Confused yet? That's okay; it's easy to get that way given all the different CBD oils on the market as well as all the different hemp products. Hemp is actually an amazing plant, with a lot of potential uses beyond anything related to CBD, though perhaps that's a good topic for another time...though we're going to briefly touch on it.
So what's the difference?
There's a difference between a "hemp oil" and hemp-derived CBD oil.
Hemp seeds, just as many plant seeds do, contains a certain amount of oil, which can be extracted and then refined. Now, this doesn't mean that the oil in hemp seeds is the same as CBD oil (more on that in a moment) but it's more that, again, the seeds themselves contain oil.
Since the term "hemp oil" is incredibly ambiguous, any oil that's extracted from hemp plants in any way, shape or form is itself "hemp oil" and thus includes the more specific "hemp seed oil."
Hemp seed oil, in and of itself, can be used for a variety of uses including food-grade applications or, since the oil is rich in hydrocarbons, can also be refined into biodiesel.
That's right; hemp can be used to make fuel for vehicles. Granted, not much is done with it since the cost per barrel (given the size of current hemp crops in North America) works out to more than ten times that of the current per barrel cost of crude petroleum.
There are many different kinds of hemp oil. However, what most people mean when they say "hemp oil" is something more like "hemp CBD oil." As it happens, not all CBD oil is hemp oil. Some of it is, some of it isn't, and some of it is a blend of CBD from various sources.
CBD oil, in and of itself, is an infusion of CBD and a carrier oil, often enough a neutral-flavored food oil such as vegetable oil, MCT oil and in some cases even olive oil if you want your CBD to have that classic Mediterranean flavor. Naturally, the latter is more common for people who are making CBD oil at home.
In and of itself, cannabidiol can be extracted from any plant that happens to contain it. The plants that contain the most of it, and therefore can be used reliably to extract CBD, are the marijuana and hemp plants.
As has been pointed out many, many times, the two plants are virtually identical except that marijuana plants contain sufficient levels of tetrahydrocannabinol (THC) to be psychoactive if ingested by humans. Hemp, of course, does not contain enough THC to do so...unless you consumed a truly staggering amount.
Now, the source of the CBD depends on who makes it. Some extract it purely from hemp plants, some purely from marijuana plants, and some from both. That doesn't necessarily mean that such oils contain THC; CBD oil must, by law, contain less than 0.3 percent THC by weight in order to be sold as "CBD oil" or else it has to be labeled a THC tincture and sold only in states with less-strict marijuana laws.
So, it can therefore be said that not all CBD oil is purely hemp oil as some CBD oils use CBD extracted from marijuana plants as well as from hemp plants.
Hemp CBD oil, from a reputable manufacturer, is totally safe and uses a source material that is beyond reproach. Granted, CBD oil that includes CBD sourced from marijuana plants is not terrifically different chemically, but because marijuana is involved...it gives some people the jitters in terms of worrying about the ramifications about its use.
Therefore, many people prefer pure hemp CBD oil to different oils as they just don't want to have to worry about anything, especially given the pernicious nature of governmental regulations.
At the moment, hemp products are totally legal nationwide, including hemp CBD products; there's no need to worry that some state legislature - or Congress, for that matter - will change their mind and make the product that makes their life better illegal just because the marijuana plant was involved at some point in the supply chain, even if the product contains basically no THC.
but you can opt out at any time.
