Whether the drug and non-drug, cultivated and wild types of Cannabis constitute a single, highly variable species, or the genus is polytypic with more than one species, has been a subject of debate for well over two centuries. This is a contentious issue because there is no universally accepted definition of a species.[54] One widely applied criterion for species recognition is that species are "groups of actually or potentially interbreeding natural populations which are reproductively isolated from other such groups."[55] Populations that are physiologically capable of interbreeding, but morphologically or genetically divergent and isolated by geography or ecology, are sometimes considered to be separate species.[55] Physiological barriers to reproduction are not known to occur within Cannabis, and plants from widely divergent sources are interfertile.[43] However, physical barriers to gene exchange (such as the Himalayan mountain range) might have enabled Cannabis gene pools to diverge before the onset of human intervention, resulting in speciation.[56] It remains controversial whether sufficient morphological and genetic divergence occurs within the genus as a result of geographical or ecological isolation to justify recognition of more than one species.[57][58][59]


Israel, another example, has led the way with ground-breaking research into cannabis cultivation. The country recently recognized medical marijuana as an official part of the nation’s branch of agriculture. Israel is already one of the world’s leading exporters of medical-grade cannabis. Recognizing marijuana cultivation as an official branch of the country’s agriculture will open up even more funds to support Israeli cannabis farmers.
We all know of Charlotte’s Web; the miracle strain that is packed with a high concentration of CBD. The Charlotte’s Web Cannabis Strain was named after Charlotte Figi, who suffers from Dravet syndrome and was experiencing several seizures daily until the Stanley Brothers came up with this powerful strain. Since then, Charlotte’s web has been morphed into various products, including their famous Charlotte’s Web CBD oil.
To make matters more confusing, nine states (including California, Washington, and Colorado) let residents buy cannabis-based products with or without THC. Nearly two dozen other “medical marijuana states” allow the sale of cannabis, including capsules, tinctures, and other items containing CBD or THC, at licensed dispensaries to people whose doctors have certified that they have an approved condition (the list varies by state but includes chronic pain, PTSD, cancer, autism, Crohn’s disease, and multiple sclerosis). Sixteen more states legalized CBD for certain diseases. But because all these products are illegal according to the federal government, cannabis advocates are cautious. “By and large, the federal government is looking the other way,” says Paul Armentano, deputy director of the Washington, DC–based National Organization for the Reform of Marijuana Laws (NORML), but until federal laws are changed, “this administration or a future one could crack down on people who produce, manufacture, or use CBD, and the law would be on its side.”
THC, manufactured into a pill that is taken by mouth, not smoked, is available by prescription and can be used to treat the nausea and vomiting that go along with certain cancer treatments and to help AIDS patients eat more to maintain their weight. Another chemical related to THC, nabilone, has also been approved by the Food and Drug Administration for treating cancer patients who suffer from nausea.

Only a handful of countries have legalized recreational marijuana. Uruguay was one of the first, in 2013. The Netherlands is perhaps the country most known for legal marijuana, yet the drug is illegal there. Spain has given its citizens the rights to grow and consume cannabis privately. Peru also allows citizens to possess marijuana as long as it is for personal, private use. As in Costa Rica, where people can have a “small amount,” without legal trouble.

Experimental studies have also been conducted in order to assess the effect of cannabis use on schizophrenia. D’Souza et al. (2004) administered varying levels of the main ingredient in cannabis to healthy individuals with a history of cannabis exposure (but not abuse) and found that the subjects in the study displayed both positive and negative symptoms associated with schizophrenia, although all symptoms disappeared by about 3 h. D’Souza et al. (2005) conducted a follow-up study in which they followed the same protocol, but with clinically stable schizophrenia patients. Again, they found brief increases in positive symptoms, even if the patients were already taking antipsychotics.

Some manufacturers ship CBD products nationally, an illegal action which the FDA has not enforced in 2018, with CBD remaining the subject of an FDA investigational new drug evaluation, and is not considered legal as a dietary supplement or food ingredient as of December 2018.[71][72] Federal illegality has made it difficult historically to conduct research on CBD.[73] CBD is openly sold in head shops and health food stores in some states where such sales have not been explicitly legalized.[74][75]


One of the most experienced practitioners in this field is Los Angeles physician Bonni Goldstein, who has used the compound to treat dozens of children with intractable epilepsy. She says about half of these patients have seen a significant drop in the number of seizures. “Used in the right way, with the right patient, CBD is extremely powerful,” she says.
We would never sacrifice quality by providing a synthetic CBD or CBD isolate blend. We use a whole plant extract that is rich in cannabinoids, terpenes, and other beneficial oils. The Hadassah Medical School at the Hebrew University of Jerusalem sought to compare the effectiveness of a completely purified CBD extract versus a full-spectrum extract of cannabis flowers containing large quantities of CBD. The conclusion of the study was that the whole plant extract, which contained a large percentage of CBD but also contained traces of the other cannabinoids, proved far more effective than CBD-only solutions in alleviating inflammation and pain sensation.

