Cannabis, also referred to as marijuana, has been an integral part of human civilizations for millennia. Both as a medicine and as a recreational substance, cannabis is the most popular illicit drug in the world. Today, the legal landscape that has prohibited marijuana for much of the twentieth century is giving way to decriminalization and full legalization. Legal, commercial cannabis businesses are already making an enormous economic impact.
In 1924, Russian botanist D.E. Janichevsky concluded that ruderal Cannabis in central Russia is either a variety of C. sativa or a separate species, and proposed C. sativa L. var. ruderalis Janisch, and Cannabis ruderalis Janisch, as alternative names.[48] In 1929, renowned plant explorer Nikolai Vavilov assigned wild or feral populations of Cannabis in Afghanistan to C. indica Lam. var. kafiristanica Vav., and ruderal populations in Europe to C. sativa L. var. spontanea Vav.[53][62] In 1940, Russian botanists Serebriakova and Sizov proposed a complex classification in which they also recognized C. sativa and C. indica as separate species. Within C. sativa they recognized two subspecies: C. sativa L. subsp. culta Serebr. (consisting of cultivated plants), and C. sativa L. subsp. spontanea (Vav.) Serebr. (consisting of wild or feral plants). Serebriakova and Sizov split the two C. sativa subspecies into 13 varieties, including four distinct groups within subspecies culta. However, they did not divide C. indica into subspecies or varieties.[48][64]

“The DEA makes it clear they don’t have to explicitly list anything as a controlled substance as long as a substance is intended for human ingestion, not approved as a drug by the (US Food and Drug Administration), or is structurally or pharmacologically similar to another controlled substance,” he told Leafly. “This DEA rulemaking change doesn’t make it any more illegal” than it previously was. The new rule “was an administrative change,” Armentano added. “It has nothing to do with law enforcement.”
“I just felt good,” he adds. “But I wasn’t high at all.” Joliat’s anecdotal experience with CBD is a common one. Some informal polling suggests a lot of people today are at least vaguely familiar with cannabidiol, and have either used it themselves or know someone who has. But even some people who use it don’t seem to know exactly what it is or whether there’s any hard science out there to back up its benefits.
In 2014, Mississippi passed HB 1231, which creates an affirmative defense for the possession and use of CBD oil in very limited circumstances. Known as “Harper Grace's Law,” the bill only provides legal protection to patients diagnosed with a debilitating epileptic condition, and only if the CBD oil was either obtained from or tested by the National Center for Natural Products Research at the University of Mississippi and dispensed by the Department of Pharmacy Services at the University of Mississippi Medical Center.

We have been involved in Colorado's medicinal and legal cannabis industry since its inception, so we've seen the expansion from high quality medicine to social commodity. Investment dollars have rushed into various sectors of the industry and the primary focus is ROI. When people see green it's easy to get excited and focus on the numbers instead of the patients. Of all the companies we've interacted with and tested, Ambary Gardens has been the standout. Their vertically integrated Colorado-based facility is is impressive as their product line.
A. The FDA is aware that several states have either passed laws that remove state restrictions on the medical use of marijuana and its derivatives or are considering doing so. It is important to conduct medical research into the safety and effectiveness of marijuana products through adequate and well-controlled clinical trials. We welcome the opportunity to talk with states who are considering support for medical research of marijuana and its derivatives to provide information on Federal and scientific standards.

