What is CBD?
Cannabidiol – the non-psychoactive cannabinoid
CBD, short for cannabidiol, is one of over 100 cannabinoids naturally present in the cannabis plant (Cannabis sativa L.). It was first isolated in 1940 by American chemist Roger Adams, and its chemical structure was fully elucidated in 1963 by Raphael Mechoulam and Yechiel Shvo at the Hebrew University of Jerusalem.
Unlike its more well-known cousin, THC (tetrahydrocannabinol), CBD is not psychoactive. This means that CBD does not cause intoxication, a "high", or alteration of consciousness. This property makes CBD particularly interesting for people who want to benefit from the properties of cannabinoids without experiencing the intoxicating effect of THC.
CBD is found in particularly high concentrations in specially selected cultivated hemp varieties, whose THC content is less than 0.3%. It is from these plants that most commercially available CBD products are made – including CBD oils, CBD flowers, capsules, edibles, and topical products.
Cannabinoids at a glance
The cannabis plant produces many chemical compounds called phytocannabinoids. In addition to CBD and THC, it includes CBG (cannabigerol), CBN (cannabinol), CBC (cannabichromene), and THCV (tetrahydrocannabivarin). Each of these cannabinoids has a unique action profile and interacts differently with the endocannabinoid system of the human body.
The entourage effect is particularly noteworthy: the combination of cannabinoids, terpenes, and flavonoids in the plant can produce a more pronounced effect than each substance taken individually. This is why many users prefer full-spectrum CBD products, which preserve the plant's natural cannabinoid profile, over pure CBD isolates.
How does CBD work in the body?
The effects of CBD are based on a complex interaction with the body's own endocannabinoid system (ECS) – one of the main regulatory systems of the human body.
The Endocannabinoid System (ECS)
The endocannabinoid system was only discovered in 1992 – ironically during research on cannabis. It is a complex cell-signaling system present in all mammals and plays a central role in maintaining homeostasis (internal balance). The ECS regulates many bodily functions, including sleep, mood, appetite, pain perception, immune response, memory, and reproduction.
The ECS consists of three main components: endocannabinoids (cannabinoids produced by the body, such as anandamide and 2-AG), cannabinoid receptors (CB1 and CB2), and enzymes responsible for the synthesis and breakdown of endocannabinoids (FAAH and MAGL).
Interestingly, CBD does not bind directly to CB1 or CB2 receptors like THC does. Instead, CBD acts as an allosteric modulator and influences the receptors indirectly. For example, it inhibits the FAAH enzyme, responsible for breaking down the endocannabinoid produced by the body, anandamide. Anandamide levels then increase in the body, which may contribute to the positive effects of CBD. Anandamide is also nicknamed the "bliss molecule" and plays an important role in regulating mood and pain perception.
CB1 Receptors
Central Nervous SystemCB1 receptors are primarily found in the brain and central nervous system – notably in the hippocampus, amygdala, basal ganglia, and cerebellum. They are involved in regulating pain perception, mood, memory, appetite, and motor control.
THC binds directly to CB1 receptors and thus causes the state of intoxication. CBD, on the other hand, acts as a negative allosteric modulator on CB1 – it slightly alters the shape of the receptor, so THC binds less strongly. This is why CBD can mitigate the psychoactive effect of THC. At the same time, CBD indirectly influences, via CB1, pain perception, anxiety, and mood.
CB2 Receptors
Immune System & PeripheryCB2 receptors are primarily found in immune cells, the spleen, tonsils, and gastrointestinal tract. They play a crucial role in regulating inflammatory processes and the body's immune response.
CBD has a higher affinity for CB2 receptors than for CB1 and acts as an inverse agonist. This means that CBD can modulate the activity of CB2 receptors, resulting in an anti-inflammatory effect. This property makes CBD particularly interesting for research on autoimmune diseases, chronic inflammation, and neurodegenerative diseases.
CBD effects beyond the ECS
The effects of CBD are not limited to the endocannabinoid system. CBD interacts with more than 65 different molecular targets in the body. Among the most important are:
Serotonin receptors (5-HT1A)
CBD activates the 5-HT1A serotonin receptor, which plays an important role in anxiety, depression, and nausea. This interaction explains CBD's anxiolytic and mood-regulating properties.
Vanilloid receptors (TRPV1)
CBD binds to TRPV1 receptors, involved in pain perception, inflammation, and body temperature. This activation may contribute to CBD's analgesic effect.
GPR55 receptors
CBD acts as an antagonist of the GPR55 receptor, sometimes called the 'third cannabinoid receptor'. Blocking this receptor could have anti-proliferative effects and is being researched in oncology.
PPAR-gamma receptors
CBD activates PPAR-gamma receptors, involved in regulating metabolism, inflammation, and cell proliferation. This activation presents neuroprotective and anti-inflammatory properties.

