One of the most common questions about CBD oil is how long it will take to work. In truth, we just don’t have enough studies to answer this question definitely. Read on to understand what the early research shows.<\/p>\n
The most important thing to remember is that that the only approved use of CBD oil comes in the form of prescription anti-seizure medication and further research needs to be done to decipher its benefits in other conditions [R<\/a>]. But that has not stopped many people from using it for a myriad of conditions. So we just don’t have enough studies to definitely answer this question. That being said, we will give you the latest research findings on CBD oil and try to answer this question as best as we can.<\/p>\n If you are thinking about taking CBD oil, remember to speak with your physician about it!<\/p>\n Being a relatively new product, CBD oil users often struggle to figure out the best way to take it. Among many questions, people often want to know how long it will take for CBD oil to work. Will you feel the effects after a few minutes, days, or weeks?<\/p>\n If you don\u2019t notice the effects after taking it for some time, you might feel frustrated and conclude that CBD oil doesn\u2019t work.<\/p>\n First, you want to make sure that you\u2019re not missing out on any important factors that affect the onset of the effects – such as the delivery form, product composition, dosing regime, and your health status.<\/p>\n Below is a comprehensive list of the factors that will determine how long it will take until CBD oil starts working.<\/p>\n The delivery method is probably the factor that most strongly influences the time until the onset of the effects.<\/p>\n Some forms will allow CBD to quickly pass into your blood and reach its targets. In contrast, others will release CBD much slower, but their effects will last longer.<\/p>\n There are two main types of oral CBD oil:<\/p>\n Fast-release forms <\/b>are applied directly in the mouth. Although you will eventually swallow part of the liquid, you will absorb most of the CBD through the blood vessels under your tongue, along your gums, and on the inner lining of your mouth.<\/p>\n Thus, CBD will bypass your digestive system and be released directly into your bloodstream. As a result, the effects will start to kick in after only 15-30 minutes. They will be strongest when your blood CBD levels peak (~2-4 hours) and may last up to 6 hours [R<\/a>+, R<\/a>].<\/p>\n Conversely, you will need to digest slow-release forms<\/b> and should feel the effects 30-180 minutes after taking them. CBD has to pass from the gut into the liver before being released into your bloodstream. Liver enzymes break down part of CBD, so less will reach the blood (first-pass metabolism<\/i>) [R<\/a>+, R<\/a>, R<\/a>].<\/p>\n However, slow-release forms do have an advantage: their effects are sustained over a longer period of time. You can expect them to last up to 8 hours [R<\/a>+].<\/p>\n When and for how long you will feel the effects of topical forms depend on various ingredients that alter how well CBD penetrates the skin. According to users, you may start noticing the effects after 30-120 minutes [R<\/a>+].<\/p>\n Creams, lotions, and balms act locally, while transdermal patches also deliver CBD into the bloodstream. For example, CBD oil patches effectively reduced inflammation in animal studies [R<\/a>, R<\/a>].<\/p>\n Together with smoking medicinal cannabis<\/a>, vaping CBD oil is the fastest way to absorb CBD. Vaping is, however, preferable because it irritates the lungs less and produces fewer toxic byproducts such as carbon monoxide [R<\/a>, R<\/a>+].<\/p>\n Each inhalation will immediately release CBD into your lungs, which quickly passes into your bloodstream. You may notice the effects after only 5-15 minutes. However, blood CBD levels will start declining after 1 hour and the effects will only last 2-4 hours [R<\/a>+, R<\/a>].<\/p>\n CBD is also available in anal and vaginal suppositories<\/b>. Similar to topical forms, their effects may be strongest locally – in the mucosal tissue, nerves, and muscles of the anus and vagina. Because these areas are very rich in blood vessels, part of the CBD may pass into the blood and reach other areas [R<\/a>].<\/p>\n How fast you will feel the effects depends on the exact ingredients, e.g. oils and additives used. You will usually feel the local effects quickly, while it will take a couple of hours for CBD from anal suppositories to reach the bloodstream [R<\/a>].<\/p>\n It\u2019s important to choose high-quality CBD oil from reputable vendors. Low-quality products may have less CBD than stated on the label, meaning they will take longer to work – if at all [R<\/a>].<\/p>\n In addition, be sure to check the expiry date and keep the packaging in a cool and dry place protected from direct sunlight<\/a> to prevent degradation of the active compounds.