Cognitive effects of cannabis have been reviewed (Russo et al 2002; Fride and Russo 2006), but less study has occurred in therapeutic contexts. Effects of chronic heavy recreational cannabis usage on memory abate without sequelae after a few weeks of abstinence (Pope et al 2001). Studies of components of the Halstead-Reitan battery with Sativex in neuropathic pain with allodynia have revealed no changes vs placebo (Nurmikko et al 2007), and in central neuropathic pain in MS (Rog et al 2005), 4 of 5 tests showed no significant differences. While the Selective Reminding Test did not change significantly on Sativex, placebo patients displayed unexpected improvement.
For some, a sore muscle on your lower back may feel better after using a CBD patch. For others, a headache might respond well to a CBD tincture. Pain is a universal feeling, but we respond differently and our bodies react in different ways depending on our overall health. The variety of ways in which CBD is consumed allows customers to pick a method based on their specific condition and their personal preference. For example, someone with sensitive lungs who doesn’t like smoking may prefer treating their pain with CBD capsules. Someone who takes a lot of pills, in general, may enjoy the experience of vaporizing. CBD is a naturally occurring chemical compound found in the cannabis and hemp plants. It does not produce the difficult side effects that those on prescription opioids commonly experience.
I like this product. At first I didn't like it because of the Stevia. That is the reason for the four stars instead of five. But with that said , I like the product . I find it taste great and it is relaxing and helps with my anxiety and depression . I also mix it with some other CBD things and this helps to make everything last longer . 5000 mg is a big plus too . So many others are 750 or 1000 and once you get above that , the price increases dramatically . This price is good for this product. I find that if I just take the CBD oil I have without this product that the effect is not good . My mother said it helps her with the arthritis pains and she also gave a little to her dog and she felt it helped him too . Great product and I will be ordering more.
Ten US states have legalized use of recreational marijuana as of November 2018. In 2012, voters in Colorado and Washington state passed initiatives legalizing cannabis for adults 21 and older under state law. In November 2014, Oregon, Alaska, and Washington D.C also approved recreational use of marijuana. In November 2016, four more states - California, Massachusetts, Maine, and Nevada - voted in recreational marijuana. On July 1, 2018 Vermont began allowing recreational use. In 2018, Michigan voted to legalize pot for recreational use, but a measure in North Dakota failed.
And the final nail in industrial hemp’s proverbial coffin: Federal law in the United States prohibits the use of hemp leaves and flowers to make drug products. That said, isolating CBD nullifies these distinctions, rendering its source irrelevant as CBD isolate contains nothing but CBD. In this case, the differences between industrial hemp and whole-plant marijuana are far less significant.

Jackson Leyden had always been a healthy kid; he practiced taekwondo, and he played lacrosse and baseball. But in 2011, a few months after his eighth birthday, he began having seizures several times a day. Many were brief, a half-minute of staring into space, but he also had severe episodes in which he would collapse, sometimes injuring himself. Over the next two years, he was hospitalized about 50 times, and he missed much of fourth and fifth grade.

The cost of treatment varies: Depending on the dispensary and the dosage, it can range from around $100 a month to more than $1,000. Despite the cost, which is not covered by insurance, CBD medicines are drawing great interest for children with severe, intractable epilepsy. California and Colorado, which were among the first states to legalize medical marijuana, have become hot spots for such patients. Before other states legalized medicinal CBD use, some families moved to these states so they could have access to the compound.

Outside of those four states, consumers must put their trust in the manufacturer. Sometimes that’s warranted, and sometimes it’s not. In 2016 and 2016, the FDA ran tests on several CBD products and found that many of the products had far less CBD than advertised, and in some cases none at all. You can find those test results here for 2015, and here for 2016. (These FDA tests were done as a one-off project. CBD products are not approved by the FDA for the prevention, mitigation, or treatment of any disease or condition.)


In December 2012, the U.S. state of Washington became the first state to officially legalize cannabis in a state law (Washington Initiative 502) (but still illegal by federal law),[226] with the state of Colorado following close behind (Colorado Amendment 64).[227] On January 1, 2013, the first marijuana "club" for private marijuana smoking (no buying or selling, however) was allowed for the first time in Colorado.[228] The California Supreme Court decided in May 2013 that local governments can ban medical marijuana dispensaries despite a state law in California that permits the use of cannabis for medical purposes. At least 180 cities across California have enacted bans in recent years.[229]
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.
Final thoughts: Hemp oil and hemp derived CBD oil is legal in all fifty states, but there certainly is a stigma to it. Because of that it can be very hard to find reliable information to educate yourself with. This is a great dietary supplement and may help decrease inflammation, improve skin, help with mild pain, etc. If you have severe pain, hemp derived CBD oil may be what you need.
This is because California also taxes the crops before they are even sold. Other states such as Alaska and Colorado sit between 10%-20% per sale. In some cases, California can have taxes as high as 80% if you include some Federal Taxes. What this means is that the margin of profits are so small, that it almost becomes impossible to operate a legitimate cannabis business according to their rules.
In 1972, the Dutch government divided drugs into more- and less-dangerous categories, with cannabis being in the lesser category. Accordingly, possession of 30 grams or less was made a misdemeanor.[213] Cannabis has been available for recreational use in coffee shops since 1976.[214] Cannabis products are only sold openly in certain local "coffeeshops" and possession of up to 5 grams for personal use is decriminalised, however: the police may still confiscate it, which often happens in car checks near the border. Other types of sales and transportation are not permitted, although the general approach toward cannabis was lenient even before official decriminalisation.[215][216][217]

