How Long Does CBD Last? Duration and Onset of Effects at a Glance

In brief: how long CBD works depends mainly on the form of intake. With oil under the tongue, the onset is usually described after about 15–45 minutes, with capsules or edibles later (approx. 30–90 minutes), and fastest when vaporised. The perceived effect can last several hours and is experienced differently by each individual.

One of the most common questions about cannabidiol is: how long does CBD actually last? There is no one-size-fits-all answer, because the duration of effect depends on several factors – above all on the chosen form of intake, the dosage and individual physical conditions. On this page, we summarise clearly what is described about the onset and duration of CBD's effects, without making sweeping promises.

As a general rule: if CBD is absorbed through the mucous membranes, for example as oil under the tongue, the effect can set in comparatively quickly. If, on the other hand, it is swallowed, it first passes through the digestive tract, which is why the onset is often described as later – but according to user reports, the effect can last longer.

What does “duration of effect” mean for CBD?

With CBD, a distinction is made between two things: the onset of effect (when something becomes noticeable) and the duration of effect (how long this impression lasts). Neither value is a fixed figure; they are empirical values that vary depending on the person and product. CBD is not intoxicating, and the time windows mentioned here are guideline values based on user experience, not guaranteed figures.

When do the effects of CBD start?

The onset depends on how quickly the cannabidiol is absorbed into the body. This is usually faster via the oral mucosa than via the digestive tract. The fastest onset is reported with vaporising.

How long do the effects last? (by form of intake)

CBD oil & drops

When used sublingually, the onset is often described as about 15–45 minutes and the duration as around 4–6 hours. More on this in our CBD oil section and on CBD drops.

CBD vapes & liquid

When vaporised, CBD enters the circulation quickly via the lungs – the onset is often reported after just a few minutes, but the duration tends to be shorter (about 2–4 hours).

See also CBD liquid.

CBD capsules & edibles

Swallowed products are absorbed via the digestive tract. The onset is therefore described as later (approx. 30–90 minutes), but according to user reports the effect can last longer (up to 6–8 hours).

Which factors influence the duration of effect?

In addition to the form of intake, dosage, body weight, metabolism and regularity of use play a role. The interplay of different cannabinoids can also influence perception. You can find guidance on the right amount in the CBD dosage section and on

CBD intake. Initial studies suggest that individual reactions can vary greatly.

Frequently asked questions about the duration of CBD effects (FAQ)

How long does it take for CBD to work?

That depends on the form of intake: after a few minutes when vaporised, after about 15–45 minutes with oil under the tongue, after around 30–90 minutes with capsules or edibles.

How long do the effects of CBD last?

Based on experience, between about 2 and 8 hours, depending on the form of intake, dosage and individual factors. There is no guaranteed duration.

Does CBD oil work faster than capsules?

Generally yes, as oil is absorbed sublingually via the oral mucosa, while capsules first pass through the digestive tract.

Why does CBD affect me differently than other people?

Metabolism, body weight, habituation and product quality can influence perception. Individual differences are normal.

Does the dosage influence the duration of effect?

It can influence the perceived intensity and duration. However, a higher dose does not automatically mean a longer or stronger effect.
