Basically, cannabis is an umbrella term that includes both hemp and marijuana plants. Cannabis sativa is actually the scientific name of the cannabis plant (Cannabis = genus; sativa = species), and hemp and marijuana are just two different “varieties” of it (i.e. you could refer to both marijuana and hemp plants as “cannabis” plants, but you would not, for instance, refer to a “marijuana” plant as a “hemp” plant). Hopefully that’s not too confusing.
CBD oil is not legal everywhere. It is banned/restricted by countries such as UAE, Dubai, and Saudi Arabia. Although CBD oil is illegal in many of the US states too, some have legalized its use for medicinal purposes. While the number would be ever-changing, as of 2016 there are 17 states in the US which have legalized the use of low THC, high CBD products for medical reasons in limited situations. These states include Alabama, Georgia, Iowa, Kentucky, Florida, Mississippi, Louisiana, Missouri, North Carolina, Oklahoma, South Carolina, Wisconsin, Wyoming, Tennessee, Texas, Utah, and Virginia. It is advisable to consult your local health specialist before use.

Isolates are typically the CBD oil product of choice for those who get drug tested or are sensitive to other cannabinoids such as THC. Products labeled as isolates will generally be highlighted as being 99+% “pure CBD.” Usually, these products will have nothing but CBD in them because the CBD has literally been isolated from everything else. You can find pre-made isolate oils that typically consist of a carrier oil, such as MCT oil, infused with the crystalline isolate powder. You can also find the “raw” CBD crystalline powder or slabs (a form of concentrate) on its own.
With that being said, let’s discuss the wonderful thing we call CBD oil. CBD, cannabidiol, is one of over 85 active cannabinoids identified in hemp and other cannabis plants. CBD oil is derived from hemp, due to its abundance naturally occurring in the plant. CBD oil is extracted using the whole plant, stalks or flowers. Since hemp contains only trace amounts of THC, CBD oil products are non-intoxicating. 
Extracting CBD from the hemp plant is just one part of the process for making CBD hemp oil. Extracted CBD oil is less than palatable. If the consumer’s desire is to make CBD oil part of their everyday routine, producers try to make the oil at least a little bit tasty. Also, consumers require a choice when it comes to the product’s potency, or the strength of the CBD oil-based product. Producers then need to dilute the raw CBD oil to accommodate their needs.
Industrial production of CBD oil is done by combining the cannabinoid rich plant with other compounds like CO², butane, ethanol or olive oil etc., all of which leave their residues in the final product. The most important part of CBD oil extraction is selection of right plant for the extraction of oil. Cost of final product will depend on its potency and purity which is controllable only via oil extraction technique.
Healthy folks vaguely looking to add a little spring in their step (via better sleep, reducing anxiety, or easing muscle soreness) drizzle a little oil into their smoothie or latte. They might also spot-treat with a dab of oil in problematic areas. In the past several years, published papers have suggested that the compound can help with a spectrum of medical conditions, including anxiety, Alzheimer’s disease, addiction, arthritis, inflammatory bowel disease, fractures, migraines, psoriasis, and pain. In an animal study, purified extracts of CBD and THC appeared to slow the growth of a type of brain tumor.
You need a series of chambers for CO2 extraction. Their role is to control pressure and temperature. The pressure and temperature in the chambers force the CO2 cannabinoid solution to react with one another and then separate. As the cannabinoids separate, the chambers collect them separately. The extractor can then choose which cannabinoids to put into their product or products.
There has been a fair amount of confusion surrounding the legality of CBD oil. But while the vast majority of cannabinoids are controlled substances under the Misuse of Drugs Act, rest assured that CBD oil is legal across the UK for medicinal purposes, provided it has been derived from an industrial hemp strain that is EU-approved. These strains contain very little to no THC (the psychoactive cannabinoid).
And, if you do luck out and get a tincture truly containing CBD, you'll likely dish out $200 or so to take 10 to 40 milligrams daily. Since research participants take closer to 1,000 milligrams a day, it's hard to imagine a benefit without drinking the whole (expensive, calorie-dense) bottle, Tishler says. "Most people will adjust their doses based on what they're comfortable spending," Asquith says.

Your statement about cannabis being illegal is misleading. Cannabis is the plant/herb itself. The difference in what is legal vs illegal to all states is the flower of the herb containing THC. Anything < 0.3% is regarded as HEMP as the constituents lack enough of the THC compound to create the psychoactive effect. MARIJUANA is known for the psychoactive effects. They are both forms of CANNABIS.
For applications where pure CBD isn’t required, full spectrum CBD oil is the better alternative, as it provides patients the ancillary benefits associated with the many other cannabis compounds. However, important to note, is the issue of what medical conditions are best treated by either pure or full spectrum CBD oil, given the research is in its infancy. 

“Marijuana and industrial hemp are different varieties of the same plant species, Cannabis sativa L. Marijuana typically contains 3 to 15 percent THC on a dry-weight basis, while industrial hemp contains less than 1 percent (Blade, 1998; Vantreese, 1998). Most developed countries that permit hemp cultivation require use of varieties with less than 0.3 percent THC. However, the two varieties are indistinguishable by appearance. DeMeijer et al. (1992), in a study of 97 Cannabis strains, concluded that short of chemical analysis of the THC content, there was no way to distinguish between marijuana and hemp varieties.” http://www.ers.usda.gov/media/328202/ages001eb_1_.pdf
While cannabidiol (CBD) is all the rage at present, it is often hard to understand what you are getting. Furthermore, with so many different CBD products on the market, it’s hard to tell which are full spectrum, which are not and which products are made from CBD cannabis or CBD hemp.  In this article we will try to clear up any confusion, focusing the major part of the post around Full Spectrum CBD oil.
“What is CBD oil” may be your first question, but the real question we have to answer is, “What does CBD oil do?” CBD interacts with the body through the endogenous cannabinoid system (ECS) or endocannabinoid system. First discovered in the late 1980’s, the endocannabinoid system regulates the body’s homeostasis, or general state of balance, impacting such functions as mood, sleep, appetite, hormone regulation, and pain and immune response. Like an acrobat on a highwire, as the environment around us impacts our normal balance, the endocannabinoid system “corrects” by mediating our body’s reaction to keep us level.
