One of the most common questions about CBD oil is how long it will take to work. In truth, there is no simple answer that applies to everyone. Read on to understand when you will feel the effects and why it might not happen overnight.
When Will You Feel the Effects of CBD Oil?
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?
If you don’t notice the effects after taking it for some time, you might feel frustrated and conclude that CBD oil doesn’t work.
First, you want to make sure that you’re not missing out on any important factors that affect the effects onset – such as the delivery form, product composition, dosing regime, and your health status.
Below is a comprehensive list of the factors that will determine how long it will take until CBD oil starts working.
- CBD oil can relieve acute conditions, such as panic attacks, in a couple of hours
- Vapes and mouth sprays are better for acute conditions
- People with chronic problems may need to wait a couple of months
- Capsules release a steady supply of CBD and are better for chronic conditions, taken twice daily
- Your microbiome and genes can affect how quickly you will respond
- If you’ve been taking CBD oil for 4-5 months and still don’t feel anything, you’re probably not dosing it right
How Long It Takes for CBD Oil to Work by Product Type & Composition
The delivery method is probably the factor that most strongly influences the time until the onset of the effects.
Some forms will allow CBD to quickly pass into your blood and reach its targets. In turn, others will release CBD much slower, but their effects will last longer.
There are two main types of oral CBD oil:
- Fast-release forms: tinctures and mouth sprays.
- Slow-release forms: capsules, tablets, edibles (such as gummies, lollipops, and cakes), and teas.
Fast-release forms 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.
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 [1+, 2].
Conversely, you will need to digest slow-release forms 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) [1+, 2, 3].
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 [1+].
When and for how long you will feel the effects of topical forms depends on various ingredients that alter how well CBD penetrates the skin. According to users, you may start noticing the effects after 30-120 minutes [1+].
Together with smoking medicinal cannabis, 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 [6, 1+].
Each inhalation will immediately release CBD into your lungs, which quickly passes into your bloodstream. You’ll 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 [1+, 2].
CBD is also available in anal and vaginal suppositories. Similar to topical forms, their effects are 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 .
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 .
Another possibility is to use injectable CBD. This form allows immediate delivery into the bloodstream, meaning its effects can be even faster than with vaping. However, this method would require medical supervision. A further disadvantage is that the effects will last shorter than with any other form .
Product Quality & Composition
It’s 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 .
In addition, be sure to check the expiry date and keep the packaging in a cool and dry place protected from direct sunlight to prevent degradation of the active compounds.
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 is great for chronic problems .
Similarly, capsules and edibles release CBD slower if they contain ingredients such as fiber .
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) .
How Long it Takes for CBD Oil to Work by Health Condition
Whether your condition is acute or chronic will determine how long it will take CBD to work. Users with chronic conditions often overlook this one.
As a rule of thumb, single doses can relieve acute, episodic conditions (such as panic attacks), while chronic conditions (such as arthritis) may require a sustained CBD therapy.
Below is an overview of how long it took CBD oil to work in clinical trials, by health condition.
1) Anxiety (Acute & Chronic)
People with acute anxiety episodes responded quickly to oral CBD (capsules or liquid solution). It was effective after 90-160 minutes in those with anxiety caused by stress, social phobia, and heroin craving [14+, 15, 16+, 17, 18+].
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 and cluster headaches [24+, 25+, 26+].
A mouth spray with the same amount of CBD and THC (nabiximols) was far more commonly used for chronic pain in clinical trials. It relieves rheumatoid arthritis pain after 5 weeks, multiple sclerosis and nerve pain within 4-10 weeks, and cancer pain in 2-5 weeks [27, 28+, 29, 30, 31+, 32+, 33+, 34+].
3) Sleep Disorders
6) THC Side Effects
After 13 weeks, CBD reduced the levels of a hormone that raises LDL cholesterol (resistin) and increased gastric inhibitory polypeptide, which stimulates insulin release in response to high blood sugar in people with type 2 diabetes .
Dosing & Other Factors that Impact When You’ll Feel CBD Oil’s Effects
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 .
So if you use CBD more frequently, you may reach the required levels quicker [6+].
This is 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.
Factors Unique to You
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 – will feel the effects over a longer period of time. In line with this, exercising will quickly release CBD stored in fat [49+, 50].
What if I Still Don’t Feel Anything After Taking CBD oil?
If you don’t feel the effects of CBD oil, even after carefully considering all the above-described factors, you are probably not taking the right dose.

Vendors sell CBD oil on Amazon, but many of them do not fulfill quality standards. Some don’t even specify the CBD content in their products, while others sell hemp oil with little or no CBD. Most of these vendors are not to be trusted.
We recommend the following brand, which specifies quality procedures and CBD content in their products:

When you will feel the effects of CBD oil mainly depends on how and why you are taking it. The quality and additional ingredients in the product you’re using also weigh in.
CBD oil can relieve acute conditions, such as panic attacks, in a couple of hours. Vapes and mouth sprays are the best choice if you need quick relief.
People with chronic problems may need to wait a couple of months. For example, CBD oil improves sleep in 1-2 months, seizures in 4-14 weeks, and type 2 diabetes in up to 13 weeks.
Capsules are the best choice for chronic conditions. They release a steady supply of CBD, which starts to act in 1-3 hours. Capsules should be taken twice daily with dietary fats for optimal results.
Additionally, your microbiome, body fat, and genes can affect how quickly you will respond to CBD oil.
If you’ve been taking CBD oil for 4-5 months and still don’t feel anything, you’re probably not taking the right formulation or dosage. Readjust and track your response.
