Concerns are frequently noted with new drug-drug interactions, but few have resulted in Sativex RCTs despite its adjunctive use with opiates, many other psychoactive analgesic, antidepressant and anticonvulsant drugs (Russo 2006a), possibly due to CBD ability to counteract sedative effects of THC (Nicholson et al 2004). No effects of THC extract, CBD extract or Sativex were observed in a study of effects on the hepatic cytochrome P450 complex (Stott et al 2005b). On additional study, at 314 ng/ml cannabinoid concentration, Sativex and components produced no significant induction on human CYP450 (Stott et al 2007). Thus, Sativex should be safe to use in conjunction with other drugs metabolized via this pathway.
Some users speculate about appropriate dosages or methods of application—including whether or not a small amount of THC boosts CBD’s effects, or whether different methods of administration lead to quicker or more significant effects. Some CBD producers also claim that it has a cumulative effect, and so needs to be used regularly to produce a benefit. But Grant says it’s tough to say at this point exactly how people should (or shouldn’t) be using CBD.
The phytocannabinoid cannabidiol (CBD), is a non-intoxicating molecule that results from the heating, or decarboxylation, of cannabidiolic acid, or CBDA. As popular as CBD has become in both the cannabis community and mainstream consumerism, its natural precursor, CBDA, is one of 114 unique cannabinoids found in cannabis. In most cultivars, or cultivated varieties of cannabis, CBD ranks low on the expression chart; there often isn’t much. However, following a explosive discovery in 2009 — it was noted that a handful of strains are rich in CBD over THC. Droves of CBD-rich cultivars began cropping up all across the US, resulting in a marked uptick in CBD availability across the states.
In a study conducted by researchers from the Lautenberg Center, researchers discovered that CBD was more effective for treating inflammation and pain when used with other cannabis plant compounds derived from a full spectrum product over a CBD isolate product alone. This is one reason that full spectrum products (those containing THC) are popular.  
The reason so many people are interested in cannabis products that don’t make them high, proponents say, is that CBD helps with everything from pain and nausea to rheumatoid arthritis, cancer, Crohn’s disease, and dementia. CBD is anti-inflammatory, anti-anxiety, antibacterial, immunosuppressive, and more, says Joseph Cohen, D.O., a cannabis doctor in Boulder, CO.
In a study whose findings have not yet been published, he and a colleague, Daniel Friedman, found that patients receiving CBD in addition to their usual medicines had 39 percent fewer convulsive seizures than patients who remained on their normal drug regimen. Given that the study included only the most treatment-resistant patients, this is an “excellent response,” Devinsky says.
Of course, hemp oils are not marijuana oils, but this illustrates some of the complications arising from various states legal marijuana programs and medical marijuana programs in 2018.  Some states are allowing for the sales of CBD oils that contain zero % THC, while .03% is the widely accepted standard for industrial hemp classification in other countries and U.S. states. While I am unaware of anyone being prosecuted for simple possession of hemp based CBD oil in the United States in the last 4 years, one should consult their current state laws when purchasing hemp based CBD oils online.  Officials in Tennessee moved recently in February 2018 to shutter over 20 local tobacco and smoke type shops, that were selling CBD gummies among other products, alleging them to be derived from "marijuana". (These charges have all been dropped)  Interestingly, Tennessee is also chief among the U.S. states who are currently growing hemp for CBD extraction, under the provisions of the 2014 Farm Bill.
Extensive studies have demonstrated that many common illnesses are related to deficiencies or imbalances of specific fatty acids in the body. Symptoms are often related to a lack of Omega 3 and Omega 6 fatty acids and their derivatives, the postaglandins. Most people eating a healthful diet, one that includes a balanced ratio of essential fatty acids, also have healthy skin and a strong immune system. Yet some individuals may experience shortages in specific fatty acids or their metabolites due to dysfunctional enzyme systems or other inhibitions in their metabolic pathways caused by genetic, immune-system-related, or even environmental factors. It has been proven in several clinical studies that dietary supplementation with essential fatty acids or their metabolites (such as GLA) will often prevent or even cure these illnesses. Since hemp seed oil contains both essential fatty acids in a desirable balance while also providing two of the essential fatty acid metabolites, it is a good resource for the prevention and treatment of certain illnesses.
Sativex® (GW Pharmaceuticals) is an oromucosal whole cannabis-based spray combining a CB1 partial agonist (THC) with a cannabinoid system modulator (CBD), minor cannabinoids and terpenoids plus ethanol and propylene glycol excipients and peppermint flavoring (McPartland and Russo 2001; Russo and Guy 2006). It was approved by Health Canada in June 2005 for prescription for central neuropathic pain in multiple sclerosis, and in August 2007, it was additionally approved for treatment of cancer pain unresponsive to optimized opioid therapy. Sativex is a highly standardized pharmaceutical product derived from two Cannabis sativa chemovars following Good Agricultural Practice (GAP) (de Meijer 2004), yielding Tetranabinex® (predominantly-THC extract) and Nabidiolex® (predominantly-CBD extract) in a 1:1 ratio. Each 100 μL pump-action oromucosal Sativex spray actuation provides 2.7 mg of THC and 2.5 mg of CBD. Pharmacokinetic data are available, and indicate plasma half lives of 85 minutes for THC, 130 minutes for 11-hydroxy-THC and 100 minutes for CBD (Guy and Robson 2003). Sativex effects commence in 15–40 minutes, an interval that permits symptomatic dose titration. A very favorable adverse event profile has been observed in over 2500 patient years of exposure in over 2000 experimental subjects. Patients most often ascertain an individual stable dosage within 7–10 days that provides therapeutic relief without unwanted psychotropic effects (often in the range of 8–10 sprays per day). In all RCTs, Sativex was adjunctively added to optimal drug regimens in subjects with intractable symptoms, those often termed “untreatable.” Sativex is also available by named patient prescription in the UK and the Catalonia region of Spain. An Investigational New Drug (IND) application to study Sativex in advanced clinical trials in the USA was approved by the FDA in January 2006 in patients with intractable cancer pain.

