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.
As the CBD Pure Hemp Oil label warns, you should not take the supplement if you are breastfeeding or pregnant, as there isn’t enough information on how it could affect the baby. Also, some studies suggest a long-term heavy use of cannabis can have negative neuropsychologic and behavioral effects, and even cause acute pancreatitis, although the exact mechanisms are still unknown.

Transparency: Receptra Naturals’ website has a database where you can look up lab reports for their products. The first time we checked, we got some 404 errors for a couple of the lab reports, but these glitches seem to have been fixed since then. We were able to see third-party lab reports for all their tinctures (though, apparently not for their topicals). 
In fact, not only will CBD not make you high, it has been proven to counteract the psychoactivity of THC. This property makes CBD highly useful as a medical treatment for a wide range of conditions. In terms of the CBD products you can buy, the amount of THC present varies from none at all in a pure CBD Isolate to a minimal amount (less than 0.3%) in a Full-Spectrum CBD product.
Most human studies of CBD have been done on people who have seizures, and the FDA recently approved the first CBD-based drug, Epidiolex, for rare forms of epilepsy. Clinical trials for other conditions are promising, but tiny. In one Brazilian study published in 2011 of people with generalized social anxiety disorder, for example, taking a 600-mg dose of CBD (higher than a typical dose from a tincture) lessened discomfort more than a placebo, but only a dozen people were given the pill.

CBD is well tolerated in humans with doses up to 600 mg not resulting in psychotic symptoms (15). In the few small placebo-controlled studies performed, no significant CNS effects were noted. Oral CBD undergoes extensive first-pass metabolism via CYP3A4, with a bioavailability of 6%. Following single doses in humans, the half-life of CBD when taken orally is about 1 to 2 days.1 In vitro studies have shown that CBD is a potent inhibitor of multiple CYP isozymes, including CYP 2C and CYP3A (16, 17). Whether these in vitro observations are relevant at plasma concentrations likely to be seen in patients is unclear. In addition, given its metabolism via CYP3A4, clinical trials of CBD in patients receiving enzyme-inducing AEDs, such as carbamazepine or phenytoin, will require detailed pharmacokinetic studies.
CBD is the major non-euphorigenic component of Cannabis sativa. Some research is beginning to show that CBD is different than other well-studied cannabinoids. All cannabinoids function as ligands, meaning they dock onto the binding site of a protein and have the ability to modulate a receptor’s behavior. CB1 receptors are widely distributed, but are particularly abundant in areas of the brain, including those concerned with movement, coordination, sensory perception, emotion, memory, cognition, autonomic and endocrine functions.
Hemp Bombs is based in Tampa, Florida, and in addition to focusing on the purity and therapeutic effectiveness of their products, are dedicated to establishing themselves as a top brand in the industry with a specific target audience. One of our personal favorite products of theirs is the flavored CBD vape liquids, which are some of the best-tasting CBD vape juices we’ve ever had.

Although it is great that you have compiled a long list of the best CBD oils, so that we get some choice also as consumers, however, I rely believe in your well researched information that you share always, and so I feel the number 1. you shared, Purekana is going to make the choice for me. Ordering it tonight, and let’s see how my CBD journey goes from here. A bit nervous though!
The important thing is that you have to be SUPER careful when selecting CBD oils. Since the cannabis industry is not FDA-regulated, there have been dozens and dozens of companies trying to get away with selling very low quality (and even potentially toxic), “snake oils” that have been extracted using harsh chemical solvents like butane and hexane. Make sure you stay away from cheap products like these, as they could damage your health.

CBD works by attaching itself to specific receptors of the body’s own endocannabinoid system. The human body is known to produce cannabinoids of its own, which affect the cannabinoid receptors CB1 and CB2. The CB1 receptors are generally found in the brain, and deal with pain, mood and emotions, movement, appetite, among others. THC acts upon the CB1 receptors. Meanwhile, CB2 receptors are more commonly found throughout the immune system, affecting inflammation and thus pain. CBD is thought to act upon these receptors, by influencing the body to produce its own cannabinoids in order to rebalance itself.
These reports suffered from a number of design flaws, including incomplete baseline quantification of baseline seizure frequency, indeterminate time periods for outcome determination and, in some cases, inadequate (or missing) statistical analysis—in general, a lack of sufficient detail to adequately evaluate and interpret the findings. Limitations aside, several studies did report that administration of adjunctive CBD did not result in meaningful changes in seizure frequency (11–13).
Over the past few years, increasing public and political pressure has supported legalization of medical marijuana. One of the main thrusts in this effort has related to the treatment of refractory epilepsy—especially in children with Dravet syndrome—using cannabidiol (CBD). Despite initiatives in numerous states to at least legalize possession of CBD oil for treating epilepsy, little published evidence is available to prove or disprove the efficacy and safety of CBD in patients with epilepsy. This review highlights some of the basic science theory behind the use of CBD, summarizes published data on clinical use of CBD for epilepsy, and highlights issues related to the use of currently available CBD products.
Having a medical condition is difficult enough, but if that condition doesn’t respond to medical treatment, life can become a constant battle. Refractory epilepsy is also known as uncontrolled or drug-resistant epilepsy. This means that a person who is suffering from refractory epilepsies is not responding to traditional medicine and thus is unable to effectively manage his or her neurological disorder.
Schizophrenia is a disorder that generally requires heavy antipsychotic drugs just to manage daily life. However, this systematic review notes that such drugs “provide limited cognitive benefits,” which is extremely rough given the side effects antipsychotic drugs can have. As discussed in the review, CBD may be a possible alternative to such heavy prescription drugs.
Generalized pain, for instance, has dozens upon dozens of high profile research and clinical studies that have been carried out in universities and laboratories around the globe. One of the most well-publicized of these studies took place back in 2008, in which results determined that “cannabinoid analgesics (pain relievers) have generally been well tolerated in clinical trials … with acceptable adverse event profiles (meaning acceptable effectiveness for practical use).
Ranging from irritating to debilitating, joint pain can be tricky to treat. If your pain is mild, ibuprofen or acetaminophen might be adequate. But the worse it gets, the more likely you are to be prescribed antidepressants, muscle relaxants, or even opioids. Because of the side effects associated with these prescription medications, there has been quite a bit of research on CBD and joint pain — with promising results. Here are a few studies that point to CBD’s potential:
I have read about studies from Europe (not very specific I know) that suggest CBD might work better for some people if combined with some level of THC. Also, the getting high part can be helpful, although not for everybody, of course. A second point – I don’t hear very much about CBD eliminating or almost eliminating pain for people with severe pain. Helpful, but, so far at least, it doesn’t seem that CBDs can replace opioids or substantially reduce pain for all chronic pain patients. Maybe someday.
We have receptors for cannabinoids in the whole body, but the first type (CB1) are very dense in the pain pathways of the brain, spine, and nerves. The second type (CB2) are more important for the immune system but is also involved in inflammation. By gently acting on both pathways, our internal cannabinoids and CBD can balance both pain and inflammation [64].
This is the second time Moon Mother Hemp Company has placed among the top five brands on our ranking. The Colorado-based company, which was founded about a year ago, sets the bar very high for quality (including USDA-certified organic hemp) without charging the moon for its products. Their tinctures taste so good, you may be sad you don’t need more.
