Generally, CBD oil is made by combining an extract with a carrier fluid or oil. This question is best answered by looking at how the CBD oil was extracted. CBD oil can be extracted using CO2 systems or by using chemical solvents. Both methods produce a CBD oil byproduct that is then combined with a fluid like MCT oil, coconut oil, or olive oil so that it can be delivered to the body. Always check to make sure you know the CBD content of the products you purchase.

With an increasing number of options out there, choosing the right CBD oil brand may be confusing. Unfortunately, CBD oil is currently not regulated by the FDA, hence not all brands are organic, and not all include the same amount of or full-spectrum benefits. When choosing a CBD oil brand, look for organic, non-GMO, independently tested, full-spectrum hemp products.
For some people, however, regular strength CBD just doesn’t cut it. If you’re one of those people, you may require something a lot stronger. If you think that CBD “doesn’t work”, then it’s possible that you might need to step it up to something stronger. Whether you’ll be good with a 1000mg high-strength CBD oil or if you need to step up to the big leagues with the Hemp Bombs 4000mg vape juice is a matter of personal preference. Everyone’s body is different. What works for someone else may not work for you. Experiment and find the perfect dosage that works best for your unique needs.

Gloss and Vickrey conducted a Cochrane systematic review of the use of CBD in the treatment of epilepsy (11). Their methodology included only those trials that were randomized and controlled and excluded case series, case reports, and expert opinion. They were able to identify only 4 randomized controlled studies reported in the literature, and they included a letter to the editor and an abstract. The total number of subjects enrolled in these studies was 48 (11–14). While only four studies and a letter to the editor were in the actual analysis, the authors included a complete reference listing of all articles reviewed for inclusion.


To my understanding, neither CBD nor THC are effective for “severe” pain; rather, they work better for mild to moderate chronic pain. Often, with severe pain, the dosage of opiates can be decreased with concomitant use of medical cannabis or CBD and that decrease in dose makes their use safer. Concurrent use of THC does increase the analgesic effect of CBD, but it also adds the “high” which some people do not want as a side effect.
More recent experiments, involving the administration of a part CBD part THC solution, have yielded results that contradict the first supposition. At present, on the evidence that cannabidiol reduces some of the psychoactive effects of tetrahydrocannabinol (acting as a de facto antidepressant), scientists argue that cannabidiol has a holistic but indirect influence on all cannabinoid receptors in the endocannabinoid system. The main consequence of this impact seems to be an increase in the production of endocannabinoids. This is now the prevailing idea that accounts for the mountains of empirical evidence of how the benefits of cannabidiol are expressed at the cellular level.

Realistically, you’re going to be looking at a minimum dose of about 40mg CBD if you want to feel effects, at least that’s in my experience. That said, I’ve noticed that dosing can be kind of sensitive – if I take over about 80mg, it seems to start effecting me negatively while a 40-50 mg dose works wonders for me joint pain and sleep. Just my two cents. Best of luck
Customer Service: It’s difficult to find contact information on Calm by Wellness’s website, and their email address is listed incorrectly in two places (we tried sending them an email but it was not delivered). We were, however, able to get a response through Facebook, and the company does offer free shipping and a generous 30-day return policy on all orders.
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.
“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.
