Immediately after reading this article I realized this is not the difference I was expecting. While the USDA says that it takes a chemical analysis to tell the difference between hemp and medical marijuana, for most of us it would only take 2 seconds to notice the difference between a field of hemp and a medical marijuana grow operation. As far as definition is concerned the two are not so far off from one another. Hemp and marijuana are both cannabis and it would seem that the only real difference is that “marijuana” or more recent term “medical marijuana” is classified as a variety of cannabis with a high percent of THC and, occasionally, high CBD as well.
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 isolate is pure CBD, extracted and purified until none of the plant’s other constituent compounds remain. It has been isolated down to just the CBD molecule. This purity and potency is why it’s the preferred treatment for patients needing unadulterated doses of CBD and nothing else. It has no other active ingredients and its purpose is simply to deliver therapeutic doses of CBD. CBD isolate products often come as a white powder or a mix with a oil.
Yes: CBD extracts can’t always be trusted. A 2017 JAMA paper reported that almost 70 percent of all CBD products sold online do not contain the amount of CBD stated on the label. Of the 84 products bought from 31 different companies, 42 percent contained a higher concentration of CBD oil than the label claimed, and 26 percent of the products contained less than the label claimed. The remainder of products contained the labeled amount—give or take 10 percent.
It probably depends on each individual’s preference, but many researchers support the effects of the full spectrum CBD. They say that the full spectrum’s healing factors through the “entourage effect” are very useful for the treatment of any of the chronic condition. This is why the full spectrum CBD has to be part of the ingredients, not the isolate non-pure one.
"If it proved effective for anxiety, depression and panic disorder, it may have other effects as well that could be useful and beneficial [but] this is a really early stage," says David Shurtleff, the acting director of the National Center for Complementary and Integrative Health. His organization's stance: "Take it one step at a time and do the work and really state where we are right now with the research," he says.
Blood pressure. Scientists say that CBD can also aid the lowering of blood pressure in humans, mainly by reducing the body's systolic pressure in the arteries as the human heart pumps blood. By taking a moderate dosage of CBD oil, some health experts say, an individual can improve blood flow, lower the heart rate and reduce the anxiety the stress often found in patients with high blood pressure.
Recently I asked myself this very question and the more I read the more contradictory statements I found and the more confused I became. With an extensive background in medical marijuana and high THC strains I felt I had a good grasp on which one was “better” before I started researching for this article and could make a good argument for why medical marijuana derived CBD is better than hemp derived CBD. More recently I have been introduced to CBD derived from hemp and after some preliminary research I was not so sure. Fortunately, I have connections from within the industry and so my mission began. I set out to talk to the largest names on both sides of the spectrum and get their opinions on this matter.
The same terms could be applied to what's actually in CBD products. While some do contain CBD, others (often marketed as "CBD-rich hemp oil") may have barely any, Asquith says. And depending on state laws, they can include varying levels of THC too – a combination shown to have some benefits, but also drawbacks, of course, if you're not looking for a high. "People will play all these games with the numbers because the consumers aren't really educated in this space yet and it's easy to get taken advantage of," he says. "It's the milligrams of the actual CBD molecule that matter."
‘I recommend starting with a low dose and slowly building up over a few weeks, to find the dose that works best for you,’ agrees Dr Brewer. ‘For example, start with Healthspan High Strength CBD Oil 6.4mg Capsules, taking one to three daily. Then, if needed, move up to Super Strength CBD 15mg Capsules, taking one to two daily. CBD is not psychoactive and is not addictive. I prefer capsules, as CBD drops have a strong taste, although filter-clear peppermint flavoured drops are available.’
Supercritical CO2 extraction is also the key to understanding more cannabinoids in cannabis like Cannabichromene (CBC) and cannabicitran (CBT) and how they interact with each other (called the Entourage effect). This can lead to increased understanding of marijuana in the medical field, and will also allow growers to come up with more effective, new and exciting strains.
“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
Under federal law, cannabis (from which both CBD and marijuana are derived) is illegal everywhere, although the laws against it aren’t generally enforced in states that have legalized marijuana. Some manufacturers claim that CBD culled from legally imported industrial hemp, which has little to no THC, is fine to ship across the U.S., but many experts disagree, noting that because hemp comes from the same species as marijuana, cannabis sativa, all CBD falls under the DEA’s Schedule 1 designation. “This creative interpretation of the law runs afoul of reality,” says the Brookings Institution, a Washington, DC, think tank.
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.