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]
Now, with the passing of the new 2018 Farm Bill, hemp and hemp-derived products have been officially removed from the purview of the Controlled Substances Act, such that they are no longer subject to Schedule I status. Meaning that so long as CBD is extracted from hemp and completely pure (without any THC — something the DEA doubts is possible) and grown by licensed farmers in accordance with state and federal regulations, it is legal as a hemp product.
Cannabidiol is insoluble in water but soluble in organic solvents such as pentane. At room temperature, it is a colorless crystalline solid.[43] In strongly basic media and the presence of air, it is oxidized to a quinone.[44] Under acidic conditions it cyclizes to THC,[45] which also occurs during pyrolysis (smoking).[46] The synthesis of cannabidiol has been accomplished by several research groups.[47][48][49]
Third-party testing: Once a CBD oil is manufactured, CBD oil companies will often submit their products for third-party tests, which are conducted by non-company personnel to ensure the product is safe for public consumption and meets quality standards.CBD oils should always be accompanied with information about third-party tests; best practice is to avoid oils that do not supply these details.
Researchers think that CBD interacts with receptors in your brain and immune system. Receptors are tiny proteins attached to your cells that receive chemical signals from different stimuli and help your cells respond. This creates anti-inflammatory and painkilling effects that help with pain management. This means that CBD oil may benefit people with chronic pain, such as chronic back pain.
This type of Hemp oil should not be confused with well known nutritional products that have been sold for some time now such as Hemp seed oil, which are sold for their high nutritional value and typically contain very little if any Cannabidiol or other Cannabinoids. These nutritional products are however, sold under the same laws that allow for Hemp based Cannabinoids to be sold legally.
While it’s true that CBD is legal in all 50 states, there are situations when it isn’t legal. The difference between legal and illegal typically depends on several important factors determined by the state in question. There is, however, one very important factor that is a crucial determinant across all states, and that is where the CBD is derived from–hemp or marijuana.
The reason so many people are interested in cannabis products that don’t make them high, proponents say, is that CBD helps with everything from pain and nausea to rheumatoid arthritis, cancer, Crohn’s disease, and dementia. CBD is anti-inflammatory, anti-anxiety, antibacterial, immunosuppressive, and more, says Joseph Cohen, D.O., a cannabis doctor in Boulder, CO.
Cannabis most likely originates from Central Asia, as archeological evidence indicates that it was already cultivated in China for food and fiber 10 000 years ago. Even in ancient Egyptian mummies, clues have been found for the use of Cannabis as food or medicine.25 In fact, Cannabis is one of the oldest known medicinal plants and is described in almost every ancient handbook on plant medicine, most commonly in the form of a tincture or a tea.26,27 Some religions were closely related with the properties of the Cannabis plant. For example, in Hindu legend, Cannabis is believed to be the favorite food of the god Shiva, because of its energizing properties. As Cannabis spread from Asia toward the West, almost every culture came into contact with this miracle plant. Nowadays, varieties of Cannabis can be found in all temperate and tropical zones, except in humid, tropical rain forests.28
Various strains of "medical marijuana" are found to have a significant variation in the ratios of CBD-to-THC, and are known to contain other non-psychotropic cannabinoids.[61] Any psychoactive marijuana, regardless of its CBD content, is derived from the flower (or bud) of the genus Cannabis. Non-psychoactive hemp (also commonly-termed industrial hemp), regardless of its CBD content, is any part of the cannabis plant, whether growing or not, containing a ∆-9 tetrahydrocannabinol concentration of no more than 0.3% on a dry-weight basis.[62] Certain standards are required for legal growing, cultivating, and producing the hemp plant. The Colorado Industrial Hemp Program registers growers of industrial hemp and samples crops to verify that the dry-weight THC concentration does not exceed 0.3%.[62]
With President Trump signing off on the Agricultural Improvement Act of 2018 (aka the 2018 Farm Bill) last month, the federal government now fully recognizes hemp as a legal agricultural product. But while many reports are claiming that this means that cannabidiol (CBD) is also legal, that’s not quite correct. With a lot of misinformation flying around, and contradictions between state and federal laws, things are admittedly somewhat confusing. Let’s try to sort things out by answering some questions about hemp, CBD, and what has recently changed in federal law.
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 »
The FDA’s refusal to allow companies to market CBD as a dietary supplement is based on the fact that federal classification as a dietary supplement requires that a substance has not been authorized for investigation as a new drug or medicine. Since Epidiolex has been studied in clinical trials by GW Pharmaceuticals going back several years now and was granted orphan drug status by the FDA in 2013, CBD cannot therefore be classified as a dietary supplement. Or so the FDA says. But cannabis companies are arguing that they started marketing CBD as a dietary supplement before there were any drug trials involving CBD, such that they should still be allowed to claim dietary supplement status for their products. Thus far however, the FDA isn’t budging on this issue.  