Doctors advise pregnant women not to use any drugs because they might harm the growing fetus. Although one animal study has linked marijuana use to loss of the fetus very early in pregnancy, two studies in humans found no association between marijuana use and early pregnancy loss. More research is necessary to fully understand the effects of marijuana use on pregnancy.
Though unflavored and priced higher than competitors, Green Roads CBD oils are made by a trusted manufacturer and use organically grown hemp. Following the CO2 supercritical fluid extraction process, board-certified pharmacists formulate the tincture by hand. Green Roads only sells CBD isolates, so if you’re looking for broad-spectrum products look to some of our other recommendations.
Keep in mind that CBD levels may vary from crop to crop—even from plant to plant. However, below are some strains that have been bred to contain higher CBD levels, so they might be a good place to start. Check the map on their strain page to see if these are sold at a dispensary near you. We also recommend checking with dispensaries about the specifics of their strains’ CBD levels. It’s always a good idea to purchase only lab-tested products that clearly state the CBD/THC levels so you know what kind of experience to expect.
A 2015 review found that the use of high CBD-to-THC strains of cannabis showed significantly fewer positive symptoms such as delusions and hallucinations, better cognitive function and both lower risk for developing psychosis, as well as a later age of onset of the illness, compared to cannabis with low CBD-to-THC ratios.[278] A 2014 Cochrane review found that research was insufficient to determine the safety and efficacy to using cannabis to treat schizophrenia or psychosis.[279] As of 2017, the molecular mechanisms for the anti-inflammatory and possible pain relieving effects of cannabis are under preliminary research.[280]
The genus Cannabis was formerly placed in the nettle (Urticaceae) or mulberry (Moraceae) family, and later, along with the genus Humulus (hops), in a separate family, the hemp family (Cannabaceae sensu stricto).[45] Recent phylogenetic studies based on cpDNA restriction site analysis and gene sequencing strongly suggest that the Cannabaceae sensu stricto arose from within the former family Celtidaceae, and that the two families should be merged to form a single monophyletic family, the Cannabaceae sensu lato.[46][47]
Cannabidiol (CBD) has NOT been proven to treat, relieve, nor cure any disease or medical condition listed on this site. The medical studies, controlled tests, and health information offered on Cannabidiol Life of allcbdoilbenefits.com (or any variation of the URL) is an expressed summarization of our personal conducted research done by me and few friends in the business. The information provided on this site is designed to support, NEVER replace, the relationship that exists between a patient/site visitor and the patient’s/site visitor’s physician.
Infusions: Research and opportunity have driven chefs and chemists to infuse CBD into all sorts of readily usable products, such as edibles to elixirs, sublingual sprays, capsules and even topicals. Much like concentrates, each infusion sports specific combinations or isolations of CBD, THC, and other cannabinoids, allowing users to pick and choose products that suit their exact needs. CBD topicals, for example, are incredibly effective when applied to surface-level problems like bruises, joint aches, and headaches, and have been scientifically proven to successfully combat skin-based issues including pruritus with far broader implications.
CBD oil products can be somewhat expensive, which may be a barrier for individuals seeking treatment or relief from different conditions and disorders. cbdMD is a notable exception as far as price-point is concerned. cbdMD offers it’s premium, non-THC oils at a large variety of concentrations (300mg-5,000mg) as well as sizes (30mL and 60mL) . These oils are priced at $29.99 for 300mg oils and $99.99 for 1,500mg oils; these price-points are significantly below average.
These states are Idaho, Kansas, Nebraska and South Dakota. Now, even though marijuana-derived CBD is legal in these states, the laws are still unclear, so there are still businesses selling CBD, and patients using CBD in these states. We totally believe in the benefits CBD offers and support the CBD movement, but if you are in one of these states, be cautious and careful when considering using CBD products.
Buying online is less reliable still because there’s no regulation or standardization. What you see on the label may not be what you are getting. A 2017 study in JAMA found that of the 84 CBD products researchers bought online, 43% had more CBD than indicated, while 26% had less, and some had unexpected THC. “There’s a 75% chance of getting a product where the CBD is mislabeled,” says Marcu, one of the study’s coauthors.
The key is to effectively gauge exactly how much CBD oil it takes to start managing your pain. If you start off right away with a maximum dose of a 600 mg tincture, you will have no idea how much of the product it actually took to treat your condition, and how much you wasted (this is also important because you do not want to exceed dosage and end up developing a tolerance to the active cannabinoids).
In a report published in Pediatric Dermatology in 2018, scientists reported three cases of topical CBD (applied as an oil, cream, and spray) use in children with a rare, blistering skin condition known as epidermolysis bullosa. Applied by their parents, all three people reported faster wound healing, less blisters, and improvement of pain. One person was able to completely wean off oral opioid analgesic pain medication. There were no adverse effects reported.
The list includes marijuana (undifferentiated by strain) and heroin. (While the federal government oversees marijuana research, marijuana use is regulated, in part, by state laws.) As a result, scientists who study the compound must follow a host of restrictive rules. Last year, responding to a request from several governors to change marijuana’s designation, the Drug Enforcement Administration announced that all cannabis would remain a Schedule 1 drug.
The rosemary acts as a natural antioxidant preservative. It also supplies terpenoids, including camphene, pinene, and limonene, that support a healthy inflammatory response and promote relaxation.* Hops is a very close cousin of hemp and many of the compounds in hops are complementary to those in hemp. The hops in Hemp Oil + provides a source of the terpenoids humulon and lupulon that are synergistic with the phytocannabinoids in support of the ECS.*

