CBD may offer an option for treating different types of chronic pain. A study from the European Journal of Pain showed, using an animal model, CBD applied on the skin could help lower pain and inflammation due to arthritis. Another study demonstrated the mechanism by which CBD inhibits inflammatory and neuropathic pain, two of the most difficult types of chronic pain to treat. More study in humans is needed in this area to substantiate the claims of CBD proponents about pain control.
CBD stands for cannabidiol. It is the second most prevalent of the active ingredients of cannabis (marijuana). While CBD is an essential component of medical marijuana, it is derived directly from the hemp plant, which is a cousin of the marijuana plant. While CBD is a component of marijuana (one of hundreds), by itself it does not cause a "high." According to a report from the World Health Organization, "In humans, CBD exhibits no effects indicative of any abuse or dependence potential…. To date, there is no evidence of public health related problems associated with the use of pure CBD."
Some CBD manufacturers have come under government scrutiny for wild, indefensible claims, such that CBD is a cure-all for cancer, which it is not. We need more research but CBD may be prove to be an option for managing anxiety, insomnia, and chronic pain. Without sufficient high-quality evidence in human studies we can’t pinpoint effective doses, and because CBD is currently is mostly available as an unregulated supplement, it’s difficult to know exactly what you are getting. If you decide to try CBD, talk with your doctor — if for no other reason than to make sure it won’t affect other medications you are taking.
Is CBD safe?

CBD is commonly used to address anxiety, and for patients who suffer through the misery of insomnia, studies suggest that CBD may help with both falling asleep and staying asleep.
CBD has been touted for a wide variety of health issues, but the strongest scientific evidence is for its effectiveness in treating some of the cruelest childhood epilepsy syndromes, such as Dravet syndrome and Lennox-Gastaut syndrome (LGS), which typically don’t respond to antiseizure medications. In numerous studies, CBD was able to reduce the number of seizures, and, in some cases, it was able to stop them altogether. Videos of the effects of CBD on these children and their seizures are readily available on the Internet for viewing, and they are quite striking. Recently the FDA approved the first ever cannabis-derived medicine for these conditions, Epidiolex, which contains CBD.
Side effects of CBD include nausea, fatigue and irritability. CBD can increase the level in your blood of the blood thinner coumadin, and it can raise levels of certain other medications in your blood by the exact same mechanism that grapefruit juice does. A significant safety concern with CBD is that it is primarily marketed and sold as a supplement, not a medication. Currently, the FDA does not regulate the safety and purity of dietary supplements. So, you cannot know for sure that the product you buy has active ingredients at the dose listed on the label. In addition, the product may contain other (unknown) elements. We also don’t know the most effective therapeutic dose of CBD for any particular medical condition.
We’ve covered the factors that determine how long it takes for CBD to work, but what about how long it takes to get CBD out of your system? Again, it depends on many of the aforementioned factors that determine the effectiveness of the cannabinoid itself.
You can consume CBD oil sublingually by placing a few drops of CBD under your tongue and rubbing it into the tissue there with your tongue or finger for at least 30 seconds to a minute before swallowing. This will allow the mucous membranes in your mouth to absorb the CBD, partially bypassing the digestive system and liver, for much quicker entry into the bloodstream. Effects may be felt within seconds. Just like when you ingest THC edibles though, you’ll get a second onset of effects a couple of hours later when the CBD that wasn’t absorbed sublingually makes it through your digestive system.
When it comes to easy, effective CBD dosing, transdermal patches have a lot going for them. Based on the same principles as nicotine or birth control patches, CBD patches deliver a long-lasting dose very efficiently. The cannabinoid readily diffuses into our skin, through our skin cells, and into the bloodstream, especially when it’s helped along by permeation enhancers. Patches can help with localized skin and muscle issues but they are right up there with smoking when it comes to getting as much of the CBD you consume into your bloodstream as possible. It’s also a discreet option that delivers a steady dose over hours.
How CBD affects drug test results
When you apply topical CBD products directly to your skin, the CBD is absorbed and slowly interacts with localized cannabinoid receptors. In some cases, CBD-infused topicals should be applied liberally to overcome the low cannabinoid absorption rate of the skin. With topical application, any CBD effects you feel will peak after about 90 minutes. This method of administration is often used for chronic pain in specific areas.

The metabolic rate of the individual also has some sway over how long CBD stays in the system. The body’s metabolism determines the time needed to break down and synthesize compounds, which affects how long it takes the body to process and metabolize the cannabinoid.
It’s not just your body that influences how long it takes CBD to work, but also the quality of the CBD product and how often it’s used. Once you acquire CBD oil, the next step is to find the optimal dosing regimen, including frequency of use. The answers will depend largely on the type of product, amount of CBD inside it, and the specific ailment you are targeting. Most reputable manufacturers will provide instructions on how to properly use the product, but experimentation may be required to find the optimal dose for you and your specific needs.