According to PeaceHealth, a website dedicated to providing information on an array of different supplements and medications, hemp oil can cause minor side effects in the digestive system. For example, the website suggests that hemp and hemp oil can soften the stools, often leading to diarrhea or abdominal cramping. Many times, excessive diarrhea can lead to increased weight loss or malabsorption. While further research is needed to substantiate these side effect claims, it is recommended that for individuals with a history of digestive disorders or irregular bowel movements to not take hemp oil supplements.


While medical marijuana is grown to be high in CBD for the treatment of specific ailments, the THC content can vary dramatically, sometimes getting as high as the CBD content. For an excellent example of the types of marijuana you may find in a licensed dispensary, see this Strain Book. It shows you the types of plants, the percentages of CBD and THC, and even the taste and effects of the stain.

CBD shops around Chicago have been hiring more employees to handle increased demand in recent months, and some are considering opening suburban locations. An Ohio-based company said last week that it plans to open 300 shops that sell CBD-infused beauty products at malls throughout the country this year, at least eight of which are set to open in the Chicago area by summer. Until recently, the products were sold mostly online or in vape shops.
PTSD. My husband suffers chronic PTSD from active military service. We live not far from a large Army base and though my husband served with another counties military we hear stories constantly of family breakdowns over PTSD. It’s not a easy path but I’m hoping one day to find something to stop the endless trips to the psych ward. It’s just not right that those who serve come home to no government help.

