There is a significant amount of scientific research on CBD and the ECS system as well as journal entries from pilot studies done by doctors from around the world over the past four decades. However, as this is still a novel area of medicine, do your own research on CBD. There are many online sources of information, but note the internet has a mix of both valid and misleading data. Vet your sources to ensure that they are reputable.

Most CBD oils are available in round-number concentrations such as 250mg, 500mg, and 1,000mg. While these strengths accommodate many CBD users, they may not be sufficient for those with preferences that fall outside round numbers. NuLeaf Naturals offers a less conventional selection of concentrations: 240mg, 725mg, 1,450mg, 2,425mg, and 4,850mg. This range ensures that most users will find a strength that works for them.
But one of the big differences between CBD and THC is, according to Jane West, cannabis activist, entrepreneur, and founder of the marijuana networking group Women Grow, that CBD is non-intoxicating. “Its potential benefits come with few or no adverse effects,” West tells MarieClaire.com. “So really, this is something that everyone, even those who are reluctant to consume cannabis, can try to incorporate beneficial cannabinoids into their lives without any sort of high or residual THC in their bloodstream.”
Scientifically, the difference between what we refer to as hemp and marijuana comes from the intention the strain was bred for. The main difference between hemp and marijuana is the level of THC in the plant. Hemp has high levels of cannabidiol (CBD) and very low levels of tetrahydrocannabinol (THC). Marijuana is recognized for having high levels of THC and lower in CBD. In order to be considered hemp, the plant must have less than 0.3 percent THC. High levels of THC are responsible for the intoxicating feeling that marijuana is known for.
Research and regulation of cannabis in general is decades behind other crops and drugs because of its long prohibition. We’re in the early stages of a chaos period that will last a decade at minimum — a substance has to be legal in order for scientists to figure out how it works and for the government to figure out how to ensure it’s safe. Clinical trials take years to complete and will have to build on each other to create a competent understanding. Coupled with modern technology’s ability to disseminate truths, half-truths, and complete lies, this means we’re in a phase ripe for scams, intentional and not.
Still, as the saying goes, absence of evidence isn’t necessarily evidence of absence, and there’s a reason we don’t have a ton of solid research on CBDs yet — “to study it, we need a good source, ” said Ziva Cooper, who is an associate professor at Columbia University and was on the National Academies committee. CBD is hard to get because it’s still technically a Schedule I drug, which limits its availability, Cooper said.
This takes us to the next problem: There is no regulation around how much active CBD or THC is in each cream or how much of the compound is needed to see relief. Read: "If you have three products that say 1 percent CBD infused in coconut oil, one could be great and the other two could be crap—that's the reality of cannabis medicine right now," Gerdeman says.
Pro skateboarder Matt Miller, who started CBD brand Miller Healer, turns to CBD sports salve and patches as his primary medicine. Stacy Verbiest, who founded therapeutic women’s cannabis line Wink with creams and tinctures, says CBD helped her friend manage the pain of cancer treatments. Pet owners buy cat and dog treats with the hopes of helping their best friend feel happier and more comfortable.
The 2016 European Journal of Pain conducted a study on rat models to test the effectiveness of CBD against arthritis in order to see if it could serve as an all-natural alternative to the typical arthritis pain medications, which are often tied with numerous uncomfortable and frustrating side effects. The rats were treated for 4 days with 4 different doses of CBD gel, and the results were quite staggering.
Although a range of analytical methods have been published in recent years , there is no general agreement on which analytical method is most suitable and accurate. Additionally, there are currently no generally accepted guidelines or certifications to determine the qualifications of cannabis labs. As a result, cannabinoid analysis can differ significantly between labs , even when the exact same sample is analyzed multiple times . This not only poses a risk to consumers (who do not know how trust the label on their product) but may also lead to business-to-business conflicts about the quality or value of intermediate products. Additionally, inaccurate analytical results may lead to legal problems if the THC content of a CBD product unexpectedly turns out to be higher than the maximally allowed limit. It seems clear that a better agreement on the conditions for lab testing of cannabinoids is urgently needed.
The term "CBD" is a nickname for cannabidiol, which is one of several cannabinoids, or chemical compounds, that are found in cannabis and hemp plants. Of course, the most famous cannabinoid is tetrahydrocannabinol, or THC, which is the main psychoactive component in marijuana (aka, the part that gets you high). Because CBD is not psychoactive, it does not create the same buzzy effects typically associated with marijuana when ingested.
Recently, an interesting study performed in the Netherlands highlighted multiple issues that may be extrapolated to CBD products elsewhere . In this study, 46 different cannabis oil samples were collected directly from patients and analyzed for cannabinoid content. The obtained samples were home-made (n = 29) or purchased from a (web) store (n = 17). For 21 of the 46 products (46% of all samples), label information was available on CBD/THC content, so that the claimed content could be compared to the analyzed content as determined in the study. Results are shown in Table 1. In many cases the analyzed cannabinoid content strongly differed from the claimed content on the label, while in 7 samples no cannabinoids (CBD or THC) were found at all. Such deviations were found in home-made as well as commercially obtained products.
Donald Abrams was a member of the committee that reviewed the evidence that went into producing the report, and he said that the studies they reviewed overwhelmingly used pharmaceutically available preparations that contain THC, including dronabinol, nabilone and the whole-plant extract spray nabiximols, which contains equal parts CBD and THC. It’s impossible to know whether the benefits of cannabis can also be obtained from CBD alone, Abrams said, because CBD is just one of 400 chemicals present in the plant. So far, CBD in isolation has been studied in only a handful of randomized, placebo-controlled trials (considered the gold standard of evidence in medical research), and the evidence remains sparse.
Research on low levels of CBD is, you guessed it, incredibly limited; just a single paper on the medical research database PubMed specifically looked at CBD in these low doses, as a treatment for Crohn’s disease. (It was not found to have an effect.) As such, it wouldn’t be fair to say that 5 or even 20 mg of CBD oil in your coffee is proven to do nothing; that hasn’t been proven. It’s more accurate to say that 20 mg of CBD oil in your coffee has never been proven to do much of anything, and related research indicates that’s probably way too low of a dose to have any measurable effect.
Well, much like with other cannabis products, that's kind of a gray area. On the federal level, any CBD products derived from cannabis plants are completely illegal, unless they are approved by the FDA (which only includes Epidiolex at the moment), the Drug Enforcement Agency said in September. The DEA even told VICE recently that the federal law makes no distinction between CBD derived from cannabis or hemp (a cannabis plant species with an especially low concentration of THC grown legally in roughly 40 states, mostly for industrial purposes). In other words, the official stance of the federal government seems to be that CBD products are illegal whether they are derived from cannabis or hemp.
CBD from hemp is identical chemically and therefore will cure cancer equally as well. The difference in effectiveness would be more whether it is a full spectrum product vs an isolate. As hemp does contain some THC, hemp derived CBD can be full spectrum. What you are saying is equivalent to citrus from an orange is better for colds than citrus from limes. As w CBD citrus is citrus (chemically identical) regardless of the source.
Despite this, CBD is something nobody knows much about, and certainly nobody is monitoring it properly. CBD is widely marketed as a supplement, despite the Food and Drug Administration saying it does not qualify as such (this is because it is an active ingredient in drugs which are either approved or under investigation to be approved). CBD goes largely unregulated by the agency; on the FDA’s FAQ page, a vague answer maintains there are “many factors in deciding whether or not to initiate an enforcement action.” The Department of Agriculture handles research grants and pilot programs for hemp, but that’s where its involvement ends.