A limited number of studies have examined the effects of cannabis smoking on the respiratory system.[88] Chronic heavy marijuana smoking is associated with coughing, production of sputum, wheezing, and other symptoms of chronic bronchitis.[68] The available evidence does not support a causal relationship between cannabis use and chronic obstructive pulmonary disease.[89] Short-term use of cannabis is associated with bronchodilation.[90] Other side effects of cannabis use include cannabinoid hyperemesis syndrome.[91]
I recommend CBD International to everyone I know who is fighting cancer including the Hospice team taking care of my daughter. All the different nurses always ask, they have many patients asking. If I can save anyone the three months it took me to find you, that time saved could save a life. When you find yourself in a situation like a cancer diagnosis, you are searching for something to help, you really don't know what you are getting. My visits to the medical marijuana shops in Southern California left me frustrated, they are not knowledgeable and kept steering me to edibles and hash oil and trying to find the correct treatment was for me, about the only thing I could do for my daughter that might help her and the only thing she was willing to try. From the very first contact on your website, to the questionnaire to all correspondence, so timely and the integrity and kindness you and your company have shown me, I can't praise you enough. You guys are the real deal.

The important thing is that you have to be SUPER careful when selecting CBD oils. Since the cannabis industry is not FDA-regulated, there have been dozens and dozens of companies trying to get away with selling very low quality (and even potentially toxic), “snake oils” that have been extracted using harsh chemical solvents like butane and hexane. Make sure you stay away from cheap products like these, as they could damage your health.
Cannabis has been around for thousands of years and is believed to have originated in South or Central Asia. The two main species of cannabis are Cannabis sativa and Cannabis indica. Both Cannabis sativa and indica contain varying amounts of psychoactive and nonpsychoactive components. Cannabis sativa is more commonly known for its stimulatory, mental effects while Cannabis indica is more known for its relaxing, body-calming effects.
Put simply, “indica” strains are those associated with a strong body-high, feelings of sedation and relaxation. For this reason, indicas are often thought of as the “heavier” strains of cannabis, offering stronger highs that impact the whole body. They’re popular among marijuana users as pain relieving and sleep-inducing strains. Indicas are especially popular among medical cannabis patients.
     Marijuana oil has been a hot topic over the last few years as many states pass medical Marijuana programs and more and more reports come filtering out of them regarding the therapeutic potentials offered by various extracts featuring high levels of Cannabinoids such as CBD (Cannabidiol), one of the main active substances contained within Cannabis. Dramatic cases featured on such noteworthy TV shows as the Dr. Sanjay Gupta CNN specials that first brought strains such as Charlotte's Web into the national spotlight have done much to raise public awareness of CBD.