For example, most people believe that sublingual consumption results in a faster effect while applying CBD to the skin might take longer but its effects also last longer. However, other users believe that because you apply CBD cream to the skin, it absorbs faster and offers more targeted pain relief. It is important to note that most CBD creams don’t act transdermally which would mean they pass through the skin and into the bloodstream. Instead, they are absorbed into the top layer of your skin which is why they are classified as ‘topicals.’
One area where CBD is clearly helpful: the treatment of seizures associated with one form of epilepsy. A 2017 New England Journal of Medicine study found ingesting oral CBD dramatically cut down most patients’ seizure frequency—a finding that prompted the FDA to support the approval of one CBD drug for use in the treatment of some epilepsy patients.

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.

Republican Governor Eric Holcomb, with the help of Republican dominant General Assembly, passed the law on Wednesday. He signed into law Senate Enrolled Act 52 that explicitly legalizes CBD oil. This was done in response to the opinion set by Attorney General Curtis Hill. The opinion that essentially said that “Simply put, cannabidiol is a Schedule 1 controlled substance because marijuana is a Schedule 1 controlled substance,”

Results of a Phase III study (N = 177) comparing Sativex, THC-predominant extract and placebo in intractable pain due to cancer unresponsive to opiates (Johnson and Potts 2005) demonstrated that Sativex produced highly statistically significant improvements in analgesia (Table 1), while the THC-predominant extract failed to produce statistical demarcation from placebo, suggesting the presence of CBD in the Sativex preparation was crucial to attain significant pain relief.
Dispensaries: In states where marijuana is legal for recreational use, dispensaries are a common sight. They are much rarer in states with more restrictions. In states that permit the use of medical marijuana, hemp-based CBD oils do not normally require a prescription but marijuana-based oils do. Like brick-and-mortar locations, dispensaries offer more customer service. However, as noted, this may not be an option depending on the buyer’s state of residence. Also, CBD oil prices tend to be significantly higher at dispensaries.
Pure CBD hemp oil is extracted from the cannabis varieties that are naturally abundant in CBD, and low in THC. A specialized extraction process is used to yield highly concentrated CBD oil or pure cannabidiol that also contains other nutritious material such as omega-3 fatty acids, terpenes, vitamins, chlorophyll, amino acids, and other phytocannabinoids like cannabichromene (CBD), cannabigerol (CBG), cannabinol (CBN) and cannabidivarian (CBCV).
Yet another benefit of essential fatty acids is mood health. Several studies have shown that Omega 3 supplementation can improve symptoms in bipolar disorder. Others have found improvements in. This could be because essential fatty acids are critical to maintaining brain function.  Endocannabinoids are also essential for mood. The endocannabinoid system regulates the release of neurotransmitters, some of which play major roles in conditions like depression and anxiety. As mentioned previously, endocannabinoids are made from fat. Consuming extra essential fatty acids gives your body the ability to produce these lipids.
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. 

Cannabinoids can be agonists, inverse agonists or inhibitors. The agonists simply stimulate a bodily function once they adhere to their respective receptors. Inverse agonists associate themselves with the same receptors as agonists, while causing a chemical reaction opposite to the ones caused by agonists. Inhibitors simply stop a chemical reaction or response once bound to their receptors.
Discount Nutrition store operator Anthony LaBorde and owner Mona Baker discuss the CBD oil they sell at their stores in Midtown Atlanta and Acworth. Across Georgia, stores are selling cannabidiol to the public, while registered medical marijuana patients can’t legally buy low THC oil.

CBD is an extract from the cannabis plant used to help support overall wellbeing. CBD products support your complete wellbeing by working with your Endocannabinoid System (ECS). In the 1990s, the first Endocannabinoid System receptors were cloned: CB1 and CB2. CB1 receptors have an effect on the brain, and nervous system and how our bodies feel overall. For more products you can check the link bellow.