CBD effects on different areas
The effects of CBD in the body extend to many physiological and psychological areas. Here is an overview of the most studied fields of action of cannabidiol.
Sleep & recovery
CBD can improve sleep quality by reducing anxiety and restlessness – two of the most common causes of sleep disorders. A study published in The Permanente Journal (2019) showed that 66.7% of participants reported better sleep after taking CBD. CBD influences the sleep-wake cycle via the ECS and can particularly help with REM sleep behavior disorders and excessive daytime sleepiness. Unlike traditional sleeping pills, CBD does not disrupt the natural sleep architecture and does not cause dependence.
CBD oils for better sleepStress & anxiety
The anxiolytic effect of CBD is one of the best-documented effects. CBD activates the 5-HT1A serotonin receptor and reduces the activity of the amygdala – the brain's fear center. A Brazilian study (2019) showed that a single dose of 300 mg of CBD significantly reduced anxiety during a simulated public speaking test. CBD is also being researched for generalized anxiety disorder, social phobia, and post-traumatic stress disorder (PTSD).
Relaxing CBD flowersPain
CBD interacts with TRPV1 receptors and the ECS to modulate pain signals. Studies show promising results for neuropathic pain, arthritis, and chronic pain conditions. A review published in the European Journal of Pain (2020) confirmed that topically applied CBD significantly reduced pain and inflammation associated with arthritis in an animal model. CBD is being studied as a complementary option, especially for chronic pain where traditional analgesics cause adverse effects.
CBD oils for painInflammation
The anti-inflammatory effect of CBD is one of the most promising research areas. CBD inhibits the production of pro-inflammatory cytokines (TNF-alpha, IL-6, IL-1beta) and promotes the activity of anti-inflammatory pathways. Via CB2 receptors, CBD modulates the immune response and can thus reduce chronic inflammation. This property makes CBD interesting for diseases like Crohn's disease, rheumatoid arthritis, and multiple sclerosis.
CBD toleranceMood & well-being
CBD influences the serotonergic and dopaminergic systems and can thus improve mood. By inhibiting the FAAH enzyme, CBD increases the level of anandamide – an endocannabinoid known as the 'bliss molecule'. Preclinical studies suggest that CBD has properties that act quickly and are mediated by the 5-HT1A receptor. CBD can also improve emotional resilience and promote overall mental well-being.
Strains for well-beingNeuroprotective effect
CBD shows, in research, neuroprotective properties that could be relevant for neurodegenerative diseases. It acts as an antioxidant and reduces oxidative stress in the brain. Studies are examining CBD for Alzheimer's disease, Parkinson's disease, and multiple sclerosis. In the EU, a CBD-based medication (Epidiolex/Epidyolex) is already approved for the treatment of severe forms of epilepsy (Dravet syndrome, Lennox-Gastaut syndrome) – a key step for the recognition of CBD in conventional medicine.

Research on the effects of CBD has intensified exponentially in recent years. Here is an overview of the main findings and major clinical studies.
WHO Expert Committee on Drug Dependence
World Health Organization (WHO)
WHO published an in-depth critical review on CBD and concluded that CBD has a good safety profile, does not have abuse potential, and does not lead to dependence. The report confirmed that pure CBD has no psychoactive effects and recommended not classifying CBD as a controlled substance. This was a turning point for the international acceptance of CBD as a substance of interest.
CBD, Sleep, and Anxiety – The Permanente Journal
Shannon et al., The Permanente Journal, 23:18-041
In this large-scale case series involving 72 adults, CBD improved anxiety scores in 79.2% of patients and sleep quality in 66.7% from the first month. Anxiety scores remained low throughout the study, which lasted three months. Researchers concluded that CBD may be a useful supplement for anxiety disorders and sleep problems.
Epidiolex Approval – FDA & EMA
U.S. Food and Drug Administration / European Medicines Agency
The FDA approved Epidiolex (pure CBD) as the first cannabis-based medication for the treatment of Dravet syndrome and Lennox-Gastaut syndrome – two severe forms of childhood epilepsy. In phase III clinical trials, CBD reduced seizure frequency by up to 42% compared to placebo. The EMA granted approval for Europe in 2019 under the name Epidyolex.
CBD and Social Anxiety Disorder
Masataka, N. (2019). Frontiers in Psychology, 10:2466
A double-blind, placebo-controlled study showed that 300 mg of CBD significantly reduced anxiety symptoms in adolescents with social anxiety disorder. Participants had lower scores on the visual analog scale of anxiety and the Liebowitz Social Anxiety Scale compared to the placebo group.
CBD and Chronic Pain – Systematic Review
Argueta et al., Journal of Alternative and Complementary Medicine
This systematic review analyzed all available studies on CBD in pain management and found significant improvements in chronic pain, arthritis, and neuropathic pain conditions. The authors emphasized that CBD is particularly promising as a complement to existing pain therapies and has a favorable side effect profile.

