I tried the CBD oil that comes from hemp cause that’s all that’s legal where I live and was really hoping it would help with my back pain but it does absolutely nothing. Might as well have bought a bottle of vegetable oil & saved $150. I think it’s the THC that’s in medical marijuana that offers true pain relief, looking forward to it being legal across the country not just in 30 states.
Some manufacturers ship CBD products nationally, an illegal action which the FDA has not enforced in 2018, with CBD remaining as the subject of an FDA investigational new drug evaluation and is not considered legal as a dietary supplement or food ingredient as of November 2018. CBD is openly sold in head shops and health food stores in some states where such sales have not been explicitly legalized.
Naturally, the testimonies of these experts were based on a comprehensive literature review, an endeavor which we have also undertaken, albeit in a less official capacity. While many new products have been hailed as a panacea in their times, and many web sources certainly allude to this status for CBD, our objective was more modest – presenting ten possible benefits of cannabidiol where sufficient evidence exists to back up the claims.

Cannabinoids affect the transmission of pain signals from the affected region to the brain (ascending) and from the brain to the affected region (descending). A 2011 study showed that CBD and CBC stimulated descending pain-blocking pathways in the nervous system and caused analgesia by interacting with several target proteins involved in nociceptive control. Authors concluded that the cannabinoids “might represent useful therapeutic agents with multiple mechanisms of action.”  The following year, researchers reported that CBD significantly suppressed chronic inflammatory and neuropathic pain without causing apparent analgesic tolerance in animals.  And then in 2013, researchers concluded that chronic pain patients prescribed hydrocodone were less likely to take the painkiller if they used cannabis. 
Studies in humans, including many of those cited below, have demonstrated that CBD dosage reduces anxiety (once again, compared to the increased levels of anxiety that THC produces), and that when you combine CBD with THC, it takes the anxiety edge off THC. This is due to the action of CBD on 5HT1A and TRPV1 receptors, both of which are involved in mitigating the anxiolytic, panic and fear responses to stress.
I started using marijuana as a teen. The main reason that kept me using it was the fact that it made my stomach stop hurting. I thought I just had anxiety problems or an ulcer. I have no Idea It’s one of the reason that supress the pain I feel after I read this article from http://www.ilovegrowingmarijuana.com/cbd-in-medic…. Since reading is not my thing back then.
The hemp used to make this CBD oil is extracted from a special variety of sustainably raised, organic hemp that is specifically bred to contain naturally high concentrations of CBD, while still containing all of the natural cannabinoids, terpenoids, and other compounds of the original plant. The resulting oil then is strictly tested for purity and is free from pesticides and heavy metals.
After many conversations with my husband we decided to contact Dr. Christopher and we order 90-day cannabis treatment and the card was for cancer treatment amazingly, the cannabis oil has helped me with my fibromyalgia pain, joint pain, and chronic headaches. I had this pain for many years and it was getting worse. I literally have no pain now. My blood pressure had been creeping up over the years and was consistently pre-hypertensive, now it’s consistently on the low side of normal. I have not taken any other medication except the cannabis oil, supplements, and good clean healthy food over the years.
Manufacturers have different extraction and plant source methods which cause the CBD oil to have different levels of THC. It’s always advisable to check on the labels to check whether THC levels is less than 0.3 percent. It’s important to note that chances on intoxication are highly unlikely, but some THC found in CBD oils can show up in a drug test.
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.
So am I to assume, due to no response/deleted comment that my simple question was too difficult to answer? With all the technical & correct information you have on you GREAT website, can someone (?) not simply correct or acknowledge the FACT the your NOT using nano-particle size product? I am truly interesting (for my wife) in CBD, have done my research, and I love working with numbers which is why if found this discrepancy. Comments welcome, but avoidance is disturbing.