Depression? Arthritis? Inflammation contributes to pain, stiffness, and poor health over time. Many individuals opt for CBD to control inflammation. However, THC has a part to play as well. Research suggests that, in some instances, the cannabis compound can decrease the production of cytokine and chemokine compounds in the body. Cytokine and chemokines are immune compounds that trigger inflammation. Additional pre-clinical research suggests that it may be able to decrease inflammation by suppressing genes related to inflammatory response. I believe people deserve access to all parts of the cannabis plant! Together, we can spread the cannabis education not DEA lies! Just as they have done opiates! Also, it’s ridiculous to wage war between the two! Have pain patients saying medical marijuana doesn’t work etc and others saying opiates are bad. There should be access to both – whatever works for someone! I never used marijuana until forced off my opiates cold turkey in cancer recurrence left dying in stage 4 cancer pain! It stopped the pain, vomiting & 2 metastatic tumors gone confirmed via MRI. I’m not claiming it cured it but feel it slowed it down and did kill two tumors. Marijuana/Opiates – WE SHOULD HAVE A CHOICE OR BOTH IF NEEDED! Shame on our Government for all the lies and trying to turn the people against one another. I hate the DEA, CDC, FDA! Just alone at what they allow in our food – the steroids, antibiotics it is sickening! They take away opiates yet cigarettes & alcohol are legal!?!?! What kind of [edit] is that! And marijuana has never caused one death – sch 1. The alcohol/cigarette related addictions/deaths as well as cases of cancer as other terminal illness they cause! Hell we need opiates for the pain from those illnesses from their legal substances they avoid talking about if I keep it real because they sure as hell wont!
Armentano pointed to several pieces of evidence as proof that CBD has always been treated as illegal at the federal level. Congress has tried and is currently trying to pass bills to remove CBD from the Controlled Substances Act—which would be unnecessary if the compound were already legal. Further, the Controlled Substances Act itself specifies that the government has the right to control substances that are chemically similar to the ones explicitly listed.

^ A 2016 review also found a statistically significant increase in crash risk associated with marijuana use, but noted that this risk was "of low to medium magnitude."[73] The increase in risk of motor vehicle crash for cannabis use is between 2 and 3 times relative to baseline, whereas that for comparable doses of alcohol is between 6 and 15 times.[74]
President Obama’s execution of the Agricultural Act of 2014 is an integral piece to CBD oil’s legality. If a plant is deemed legal (where the determining factor is a THC level under .3%) that then makes all products made from the source material legal as well. Did you ever wonder why your hemp lotion 15-20 years ago was legal but “smoking a little weed” wasn’t? In this case, it’s all about the THC levels your plant doesn’t have.
Researchers think that CBD interacts with receptors in your brain and immune system. Receptors are tiny proteins attached to your cells that receive chemical signals from different stimuli and help your cells respond. This creates anti-inflammatory and painkilling effects that help with pain management. This means that CBD oil may benefit people with chronic pain, such as chronic back pain.
“THC”—the more-famous, high-inducing compound in cannabis—“works directly on the cannabinoid system, meaning it attaches to receptors and mimics some of our own internal endocannabinoids,” says Igor Grant, a professor and chair of psychiatry at the University of California, San Diego School of Medicine. But CBD’s interaction with the endocannabinoid system is subtler. “Normally, these endocannabinoid-signaling molecules are broken down by enzymes, and one thing CBD does is interfere with the actions of those enzymes.”
In the 1950s, the Narcotics Control Act and the Boggs Act stiffened penalties for marijuana possession, with first-time offenses requiring two to 10 year sentences and a minimum $20,000 fine, according to PBS.org. Penalties were relaxed in the 1970s, but President Ronald Reagan increased federal penalties for marijuana possession in the 1980s. On the federal level, marijuana is now regulated under the Controlled Substances Act as a schedule 1 drug, meaning the government considers it to have a high potential for abuse with no legitimate medical or therapeutic uses.
The ultimate goal of all drug-abuse treatment is to enable people to achieve lasting abstinence, but the immediate goals are to reduce drug use, improve the person's ability to function, and minimize medical and social complications. Like people with diabetes or heart disease, people in treatment for drug addiction will need to change behaviors to adopt healthier lifestyles.
Nature’s Script also sells a pet CBD tincture in 150mg, 300mg, and 1,000mg concentrations. As a general rule of thumb, low-concentration oils are a good option for smaller dogs while larger concentrations may be more suitable for larger breeds – but pet owners should always check with their vet beforehand. In addition to standard shipping, Nature’s Script offers expedited delivery for customers in the contiguous U.S.
The use of Cannabis as a mind-altering drug has been documented by archaeological finds in prehistoric societies in Eurasia and Africa.[85] The oldest written record of cannabis usage is the Greek historian Herodotus's reference to the central Eurasian Scythians taking cannabis steam baths.[86] His (c. 440 BCE) Histories records, "The Scythians, as I said, take some of this hemp-seed [presumably, flowers], and, creeping under the felt coverings, throw it upon the red-hot stones; immediately it smokes, and gives out such a vapour as no Grecian vapour-bath can exceed; the Scyths, delighted, shout for joy."[87] Classical Greeks and Romans were using cannabis, while in the Middle East, use spread throughout the Islamic empire to North Africa. In 1545, cannabis spread to the western hemisphere where Spaniards imported it to Chile for its use as fiber. In North America, cannabis, in the form of hemp, was grown for use in rope, clothing and paper.[88][89][90][91]
Consumers report using CBD for a huge variety of health and wellness reasons, but a lot more research is needed to determine which symptoms and ailments it works best for. Currently, there are more than 40 clinical trials enrolling patients to examine the effectiveness of CBD for a variety of diseases, including substance use disorder, chronic pain, post-traumatic stress disorder (PTSD), depression, schizophrenia, and many others. Most importantly, CBD is incredibly safe, and not addictive. Even young children can tolerate daily doses of up to twenty milligrams (20 mg) per kilogram (1 kg) of body weight (for a 175 pound adult, that’s more than 1,500 mg). The most common side effect of high-dose CBD is sleepiness. 

