"We still don't fully understand all of the mechanisms involved in CBD's actions," says Marcel Bonn-Miller, Ph.D, who studies CBD and its effects, primarily on PTSD. "We know some pieces but definitely not the whole story at this point. A lot of our understanding of the many potential benefits of CBD is rooted in work either on the cellular level or in preclinical models with rodents."
The manufacturer will probably give you a recommended dosage, but bear in mind that this isn’t set in stone. What you need to find is your own minimum effective dose. “Minimum effective dose” is a medical term which refers to the amount of a substance you need for the results you want, and above which, the substance doesn’t increase in effectiveness.
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.
To further ensure the reliability of our CBD isolate, we hold it to the same strict Triple Lab Tested™ standard that all HempMeds® products must go through. This lab testing process uses ISO/IEC 17025:2005 accredited testing labs to carefully examine our hemp oil. These labs test our hemp oil for an accurate concentration of cannabinoids and the presence of mold, mildew, fungus, toxins, heavy metals, and residual solvents to protect the end user from any contamination.
That's not to say CBD-infused creams definitely won't reduce your acute pain or muscle soreness. That's because pretty much all of these creams on the market right now have other scientifically-proven analgesic compounds, like menthol, camphor, and capsaicin which are also found in other, non-CBD topical pain relievers. "Any cream with a heating or cooling sensation desensitizes the nerves to pain by distracting them with stimuli on top," Dr. Colberg explains. Plus you're often massaging the area as you apply, which improves circulation and reduces muscle spasms, he adds.
Yes, CBD oils made from marijuana (sativa or indica) can have higher concentrations of both CBD–as well as CBN and THC (the latter is the “main attraction” because it’s psychoactive). But because not everyone can lawfully buy them (and those who can must purchase in person from a state-licensed dispensary) and they’re not available online except to customers living in certain recreational-weed-legal states, they aren’t being reviewed here. Also, MJ-derived CBD oils are not as widely produced and sold.
Quality is a particular concern, because cannabis plants easily soak up heavy metals from pesticides and other contaminants, Marcu says. If you are buying online, look for a company that documents how it tests its products. (If the website doesn’t indicate this, call and ask.) “Buying from a reputable manufacturer is crucial, because it matters how the plant is cultivated and processed,” Dr. Maroon says. One clue that a company is cutting corners: too low a cost. Good CBD is pricey—a bottle of high-quality capsules is sold in Cohen’s office for $140. But for many, it’s worth the money. Roth spent $60 on her tiny bottle. But when her energy returned the day she started taking CBD, she decided that was a small price to pay.
Inhibited liver function: The liver regulates the way different drugs are metabolized within the body; this process is known as hepatic drug metabolism. Higher-than-average doses of CBD oil can slow the hepatic drug metabolism process. As a result, users may not be able to process other drugs as quickly. This is particularly concerning for CBD oil users who also take prescription medications.
Up until recently, it was the psychoactive component of cannabis, tetrahydrocannabinol (THC), which received most of the attention for its medicinal benefits, as well as its ability to produce psycho- tropic effects. Now, with medical marijuana gaining ground across the country, researchers are discovering the amazing properties of additional cannabinoids. But what makes CBD so special?
If you don't live in a legalized state, you can typically still get CBD-infused creams. Since there's no regulation or standardized testing, your best bet is to find trustworthy brands who use creams free of toxins but with additional pain relievers like menthol, capsaicin, lemongrass, or camphor. Try Mary's Nutritionals Muscle Freeze ($70; marysnutritionals.com) or Elixinol's CBD Rescue Balm ($40; elixinol.com).
In addition to acting on the brain, CBD influences many body processes. That’s due to the endocannabinoid system (ECS), which was discovered in the 1990s, after scientists started investigating why pot produces a high. Although much less well-known than the cardiovascular, reproductive, and respiratory systems, the ECS is critical. “The ECS helps us eat, sleep, relax, forget what we don’t need to remember, and protect our bodies from harm,” Marcu says. There are more ECS receptors in the brain than there are for opioids or serotonin, plus others in the intestines, liver, pancreas, ovaries, bone cells, and elsewhere.
As a consumer, you can look at the manufacturer's website to see whether they batch-test their products, or ask them directly. You could also send a sample of your CBD oil to a testing facility yourself, something Bonn-Miller says he would do if he were trying to treat someone with a severe issue such as epilepsy. Testing can also determine whether the product contains pesticides, heavy metals, or other toxins.
Most CBD oils are available in round-number concentrations such as 250mg, 500mg, and 1,000mg. While these strengths accommodate many CBD users, they may not be sufficient for those with preferences that fall outside round numbers. NuLeaf Naturals offers a less conventional selection of concentrations: 240mg, 725mg, 1,450mg, 2,425mg, and 4,850mg. This range ensures that most users will find a strength that works for them.

If you live in a state where CBD is legal for your condition, it’s best to buy it from a state-regulated dispensary. But even there, oversight is uneven. “I feel safe being a cannabis consumer in Colorado, since the state tracks everything from seed to sale, but I didn’t the first few years after cannabis became legal,” when the rules were still taking shape, says Robyn Griggs Lawrence, the Boulder author of The Cannabis Kitchen Cookbook, which features recipes for cannabis edibles.
Sagely Naturals tests its products three times: the raw cannabidiol is evaluated by extractors, then by another third party lab. Finally, when the company receives the final product, Sagely randomly selects bottles to test for the third and final time. These tests ensure that the product is devoid of GMOs, solvents, chemicals, heavy metals, pesticides, herbicides, and THC.
Cost is another consideration. Most CBD oils are sold in concentrations of 300 to 750 mg, although this may range from less than 100 mg to more than 2,000. A good indicator of price-point is the cost per milligram. Low-cost CBD oils usually fall between five and 10 cents per mg; mid-range prices are 11 to 15 cents per mg; and higher-end oils cost 16 cents per mg or higher. Given these varying per-milligram costs, a bottle of CBD oil may be priced anywhere from $10 or less to $150 or more.
Preliminary research indicates that cannabidiol may reduce adverse effects of THC, particularly those causing intoxication and sedation, but only at high doses. Safety studies of cannabidiol showed it is well-tolerated, but may cause tiredness, diarrhea, or changes in appetite as common adverse effects. Epidiolex documentation lists sleepiness, insomnia and poor quality sleep, decreased appetite, diarrhea, and fatigue.