Onset & duration of action
The speed and duration of CBD's action largely depend on the method of consumption. Each method has advantages and disadvantages in terms of bioavailability, onset, and duration of action.
CBD Oil (sublingual)
15–30 min.
Onset
4–6 hours
Duration
13–35 %
Bioavailability
CBD oil is placed under the tongue and held there for 60 to 90 seconds. The oral mucosa directly absorbs the CBD, bypassing the digestive tract and increasing bioavailability. This method offers the best balance between speed of action and duration of effect. Ideal for daily use and easy to dose.
See CBD oilsCBD Flowers (vaporizer / tea)
2–5 min.
Onset
2–3 hours
Duration
up to 56 %
Bioavailability
CBD inhaled via a vaporizer passes through the lungs directly into the bloodstream – the fastest method of consumption. Bioavailability is highest, and the effect occurs almost immediately. Infused as tea, the onset is slower (30–60 min.), as CBD is fat-soluble and requires adding a fat to the hot water. Ideal for occasional use.

30–90 min.
Onset
6–8 hours
Duration
6–15 %
Bioavailability
Capsules and edibles pass through the digestive tract and are metabolized in the liver (first-pass effect), reducing bioavailability. In return, the effect is more consistent and longer-lasting. Exact dosing is simple, and intake is discreet and tasteless. Ideal for a consistent and prolonged effect throughout the day or night.

The right CBD dosage is individual and depends on many factors. The principle "start low, go slow" has proven to be the best strategy.
Step-by-step dosage guide
Since everyone reacts differently to CBD, there is no universal dosage recommendation. Body weight, metabolism, severity of symptoms, and individual sensitivity play a role. The following guidance has proven effective in practice:
Start with a low dose of 10 mg of CBD per day, divided into 2 doses (morning and evening). With a 10% oil, this corresponds to 2–4 drops. Observe how your body reacts.
If the effect is not sufficient, gradually increase the dose by 5 mg per week. Allow at least 3–5 days between increases to assess the effect.
Once you feel the desired effect, you have found your optimal personal dose. For most people, it is between 20 and 60 mg per day. Some uses (e.g., for severe pain) may require higher doses.
Dosage by body weight
As a general guideline, body weight can serve as a reference. The following values provide a starting point – individual adjustment remains crucial:
Less than 60 kg
10–15 mg
Low
15–25 mg
Medium
25–40 mg
High
60–90 kg
15–20 mg
Low
20–35 mg
Medium
35–60 mg
High
More than 90 kg
20–30 mg
Low
30–45 mg
Medium
45–80 mg
High

Calculate CBD content per drop
A 10 ml bottle of CBD oil contains approximately 200 drops. With a 5% CBD oil (500 mg of CBD in total), each drop contains about 2.5 mg of CBD. With a 10% oil (1,000 mg of CBD in total), it's about 5 mg of CBD per drop. With a 20% oil, each drop contains about 10 mg of CBD. For beginners, it is recommended to start with a 5% or 10% oil, as the dosage can be adjusted more finely.
Common myths about CBD
Many half-truths and misunderstandings circulate about the effects of CBD. We unravel the most common myths with scientific facts.
Myth: "CBD gets you high and is a drug"
Fact: CBD is not psychoactive and does not cause intoxication. The WHO confirmed in 2017 that CBD does not have abuse potential. CBD products containing less than 0.3% THC are legal in France and are not classified as a drug. CBD modulates the endocannabinoid system without causing the consciousness-altering effects of THC.
Myth: "CBD works the same for everyone"
Fact: The effects of CBD are very individual and depend on many factors: body weight, metabolism speed, genetic configuration of cannabinoid receptors, method of consumption, dosage, and even gut microbiota composition. What works for one person at 20 mg may require 50 mg for another. This is why individual dose adjustment is crucial.
Myth: "CBD is a miracle cure for everything"
Fact: While CBD shows promising properties, it is not a panacea. Research is still in its early stages for many applications, and many results come from animal or in vitro studies. To date, CBD's efficacy is clinically established mainly for certain forms of epilepsy (Epidiolex approval). For other areas, there are promising indications but not yet definitive clinical proof.
Myth: "More CBD automatically means a better effect"
Fact: CBD follows an 'inverted U-shaped curve' (biphasic dose-effect relationship). This means that too little or too much CBD can be less effective than a moderate and optimal dose. A study by Zuardi et al. (2017) showed that 300 mg of CBD was more effective against anxiety than 150 mg or 600 mg. Finding the optimal dose is more important than simply increasing the amount.
Myth: "CBD oil and hemp oil are the same thing"
Fact: CBD oil and hemp seed oil are fundamentally different products. Hemp seed oil is pressed from hemp seeds and contains no CBD, but valuable omega-3 and omega-6 fatty acids. CBD oil is extracted from hemp flowers and leaves and contains concentrated cannabidiol. This confusion is unfortunately often exploited for marketing purposes.
Myth: "CBD is just a placebo effect"
Fact: Many double-blind controlled studies have demonstrated CBD's efficacy beyond the placebo effect – most clearly in epilepsy (Dravet syndrome, Lennox-Gastaut syndrome), where CBD reduced seizure frequency by 36 to 42% compared to placebo. Imaging techniques (fMRI) also show measurable changes in brain activity after CBD administration, particularly in the amygdala and prefrontal cortex.