A 2012 study reported that, “systemic and intrathecal administration of cannabidiol (CBD), a major nonpsychoactive component of marijuana, and its modified derivatives significantly suppress chronic inflammatory and neuropathic pain without causing apparent analgesic tolerance…These cannabinoids may represent a novel class of therapeutic agents for the treatment of chronic pain and other diseases…” 

CBD oil is extracted from the industrial hemp plant, Cannabis Sativa. The seeds of the hemp plant are pressed until the oils are released. This is what makes cannabidiol different from and less psychoactive than THC, which is extracted from the marijuana plant, Cannabis Indica. The industrial hemp oil has traces of THC in it, about 3% in potency, not sufficient in causing a ‘high’. Despite its non-addictive nature, CBD oil may require a medical prescription for legal acquisition in some provinces.
Though very rare, some people report side effects when using hemp oil. These side effects include low blood pressure, dry mouth, slowed thoughts, lightheadedness, and sedation. Animal studies have not found any toxicity issues with using CBD. In fact, a study in 2006 found that "the available clinical data suggest that CBD can be safely administered over a wide dose range." As always, because there aren't long-term safety studies, you should always check with your health care provider before starting hemp oil.
Cannabis is known to aid relaxation, which makes it a popular treatment for social anxiety – however due to the THC content in cannabis, it can actually trigger more intense feelings of paranoia and anxiety. CBD on the other hand, has the opposite effect, helping to calm down the nerves and keep you grounded. Anxiety disorders and other feelings of irrational fear can be overwhelming especially if you find yourself in unfamiliar environments, however CBD can be used effectively to generate calmness and peacefulness, and without the addictive component of anti-anxiety medication like Benzos or Xanax. 

Unlike other CBD oils, PureKana really does excel in CBD oil extractions due to their unique CO2 extraction process which provides a near 99% pure CBD oil. PureKana Natural CBD Oil is an unflavored, dietary and nutritional supplement for increased health and vitality. It is extremely effective in treating chronic pain, inflammation, swelling, anxiety and sleep disorders.
Strains such as Charlotte's Web, that started out being classified as "marijuana" strains, have now been able to be reclassified as Hemp strains, due to the meeting of the .3% THC threshold. This is an important designation, as breeders are now breeding Cannabis strains down to acceptable THC levels, while still offering a plant that carries all of the other combinations of naturally occurring Cannabinoids, which provide a synergistic effect when taken together along with the plants given Terpenoid and Flavanoid profiles.
Hey Justin, after further research and consultation it looks like the law is still a little unclear. According to NWTimes, CBD is now legal; however the law further clarifies that the CBD must contain certification that it contains less than 0.3% THC and is derived from industrial-hemp and not marijuana. That said, CBD from industrial hemp is legal for recreational usage, while CBD derived from marijuana is still viewed under the same laws as marijuana.… Read more »
     2014 saw a flurry of interest in Cannabidiol in particular, with a slew of states successfully passing CBD only legislation after mounting pressure from many numbers of families with children suffering from intractable Epilepsy resulted in the fast tracking of Cannabidiol laws in more than 10 U.S. states. The Cannabidiol issue is proving to be quite popular politically as it allows politicians to get behind the "won't get you high" side of the CBD story while temporarily dancing around the looming issues of future medical marijuana programs that are pending or have been proposed in many of these states, as well as the national movement towards approval for medicinal and recreational use on a large scale.