However, like we just mentioned CBD oil for pain management that has been sourced from industrial hemp grown under the farm bill is in fact legal to buy and sell. The best CBD oil brands that we cover here on this site, claim to extract their concentrates from U.S.-based industrial hemp supplies, which if true, are 100% legal since they contain negligible amounts of THC.
If medical marijuana is illegal in a given state, THC levels determine whether a CBD product is illicit or not. In most places, the limit is extremely low. We’re talking under 1 percent THC, with some states opting for a cap as low as 0.3 percent. In this case, the only source that would work is hemp, and CBD products will, therefore, be hemp-derived.
In late 2017, researchers with the University of Guelph in Canada published the first-ever study to document the ideal growing conditions for cannabis. Using liquid organic fertilizer with a PKN ratio of 1.3P–1.7K-4.0N, the experiment tested five increasing rates of fertilization. They also tested two coir-based soil-less growing media, or “substrates.”
CBD oil is also used by some people who have cancer. A few studies in mice have shown a reduction of cancerous tumors. But most human studies have involved research into the role of CBD oil in managing pain related to cancer and cancer treatment. The National Cancer Institute (NCI) has pointed to CBD as a possible option for relieving symptoms caused by chemotherapy.

Most human studies of CBD have been done on people who have seizures, and the FDA recently approved the first CBD-based drug, Epidiolex, for rare forms of epilepsy. Clinical trials for other conditions are promising, but tiny. In one Brazilian study published in 2011 of people with generalized social anxiety disorder, for example, taking a 600-mg dose of CBD (higher than a typical dose from a tincture) lessened discomfort more than a placebo, but only a dozen people were given the pill.

Hemp being federally legal would be huge for the CBD industry, as CBD oil made from hemp extract (a plant that has very low amounts of THC) would be legal. A new, more available form of CBD would also allow for more research on the subject of cannabidiol, and perhaps the entire marijuana plant. More research brings the potential of coming closer to full legalization.
In making the two previous determinations about THC, why did FDA conclude that THC is an active ingredient in a drug product that has been approved under section 505 of the FD&C Act? In making the two previous determinations about CBD, why did FDA determine that substantial clinical investigations have been authorized for and/or instituted, and that the existence of such investigations has been made public?

A. No. Under section 301(ll) of the FD&C Act, it is prohibited to introduce or deliver for introduction into interstate commerce any food (including any animal food or feed) to which has been added a substance which is an active ingredient in a drug product that has been approved under 21 U.S.C. § 355 (section 505 of the Act) or a drug for which substantial clinical investigations have been instituted and for which the existence of such investigations has been made public. There are exceptions, including when the drug was marketed in food before the drug was approved or before the substantial clinical investigations involving the drug had been instituted or, in the case of animal feed, that the drug is a new animal drug approved for use in feed and used according to the approved labeling. However, based on available evidence, FDA has concluded that none of these is the case for THC or CBD. FDA has therefore concluded that it is a prohibited act to introduce or deliver for introduction into interstate commerce any food (including any animal food or feed) to which THC or CBD has been added. FDA is not aware of any evidence that would call into question these conclusions. Interested parties may present the agency with any evidence that they think has bearing on this issue. Our continuing review of information that has been submitted thus far has not called our conclusions into question.
The endocannabinoid system is tonically active in control of pain, as demonstrated by the ability of SR141716A (rimonabant), a CB1 antagonist, to produce hyperalgesia upon administration to mice (Richardson et al 1997). As mentioned above, the ECS is active throughout the neuraxis, including integrative functions in the periacqueductal gray (Walker et al 1999a; Walker et al 1999b), and in the ventroposterolateral nucleus of the thalamus, in which cannabinoids proved to be 10-fold more potent than morphine in wide dynamic range neurons mediating pain (Martin et al 1996). The ECS also mediates central stress-induced analgesia (Hohmann et al 2005), and is active in nociceptive spinal areas (Hohmann et al 1995; Richardson et al 1998a) including mechanisms of wind-up (Strangman and Walker 1999) and N-methyl-D-aspartate (NMDA) receptors (Richardson et al 1998b). It was recently demonstrated that cannabinoid agonists suppress the maintenance of vincristine-induced allodynia through activation of CB1 and CB2 receptors in the spinal cord (Rahn et al 2007). The ECS is also active peripherally (Richardson et al 1998c) where CB1 stimulation reduces pain, inflammation and hyperalgesia. These mechanisms were also proven to include mediation of contact dermatitis via CB1 and CB2 with benefits of THC noted systemically and locally on inflammation and itch (Karsak et al 2007). Recent experiments in mice have even suggested the paramount importance of peripheral over central CB1 receptors in nociception of pain (Agarwal et al 2007)
