THC by volume), and it was cultivated under the Farm Bill, then it is legal.

Because CBD oil products are mostly unregulated, there’s no guarantee that any given product contains a safe or effective level of CBD. In fact, a study published in the Journal of the American Medical Association in 2017 found that nearly 70 percent of all CBD products sold online are incorrectly labeled, and could cause serious harm to consumers. Some CBD oils may also contain incorrectly labeled amounts of THC and other compounds.
CBD oil contains CBD (and often other active compounds) in a carrier oil. There are a number of forms of CBD oil, including softgel capsules, tinctures, and under-the-tongue sprays. Some forms of CBD oil can also be applied directly to the skin, in the form of products like creams and salves. The concentration of CBD varies from product to product.
Another huge benefit of CBD oil is its’ apparent effect on tumor and cancer growth. A 2006 research study published in Journal of Pharmacology & Experimental Therapeutics revealed that CBD oil potently inhibited growth of different tumor cell lines. The antioxidants present in CBD also provide anti-mutagenic properties and help lower the user’s risk of cancer. The cannabinoids compounds in the oil have the ability to directly target the cancer cells, causing a reduced spread rate and also higher cancer cell death rate.
It’s also important to select CBD oil products based on your concentration preferences. Some forms of CBD oil – such as vapors and tinctures – normally have higher-than-average concentrations, whereas sprays and topicals tend to have lower concentrations. Remember: higher concentration means more pronounced effects, but not necessarily mean higher quality.
It’s also one of the strongest and most concentrated CBD oils for pain on the market today. With a grain-of-rice-sized recommended serving taken orally twice a day, its potent punch acts quickly—in just ten to fifteen minutes—to provide powerful relief. Furthermore, it offers terrific value for your money, boasting more CBD per dollar than many other CBD products.
Back pain can be extremely debilitating, and it’s understandable if you want to steer clear of pharmaceutical painkillers in favor of something a little more natural. That’s what makes this Green Label Raw CBD Oil from Herbal Renewals so special. Available in three sizes, it’s a potent concentrate that gets to work in around fifteen minutes, and it can last for up to twelve hours, bringing real relief to back aches.
Green Gorilla marks itself out by simply blending its flagship line of CBD oils with organically produced extra virgin olive oil – and nothing else. And, as the company states, there’s a benefit to this beyond assuring the product’s purity. In particular, olive oil “has synergistic effects in combination with CBD,” and according to Green Gorilla’s website, it’s “also able to deliver the CBD to the parts of [the] body that need it most.” The products are certainly affordable, too: its 150 mg pure CBD oil comes in at $25.99, for instance, making it a smart choice for new users. And anyone still uncertain about the potential effects of Green Gorilla’s products may have their questions answered by the convenient “science” section of the manufacturer’s website, which neatly explains the difference between THC – the cannabinoid that makes people “high” – and CBD.

CBD may be best known for its relaxing, calming effects. CBD reduces autonomic arousal, having the inverse effect of THC on the body. CBD’s anti-anxiety effect is why many in the cannabis community talk about how CBD relieves paranoia, although that is not scientifically proven yet. CBD is also known for its anti-nausea and pain relieving effects. It really depends on why your body’s specific needs and the quantity in which you take CBD.
As Dixie Botanicals claims on its website, “When it comes to quality, we leave nothing to chance.” To that end, the company tests each CBD oil batch on no fewer than three occasions during the production process: once after the hemp oil it uses is extracted; then again upon the oil’s arrival in the U.S.; and, for the final time, after the substance has been put into its range of products. What’s more, Dixie Botanicals proves that such rigorous quality control doesn’t necessarily mean high price tags for customers: its 100 mg tincture drops, for example, come in at a reasonable $29.99 per 30 ml bottle. The company’s novel “Kicks,” meanwhile, combine chocolate, caffeine and CBD in handy bite-sized chews that may tempt coffee addicts and candy fiends alike.

The NCBI study does mention some potential side effects for cannabidiol, such as the inhibition of hepatic drug metabolism and decreased activity of p-glycoprotein. CBD can indeed interact with a series of pharmaceuticals, as it inhibits the activity of some liver enzymes called cytochrome P450. This family of enzymes metabolizes most of the pharmaceutical drugs used to treat humans.


Once extracted from the stalks and seeds of hemp, pure CBD hemp oil can be taken directly or infused into products like tinctures, liquids, capsules, and topicals. With demand for high-CBD hemp oil now higher than ever, there are a wide variety of CBD hemp oil products available for purchase at retailers or online with delivery straight to your door.
As more and more states legalize the use of marijuana, a product known as CBD oil has surged in popularity. A chemical compound found in the cannabis plant, CBD, or cannabidiol, is non-intoxicating and does not cause the noticeable euphoric effects associated with tetrahydrocannabinol (or THC, another marijuana compound). Products marketed as CBD oil may contain THC.
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. 
So, why are companies allowed to lie and mislead users trying to purchase CBD products? This a result of the industry lacking formal regulation. This is very controversial because it opens the doors for big pharmaceutical companies and lobbyists to get away with practices that may prevent CBD from becoming easily accessible to those who need it. Hopefully, legislation like the 2018 Farm Bill will help establish competitive practices in the industry that will benefit the consumer in the long run.
