Results of a Phase III study (N = 177) comparing Sativex, THC-predominant extract and placebo in intractable pain due to cancer unresponsive to opiates (Johnson and Potts 2005) demonstrated that Sativex produced highly statistically significant improvements in analgesia (Table 1), while the THC-predominant extract failed to produce statistical demarcation from placebo, suggesting the presence of CBD in the Sativex preparation was crucial to attain significant pain relief.
Using CBD for pain is personal and requires patience as you determine the best form of consumption for you. If you’re new to the world of CBD, talking with other patients is a great way to get information about products and to connect with a community of like-minded individuals. Some companies offer money-back guarantees if you’re not satisfied with the product. This may be a great way to comfortably try products. We believe that one critically important criteria when shopping for CBD products are considering the quality of the hemp or cannabis used and whether or not the product has been lab tested.

While research into the effects of CBD on specific conditions is important, a broader perspective on the relationship between CBD and the human body is necessary to understand how this unique compound works. Interestingly, many of the conditions that are supposedly helped by CBD have no well-understood cause, from acne to Alzheimer’s disease. However, one of the few common denominators between these conditions is the involvement of the endocannabinoid system (ECS) in their causes.
A study by Henquet and colleagues (2004) substantially replicated both the Swedish and Dutch studies in a 4-year follow-up of a cohort of 2437 adolescents and young adults between 1995 and 1999 in Munich. They found a dose–response relationship between self-reported cannabis use at baseline and the likelihood of reporting psychotic symptoms. As in the Dutch cohort, young people who reported psychotic symptoms at baseline were much more likely to experience psychotic symptoms at follow-up if they used cannabis than were cannabis-using peers without such a history.
It's important to know that although THC and CBD are the most studied components of cannabis, there are many more chemical compounds found within the plant, such as cannabigerol (CBG), cannabichromene (CBC), cannabidivarin (CBDV), tetrahydrocannabivarin (THCV), terpenes, and flavonoids. While there is still much to learn about these other chemicals, researchers in Israel have discovered that whole-plant cannabis extracts that contain these other chemicals are more beneficial than isolated extracts that contain just CBD or THC.
There are approximately 60 unique cannabinoids in cannabis plants, which can be classified as hemp plants or marijuana plants (there’s a difference!). CBD is one of them and is the second-most prevalent cannabinoid found in the plant; THC is another. This distinction is absolutely critical to understand because THC is the cannabinoid responsible for the “high” produced by traditional marijuana; it’s where the negative connotations and associations generally begin.
In this edition of Cannabis Conversations, Project CBD Director, Martin A. Lee, discusses the benefits of CBD, the "entourage effect" and the microbiome with Dr. Ethan Russo. A neurologist, scientist, and widely published author, Dr. Russo is currently the director of research and development at the International Cannabis and Cannabinoids Institute in Prague (www.icci.science).

NIDA provides research-grade marijuana for scientific study. The agency is responsible for overseeing the cultivation of marijuana for medical research and has contracted with the University of Mississippi to grow marijuana for research at a secure facility. Marijuana of varying potencies and compositions is available. DEA also may allow additional growers to register with the DEA to produce and distribute marijuana for research purposes.
Tried CBD at what the seller told me was the highest level sold by the company. It was a local company as I live in a state where Marijuana is legal. I have never used marijuana & can’t afford it, also I am still prescribed a limited amount of prescription pain medication. Have recently been reduced to half of what I’ve taken for 15 years. The CBD oil was $230.00 for an ounce & I live on a very limited income. It’s not a realistic expense for me. I also couldn’t tell that it helped with my pain or anxiety levels. It was worth trying though. Had been curious for some time.

In one study, researchers found that out of 150 reckless drivers who were tested for drugs at an arrest scene, 33 percent tested positive for marijuana and 12 percent tested positive for both marijuana and cocaine. Data also show that after smoking marijuana, people demonstrate the same lack of coordination on standard drunken-driving tests as do those who have had too much to drink.

CBD oil is also used by some people who have cancer. A few studies in mice have shown a reduction of cancerous tumors. But most human studies have involved research into the role of CBD oil in managing pain related to cancer and cancer treatment. The National Cancer Institute (NCI) has pointed to CBD as a possible option for relieving symptoms caused by chemotherapy.