Oral dronabinol (THC) is marketed in synthetic form as Marinol® (Solvay Pharmaceuticals) in various countries, and was approved in the USA for nausea associated with chemotherapy in 1985, and in 1992 for appetite stimulation in HIV/AIDS. Oral dronabinol’s expense, variability of action, and attendant intoxication and dysphoria have limited its adoption by clinicians (Calhoun et al 1998). Two open label studies in France of oral dronabinol for chronic neuropathic pain in 7 subjects (Clermont-Gnamien et al 2002) and 8 subjects (Attal et al 2004), respectively, failed to show significant benefit on pain or other parameters, and showed adverse event frequently requiring discontinuation with doses averaging 15–16.6 mg THC. Dronabinol did demonstrate positive results in a clinical trial of multiple sclerosis pain in two measures (Svendsen et al 2004), but negative results in post-operative pain (Buggy et al 2003) (Table 1). Another uncontrolled case report in three subjects noted relief of intractable pruritus associated with cholestatic jaundice employing oral dronabinol (Neff et al 2002). Some authors have noted patient preference for whole cannabis preparations over oral THC (Joy et al 1999), and the contribution of other components beyond THC to therapeutic benefits (McPartland and Russo 2001). Inhaled THC leads to peak plasma concentration within 3–10 minutes, followed by a rapid fall while levels of intoxication are still rising, and with systemic bioavailability of 10%–35% (Grotenhermen 2004). THC absorption orally is slow and erratic with peak serum levels in 45–120 minutes or longer. Systemic bioavailability is also quite low due to rapid hepatic metabolism on first pass to 11-hydroxy-THC. A rectal suppository of THC-hemisuccinate is under investigation (Broom et al 2001), as are transdermal delivery techniques (Challapalli and Stinchcomb 2002). The terminal half-life of THC is quite prolonged due to storage in body lipids (Grotenhermen 2004).
Some jurisdictions use free voluntary treatment programs and/or mandatory treatment programs for frequent known users. Simple possession can carry long prison terms in some countries, particularly in East Asia, where the sale of cannabis may lead to a sentence of life in prison or even execution. Political parties, non-profit organizations, and causes based on the legalization of medical cannabis and/or legalizing the plant entirely (with some restrictions) have emerged in such countries as China and Thailand.[224][225]
Can cannabis help treat psoriasis? The active cannabinoids in cannabis may be an effective treatment for psoriasis. Research shows that they offer potential health benefits that could relieve the symptoms of psoriasis. They may be able to reduce inflammation and itching, control pain, and even heal wounds.

Some states only allow for products infused with CBD, some only allow for high-CBD and low-THC products, while others allow both THC and CBD. To further confuse the American citizenry, some states permit patients the use of CBD, but require that they travel to another state to purchase it. To make sense of this confounding patchwork and to learn about each individual state’s CBD laws, read the Weedmaps Laws and Regulations page.
If you are living with chronic pain, hemp offers you hope. CBD can be purchased online or over the counter in many forms in every state in the U.S., and many places around the world. The good news is CBD has a very broad safety profile, and you should feel comfortable trying it. Dosing is going to be a key, and we’ll discuss that in a later column. Taking too much won’t harm you, but it might not help you either. Please be sure to talk to your physician about CBD. In my next column, I will offer some tips for having this conversation, particularly if you feel awkward about cannabis or hemp, or suspect your doctor might react badly to your interest.
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]
Cannabinoids are divided into three groups. The first are naturally occurring 21-carbon terpenophenolic compounds found to date solely in plants of the Cannabis genus, currently termed phytocannabinoids (Pate 1994). The best known analgesic of these is Δ9-tetrahydrocannabinol (henceforth, THC)(Figure 1), first isolated and synthesized in 1964 (Gaoni and Mechoulam 1964). In plant preparations and whole extracts, its activity is complemented by other “minor” phytocannabinoids such as cannabidiol (CBD) (Figure 1), cannabis terpenoids and flavonoids, as will be discussed subsequently.

