How long is CBD detectable? Many consumers ask themselves this question – whether for health reasons or with regard to a possible drug test. As a responsible Swiss CBD brand, Herba di Berna explains the most important facts about CBD detectability, how long it remains in the body, its half-life and all influencing factors such as form of consumption, frequency and metabolism.
What does CBD detectability mean?

CBD detectability refers to how long cannabidiol (CBD) can be measured in the body after consumption – for example in blood, urine or saliva. It plays a role here:
How fast your metabolism works
How often you consume CBD
In what form you take CBD (e.g. oil, capsule, vape)
How high the dose is
How does the body process CBD?
CBD enters the body differently depending on the form of consumption and is excreted again at different rates:
| Form of consumption | Onset of action | Retention time in the body | Special features |
|---|---|---|---|
| Oral (oil, capsules) | 30-90 minutes | 1-2 days (one-off), up to 2 weeks (regular) | Low bioavailability (liver metabolism) |
| Inhalative (vaporizer) | a few seconds | 1-3 days | Fast absorption, fast elimination |
| Sublingual (under the tongue) | 15-30 minutes | similar to inhalation | Bypasses liver metabolism |
| Topical (cream, gel) | locally limited | Not systemically measurable | Only has an external effect |
💡 Tip from Herba di Berna: CBD oil is better absorbed if it is taken with a little fat (e.g. coconut oil, nuts, avocado).
CBD detectability : How long does it take to degrade?
The body absorbs CBD in different ways:
The half-life of CBD describes how long it takes for 50% of the active ingredient to be broken down in the body. This period varies depending on the form of consumption:
- Oral intake (e.g. oil): 2-5 days
- Inhalation (e.g. vape): approx. 31 hours
- Single application: usually <1 week
- Long-term use: >1 week, possibly up to 2 weeks
CBD detectability: single vs. regular consumption
| Consumer behavior | CBD detectability |
|---|
| One-time consumption | 1-3 days |
| Regular consumption | up to 14 days |
| High doses (>10 mg/day) | Potentially longer dwell time |
| Fast metabolism | Faster elimination |
| Slow metabolism | Extended detectability |

CBD detectability – Is CBD detectable in a drug test?
Good news: CBD itself is usually not relevant in drug tests, as these are designed for THC. However:
- Look out for products with less than 1% THC (legally permitted in Switzerland)
- It is best to choose THC-free isolates or broad spectrum products
- Only use laboratory-tested CBD products
👉 Herba di Berna guarantees precise THC declaration and also offers THC-free CBD options.
CBD and medication: Watch out for interactions
CBD can influence enzymes such as CYP3A4, which are involved in the metabolism of many drugs. As a result, CBD can influence the effect of other drugs:
- Reinforce (e.g. with antidepressants)
- Weakening (e.g. with blood thinners)
📌 Important: Always seek medical advice when taking medication.
Our recommendation as Herba di Berna

As a reputable CBD brand, we value quality, safety and education. Therefore:
Talk to doctors if you are taking medication
Only use high-quality, tested CBD products
Consume consciously and in moderation
Take breaks when there is uncertainty
Conclusion: How long is CBD detectable?
The detectability of CBD in the body depends on several factors – in particular the form of consumption, frequency, dose and individual metabolism. In general:
- Single use: CBD usually excreted after 1-3 days
- Regular consumption: detectability up to 2 weeks possible
- CBD is not the same as THC – don’t worry with reputable products
- Best absorption when taken with a little fat
At Herba di Berna you will find CBD oil, CBD flowers & THC-free products that are tested for purity and transparency.