<\/p>\n Plant-derived extracts (also called full-spectrum CBD oil) also contain other plant compounds that slow CBD absorption – a drawback if you need quick relief. However, these compounds act in synergy and enhance the effects of CBD at high doses, which may be preferable for chronic problems [R<\/a>].<\/p>\n Similarly, capsules and edibles release CBD slower if they contain ingredients such as fiber [R<\/a>].<\/p>\n In turn, CBD is a fat-soluble molecule and will be absorbed faster and better in combination with fats (e.g., CBD cakes with butter) [R<\/a>].<\/p>\n Whether your condition is acute or chronic may determine how long it will take CBD to work. Users with chronic conditions often overlook this one.<\/p>\n As a rule of thumb, single doses may relieve acute, episodic conditions (such as panic attacks), while chronic conditions (such as arthritis) may require sustained CBD therapy.<\/p>\n Below is an overview of how long it took CBD oil to work in clinical trials, by health condition.<\/p>\n People with acute anxiety<\/a> episodes responded quickly to oral CBD (capsules or liquid solution). It was effective after 90-160 minutes in those with anxiety caused by stress<\/a>, social phobia, and heroin craving [R<\/a>+, R<\/a>, R<\/a>+, R<\/a>, R<\/a>+].<\/p>\n In contrast, chronic anxiety needed longer-term therapies. CBD normally improved anxiety – and other symptoms – in 4-8 weeks in people with PTSD<\/a>, fragile X syndrome, and autism [R<\/a>, R<\/a>, R<\/a>, R<\/a>].<\/p>\n Only one clinical trial tested pure CBD for chronic pain<\/a>. In this study, CBD improved pain from kidney transplants after repeated use during 1-3 weeks [R<\/a>].<\/p>\n CBD-rich preparations reduced pain after 12 weeks in girls with adverse effects from the HPV vaccination, 1-7 months in children with complex movement disorders, and 1-3 months in people with migraines<\/a> and cluster headaches<\/a> [R<\/a>+, R<\/a>+, R<\/a>+].<\/p>\n A mouth spray with the same amount of CBD and THC<\/a> (nabiximols) was far more commonly used for chronic pain in clinical trials. It relieved rheumatoid arthritis pain after 5 weeks, multiple sclerosis<\/a> and nerve pain within 4-10 weeks, and cancer pain in 2-5 weeks [R<\/a>, R<\/a>+, R<\/a>, R<\/a>, R<\/a>+, R<\/a>+, R<\/a>+, R<\/a>+].<\/p>\n In people with insomnia, CBD improved sleep quality<\/a> after 1-2 months [R<\/a>+, R<\/a>].<\/p>\n Similarly, CBD oil improved sleep disturbances from Parkinson\u2019s disease, fragile X syndrome, and PTSD within 1-2 months [R<\/a>+, R<\/a>+, R<\/a>, R<\/a>, R<\/a>].<\/p>\n CBD reduced seizure frequency and severity in people with epilepsy who took it for 4-14 weeks [R<\/a>+, R<\/a>+, R<\/a>+, R<\/a>+].<\/p>\n In people with schizophrenia<\/b><\/a>, CBD started improving the symptoms after 2-6 weeks [R<\/a>, R<\/a>+, R<\/a>].<\/p>\n In regular cannabis smokers, a 10-week therapy with CBD improved adverse effects from THC use such as depression<\/a> and psychosis [R<\/a>].<\/p>\n After 13 weeks, CBD reduced the levels of a hormone that raises LDL cholesterol<\/a> (resistin) and increased gastric inhibitory polypeptide, which stimulates insulin<\/a> release in response to high blood sugar, in people with type 2 diabetes [R<\/a>].<\/p>\n According to a clinical trial on 56 people, taking CBD oil twice daily increases its blood levels better than taking it just once in the morning. Thus, it may help keep CBD levels steady [R<\/a>].<\/p>\n So if you use CBD more frequently, you may reach the required levels quicker [R<\/a>+].<\/p>\n This may be especially important for people with chronic health problems who need a stable supply of CBD oil to feel its effects. Consistency is crucial, and missing doses may prevent you from reaching high-enough CBD levels.<\/p>\n You will need less CBD oil if you are lighter and you are likely to feel the effects faster. But since CBD is stored in fat, heavier people – who tend to have more body fat – may feel the effects over a longer period of time. In line with this, exercising will quickly release CBD stored in fat [R<\/a>+, R<\/a>].<\/p>\n Being fat-soluble, CBD is absorbed through the small bowel. Your gut health – particularly, your microbiome composition<\/a> – will determine how quickly and efficiently you absorb it [R<\/a>].<\/p>\n Once in the bloodstream, CBD rapidly passes into deep tissues. However, health conditions can alter its distribution, e.g. a leaky blood-brain barrier<\/a> [R<\/a>+].<\/p>\n Genetics may also play a role. Genetic variants of CBD targets (such as FAAH<\/a>, TRPV1<\/a>, 5HT1A<\/a>, or GPR55) can make you prone to responding faster or slower [R<\/a>, R<\/a>, R<\/a>].<\/p>\n If you don\u2019t feel the effects of CBD oil, even after carefully considering all the above-described factors, it\u2019s possible that you are not taking the right dose or that CBD oil just does not work for you. Speak with your doctor about any issues you might be having.<\/p>\nSnapshot<\/b><\/span><\/h3>\n