The results of the three large European cohort studies have been confirmed in two smaller New Zealand birth cohorts. Arsenault and colleagues (2002) reported a prospective study of the relationship between adolescent cannabis use and psychosis in a New Zealand birth cohort (n = 759). They found a relationship between cannabis use by age 15 and an increased risk of psychotic symptoms by age 26. The relationship did not change when they controlled for other drug use, but it was no longer statistically significant after adjusting for psychotic symptoms at age 11. The latter probably reflected the small number of psychotic disorders observed in the sample. Fergusson et al. (2003) found a relationship between cannabis dependence at age 18 and later symptoms that included those in the psychotic spectrum reported at age 21 in the Christchurch birth cohort. Fergusson and colleagues adjusted for a large number of potential confounding variables, including self-reported psychotic symptoms at the previous assessment, other drug use and other psychiatric disorders, but whether the association represents a link between cannabis use and psychotic symptoms specifically, or more general psychiatric morbidity, remains unclear.
Prescription medicine (Schedule 4) for therapeutic use containing 2 per cent (2.0%) or less of other cannabinoids commonly found in cannabis (such as ∆9-THC). A schedule 4 drug under the SUSMP is Prescription Only Medicine, or Prescription Animal Remedy – Substances, the use or supply of which should be by or on the order of persons permitted by State or Territory legislation to prescribe and should be available from a pharmacist on prescription.[81]
The effects of marijuana on each person depend on the type of cannabis and how much THC it contains, the way the drug is taken (by smoking or eating), the experience and expectations of the user, the setting where the drug is used, and whether alcohol or other drugs are also being used. Some people feel nothing at all when they first try marijuana; others may feel high (intoxicated and/or euphoric).

If you haven’t been bombarded with CBD marketing or raves about it from friends, get ready. This extract—which comes from either marijuana or its industrial cousin, hemp—is popping up everywhere. There are CBD capsules, tinctures, and liquids for vaping plus CBD-infused lotions, beauty products, snacks, coffee, and even vaginal suppositories. Already some 1,000 brands of CBD products are available in stores—and online in states that don’t have lenient cannabis laws. This is a tiny fraction of what’s to come: The CBD market is poised to exceed $1 billion by 2020, per the Chicago-based research firm Brightfield Group.
