Jan 5, Not that long ago, I would not have been able to tell you what the acronym “CBD” stood for, let alone what it was used for. CBD, or cannabidiol. Dec 26, Suddenly, CBD is everywhere. CBD, short for cannabidiol, a non-psychotropic component of cannabis and hemp, is being promoted as the. May 8, CBD (Cannabidiol) is extremely popular these days, being touted as the cure for nearly everything from anxiety to pain to inflammation. What is.
or cannabidiol, the CBD, Is real? about hype
Yes, in the laboratory CBD can be used to treat anxiety and even psychosis in humans. In mice, CBD has been used to decrease inflammation and by association, pain due to researcher cause broken legs.
All of these studies used very high doses of CBD. The equivalent of mg per day! Lower doses were shown to be useless. CBD has also been very successful in treating epileptic seizures — in children who have rare, genetic seizure disorders.
Did you notice how many adjectives I just used there? These studies are very interesting, but do not necessarily apply to otherwise healthy adult epileptics. So why are there so many powerful testimonials to the benefits of CBD? Why are so many companies out there selling CBD? Placebo is a wonderful thing. What is placebo actually? However, if the user believes that the substance is supposed to do something, then sometimes that thing does happen.
The Placebo Effect is real and powerful, and works because many symptoms like anxiety or pain are perceptions of our brains. If we can influence our beliefs with an inactive substance, sometimes we perceive a change in our symptoms. It could be any inactive substance that we believe in.
Specifically, we have an interest in developing new drugs for the treatment of pain that possess lessened drug abuse potential, and therapeutic interventions for drug abuse.
Although there is scientific interest in the use of CBD for both pain and drug addiction, as well as many other medical indications, there is a lot that we still do not know about CBD. Drugs affect the body by binding and acting at various protein molecules, usually on the surface of the cells in the body, called receptors. These receptors then send signals that can impact bodily functions. Only one of them, the cannabinoid type 1 receptor CB1R , is responsible for the high from marijuana.
These cannabinoid receptors are predominately found on nerve cells located throughout the body, including the brain. CBD also does not bind or act on the other cannabinoid receptor, the cannabinoid type 2 receptor CB2R , predominately found on immune cells.
In contrast, THC binds and activates both of these receptors. Studies indicate that CBD does, however, act on several other types of receptors. These include the serotonin 5-HT1A receptor, which can help regulate sleep , mood , anxiety and pain. However, scientists do not yet understand the exact manner in which CBD acts on the body. Likewise, many health-related anecdotal claims pertaining to CBD are not founded on solid scientific evidence, and may be due to well-documented placebo effects.
There is strong evidence, however, that CBD has enduring health benefits in the treatment of intractable epilepsy. This strain of marijuana was named after Charlotte Figi, who struggled with intractable pediatric epilepsy until she was given oil extracted from the strain, which contains a higher CBD-to-THC content.
Clinical trials with Epidiolex for the indications of Dravet syndrome and Lennox Gastaut syndrome, two forms of pediatric epilepsy, were resoundingly positive. In June , the Food and Drug Administration approved Epidiolex for treatment of these two forms of epilepsy in children that have not responded to other treatments.
These two syndromes are associated with genetic mutations in two genes that are important in the regulation of sodium ions. Nerve cells regulate the way they send signals by how ions, or molecules with either an overall positive or negative electric charge, flow in and out of their cells.
The most common ions that regulate nerve cell signaling are sodium, potassium, calcium and chloride. These ions move in and out of the cell via pores known as ion channels. In many forms of epilepsy, however, the movement of ions is not properly controlled. The study from Indiana University found that CBD can directly inhibit the aberrant flow of sodium ions in nerve cells that have sodium channelopathies.
Importantly, CBD does not seem to impact the flow of sodium in healthy nerve cells. Although CBD has marked effects on these sodium channelopathies, this does not mean that CBD will produce meaningful benefits to other forms of epilepsy. Other forms of epilepsy are linked to regulation problems related to the flow of potassium ions in cells. This type of pediatric epilepsy is resistant to all known therapeutics, including CBD.
There are also claims that CBD can be used to address pain. And indeed, mounting evidence in pre-clinical laboratory studies show that CBD may be of use for the treatment and prevention of neuropathic pain, or an amplified response that may be due to nerve cell damage.
In a mouse model of this type of pain, CBD injections prevented and reversed the development of one hallmark sign of neuropathic pain , called mechanical allodynia. This is the sensation of pain due to a non-noxious stimulus, such as the feeling of clothing on an area of skin that has a sunburn.
A new study from McGill University in Montreal, Canada, shows that oral administration of CBD produces these same effects in rats with a similar type of pain. In both of these studies, the scientists discovered that these effects are likely due to actions at serotonin receptors. A study from scientists at the University of Kentucky suggested that CBD applied to the skin, or transdermal CBD, may reduce inflammation in a rat model of arthritis.
However, additional studies from the laboratory at Temple University show that CBD does not work for all types of pain when tested in animals. An important caveat to these findings is that not all compounds that produce effects in rodent pain studies will work in humans. Further, most of these studies examined the effects of injected CBD. So far, there is little evidence showing therapeutic effects of either edible or transmucosal, the administration of a drug across a mucous membrane, CBD for pain.
