Given the many restrictions and conditions, it can be difficult to set up a fully legal and functional pipeline for the production and sale of CBD oil. Because different countries allow different activities with regards to cultivation, processing, extracting, etc., of hemp, entrepreneurs have often set up production pipelines that span multiple countries, where hemp is cultivated in one country, while extraction takes place in another, lab testing in a third, and sales take place in yet another country. This obviously makes it harder to determine exactly where a CBD product comes from, who is responsible for its final quality, and what standards were followed. For that reason, thorough analytical testing of final products by certified third-party labs is an essential tool to guarantee the safety and composition of CBD oils.
Hemp Oil contains naturally occurring phyto-cannabinoids, including CBD. It is widely consumed for its numerous wellness properties: as mild analgesic, antiinflamatory, antioxidant and antiemetic to name a few. Sträva uses the finest, full-spectrum hemp oil sourced from respected growers in Europe and Colorado. This oil is naturally rich in phyto-cannabinoids, including CBD, as well as constituents such as amino acids, vitamins B1, B2 and D, omega-3 and omega-6 fatty acids, minerals zinc, calcium and magnesium. Hemp Oil and CBD are non-psychoactive and do not produce a "high."

Research suggests that CBD may exert some of its pharmacological action through its inhibition of fatty acid amide hydrolase (FAAH), which may in turn increase the levels of endocannabinoids, such as anandamide, produced by the body.[8] It has also been speculated that some of the metabolites of CBD have pharmacological effects that contribute to the biological activity of CBD.[42]
You only have to read the reviews under a CBD product on the Holland & Barrett website to see the extent to which anecdotal reports cannot be trusted. More than 100 customers gave Jacob Hooy CBD+ Oil five stars, with a few saying they always noticed if they missed a dose (presumably this made them less relaxed, although they did not reveal what they were taking it for), while 93 people gave it one star, saying it did nothing, or was too weak. One couple even said it gave them palpitations and a sleepless night. All these people had different conditions, expectations and situations. “And,” says McGuire, “you have to remember that anything can have a placebo effect.” While it looks unlikely that the recommended doses of these products will do any harm, McGuire’s guess is that doses are so small “that it’s like homeopathy – it’s not going to do anything at all”.
The only study that has tested the bioavailability of inhaled CBD is from 2014; it found a bioavailability of about 25 percent for 100 mg and 200 mg doses of CBD using a Volcano vaporizer. (The topical lotions are even less studied; there have been no clinical trials on them at all.) This is more efficient than ingesting CBD, in the same way that vaporizing THC is more efficient than eating it. To get an effect, you should ingest a different amount of CBD than you’d inhale ... but how much is that? How much is too much?

Determining risks and benefits through proper clinical trials remains highly desired, but these will take considerable time and funds. As a result, clinical data will not appear any time soon, while patients will not simply stop using the many CBD products to which they have become accustomed. Taking back regulatory control over CBD could therefore start with a more short-term and achievable approach, i.e., demanding accurate and proper labeling, reflecting in detail what each product does and does not contain, and how it was manufactured. For a clearer judgment of the potential therapeutic effects, the risks, but also the legality of a cannabis extract, it is important to know its exact composition. After all, published data from around the world has taught us that misleading labels as well as harmful contaminants are real and actual problems for CBD products. The analytical methodology and the third-party labs needed for this approach largely already exist, and could easily be optimized to quickly get a better grip on the unrestrained cannabinoid market. This approach would hold each producer strictly accountable for the quality and safety of their own products, as long as there are real legal consequences for those businesses that break the rules. Add to this a system for regular professional audits and inspections, and a crackdown on unsubstantiated health claims, and we have a reasonable system to ensure that CBD can be used responsibly by those who need it, until much needed clinical data become available.
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.

So far, by far the best medicinal relief I have found for my symptoms is a particular strain of cannabis flower called Harlequin — it contains an almost 3:1 ratio of CBD:THC, which is extremely rare and unique in the cannabis world. There are multiple studies you can find online showing the SYNERGISTIC effects of CBD combined with THC. When they are used together, they are much more medicinally effective than either one is on their own. Most cannabis strains today have zero CBD because growers realized everyone just loves their THC, but the Harlequin strain is a god send.

CBD is a safe, long-term aid which is why it has gained such momentum and why our customers are turning to it for relief. CBD, scientifically known as cannabidiol, is a non-psychoactive, organic compound found in the hemp plant. When it interacts with the body’s endocannabinoid system, CBD provides powerful health benefits without the side effects of conventional drugs.
The few CBD studies out there give us limited information, and hardly any about recreational CBD use. One study gave people different amounts of ingested CBD (100, 300, and 900 mg), as well as, for comparison, a placebo and Klonopin; those people then had to give a public speech, an action associated with high levels of anxiety in the broad populace. Neither 100 mg nor 900 mg, nor the placebo, had any effect. The 300 mg dose, though, did have a measurable calming effect on heart rate, blood pressure, and anxiety. (The Klonopin also worked.)

Carson, too, speculates that CBD might be able to reduce some of the jitteriness associated with caffeine intake, thus complementing it rather than canceling it out. “I can’t say I’ve spent much time in New York, but when I was thinking about talking to you, I got this vision in my head of a stereotypical taxi driver drinking a huge cup of coffee and being really alert but irritable,” he says. “And now if you add in a little CBD, they’re really alert but maybe a little more calm, and not as apt to honk the horn. I think that’s a potential area where there could be something good that comes from adding CBD to the coffee.”
Scientists have made a lot of progress in understanding how CBD produces its calming, pain-reducing, anti-inflammatory effects in the body—and there’s still more to learn. We know that CBD interacts with many different receptors, proteins, and other chemicals in the brain. These interactions create changes in the activity of neurotransmitters, hormones, and other cells throughout the brain and body. Through these interactions, CBD appears to be able to affect many of the body’s functions, from sleep-wake cycles and emotional regulation to inflammation, pain perception, and seizures.