Endocannabinoids are organically produced by the human body, generated by the endocannabinoid system. Endocannabinoids have been found to help in the regulation of sleep, pain and the responses of the immune system. Cannabis scientists have been investigating the role of physiological cannabinoids in tissue recovery and disease. It is fascinating that the endocannabinoids activate the same receptors as the psychoactive THC.
Given its name, you might assume THCV shares psychoactive powers with its potent counterpart, THC. In reality, this cannabinoid is more like a cross between CBD and THC. From the former, it takes its modulating powers. Acting like THC “lite,” THCV like CBD can dampen the effects of a strong high. Yet at higher doses, THCV kicks into a psychoactive stimulant in its own right.
Cannabis was known to the ancient Assyrians, who discovered its psychoactive properties through the Iranians.[196] Using it in some religious ceremonies, they called it qunubu (meaning "way to produce smoke"), a probable origin of the modern word "cannabis".[197] The Iranians also introduced cannabis to the Scythians, Thracians and Dacians, whose shamans (the kapnobatai—"those who walk on smoke/clouds") burned cannabis flowers to induce trance.[198] The plant was used in China before 2800 BC, and found therapeutic use in India by 1000 BC, where it was used in food and drink, including bhang.[199][200]
Hemp oil is comprised of 25 percent protein, says Dr. Andrew Weil, the program director for the Arizona Center for Integrative Medicine, which is recognized by the Arizona Board of Regents. This high-quality protein provides amino acids in ratios similar to the protein in meats and eggs. The structure of hemp oil proteins makes them easily digestible. Compared to other oils, hemp oil provides the protein and amino acids the body needs without adding unnecessary calories.
Before purchasing any CBD product in these states (aside from the 8 mentioned above) you must have a medical prescription issued by a certified medical doctor. Each state has a particular concentration of THC it allows to be present in a CBD product, with the percentage ranging from 0.3% — 8%. (See details in table 1.1 below). Even though the legal situation seems to be shifting in a positive direction, if you are in any of these states, it is very important to be aware of the state’s laws towards CBD.
After ignoring the CBD oil on the shelves of health food stores for months; the state excise police in Indiana began raiding stores recently for CBD oil. According to the State Excise Police, CBD is considered the same as marijuana in the state of Indiana. Even thought that makes zero sense since it does not have any psychoactive chemicals in it at all (or so little as to not count). Thus it is idiocy but must be coming from the top as the Governor is the head cheese they would not be raiding unless he had given the OK. So it is stupid and a waste of taxpayer money. Hitting the health food stores hard; and people will just pay a little more to order it online. CBD oil works for a variety of health conditions. It is big pharma that is trying to keep it off the shelves. But in the end they will lose this one.
There is a lot of excitement about hemp oil these days. There is also a lot of confusion. While many people have heard of hemp oil, they aren’t exactly sure what it does. Or whether or not it contains THC, the psychoactive ingredient in marijuana. Will hemp oil make you “high”? If you use a hemp oil supplement are you breaking any laws? The following are answers to some of the most frequently asked questions about hemp oil.
More recent studies have focused on the mechanisms behind the schizophrenia–cannabis interaction. Epstein and Kumra (2014) tested the effect of cannabis on executive control of attention and cognitive function by comparing scores on the Attention Network Test among people with early-onset schizophrenia (EOS) and cannabis use disorder, only EOS, only cannabis use disorder, and controls. They found that the first group in particular had less efficient executive control of attention compared with those who had only EOS. They also found a smaller right caudal anterior cingulate cortex in subjects with EOS and cannabis use disorder. However, it is presently unclear whether this means that the smaller cortex surface leads to deficits in self-regulation and heavy cannabis use or if the direction of causation is in the opposite direction. More recent studies have suggested gene–environment correlation between cannabis use and schizophrenia in that the increased risk of schizophrenia after heavy and consistent cannabis use may be moderated by a shared gene that may explain part of the association (Power et al., 2014).
Several studies have demonstrated the therapeutic effects of cannabinoids for nausea and vomiting in the advanced stages of illnesses such as cancer and AIDS. Dronabinol (tetrahydrocannabinol) has been available by prescription for more than a decade in the USA. Other therapeutic uses of cannabinoids are being demonstrated by controlled studies, including treatment of asthma and glaucoma, as an antidepressant, appetite stimulant, anticonvulsant and anti-spasmodic, research in this area should continue. For example, more basic research on the central and peripheral mechanisms of the effects of cannabinoids on gastrointestinal function may improve the ability to alleviate nausea and emesis. More research is needed on the basic neuropharmacology of THC and other cannabinoids so that better therapeutic agents can be found.
Cannabis is known to aid relaxation, which makes it a popular treatment for social anxiety – however due to the THC content in cannabis, it can actually trigger more intense feelings of paranoia and anxiety. CBD on the other hand, has the opposite effect, helping to calm down the nerves and keep you grounded. Anxiety disorders and other feelings of irrational fear can be overwhelming especially if you find yourself in unfamiliar environments, however CBD can be used effectively to generate calmness and peacefulness, and without the addictive component of anti-anxiety medication like Benzos or Xanax.

To decide between these hypotheses, we need evidence that cannabis use preceded the psychosis; that plausible alternative explanations based on confounding can be excluded (Hall, 1987). The best evidence for answering these questions comes from longitudinal population-based studies that have assessed cannabis use before the onset of psychotic symptoms, followed the cohort over a substantial period and used statistical methods to assess the contribution of a variety of factors other than cannabis use that may explain the relationship (Macleod et al., 2004).


Hemp is often mistaken for its cannabis cousin, marijuana, even though smoking an entire garbage bag of hemp would not produce an altered state of consciousness, as hemp contains low levels of THC. Confusion between hemp oil and marijuana oil has spiked recently, as states have passed medical marijuana laws that allow for the use of strains of marijuana that are low in THC and high in CBD. Consumers often confuse hemp oil with CBD oil because both are low in THC and contain CBD.

In theory, getting a false positive on a drug test from CBD oil should be relatively impossible from pure CBD oil containing less than .3 percent THC. However, because CBD oil is not very well regulated, there is no guarantee that a product contains pure CBD oil, or that its concentration is at a safe or effective level. It is best to use utmost caution and do your research when purchasing a quality CBD oil product to ensure its purity, especially if you need to undergo drug screenings.
A a bipartisan group of lawmakers sent a letter to the FDA last week, urging immediate action on the matter. A series of recent actions in New York City, Maine and Ohio cracking down on the sale of CBD foods and drinks have “spurred a tremendous amount of confusion among product manufacturers, hemp farmers, and consumers of these products,” said the letter, as reported by Weedmaps, an information community website for businesses and consumers.
The ECS is responsible for setting the baseline activity levels of our immune system and nervous system, which then work to maintain our health. When the ECS falls out of whack, the systems that are regulated by it can begin to malfunction. CBD promotes the normal health and function of the endocannabinoid system, so it’s possible that CBD can help to alleviate the symptoms of conditions that are caused by dysfunction of the endocannabinoid system.

Of course, though, they offer less potent oils than that, with a product lineup that ranges from 300 mg CBD per bottle to 4,000 mg. Naturally the 4,000 mg option is the most expensive (this is the one that provides the “bomb” 60 mg dose), as it currently sells for $299. For long-term pain and anxiety relief, though, it may be well worth it if it is effective for you and helps replace your regular meds.
Some studies state that while there is no proof for the gateway hypothesis,[263] young cannabis users should still be considered as a risk group for intervention programs.[264] Other findings indicate that hard drug users are likely to be poly-drug users, and that interventions must address the use of multiple drugs instead of a single hard drug.[265] Almost two-thirds of the poly drug users in the "2009/10 Scottish Crime and Justice Survey" used cannabis.[266]

CBD was first discovered in 1940 by Roger Adams, a prominent organic chemist at the University of Illinois. Shortly thereafter, other scientists began testing isolated cannabinoids on lab animals; notably, Walter S. Loewe ran trials on mice and rabbits with the cannabinoids THC, CBD and CBN. He found that CBD produced no observable effects in the animals’ behavior while THC caused, what he called, a “central excitant action” in rabbits. Despite science’s movement forward, scientists were completely unaware of the cannabinoids’ chemical structure, so no one could tell which specific compound resulted in which effect.
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.
In a SAFEX study of Phase III double-blind RCT in 160 subjects with various symptoms of MS (Wade et al 2004), 137 patients elected to continue on Sativex after the initial study (Wade et al 2006). Rapid declines were noted in the first twelve weeks in pain VAS (N = 47) with slower sustained improvements for more than one year. During that time, there was no escalation of dose indicating an absence of tolerance to the preparation. Similarly, no withdrawal effects were noted in a subset of patients who voluntarily stopped the medicine abruptly. Upon resumption, benefits resumed at the prior established dosages.

While most supplements have a single recommended dose, CBD is different. The amount of CBD you take depends on your doctor’s recommendations and your own research into how CBD will work for your unique needs. In general, it’s smart to start with a medium dose of CBD. This way, you can increase or decrease the dose as needed. In addition, it’s recommended to start with one half ML (half a dropper) of CBD oil, because you can always take more if needed.
