CBD Receptivity: individual characteristics

CBD Receptivity: individual characteristics

01/08/2023

Cannabidiol (CBD) possesses a wide range of proven therapeutic properties. Research demonstrates its effectiveness in reducing anxiety, inflammation, and epileptic seizures, as well as its utility in treating certain psychiatric disorders, including schizophrenia [1]. Additionally, CBD is known as an antioxidant and neuroprotector, making it a promising substance for long-term nervous system support.

Due to the absence of psychoactive properties and minimal side effects, cannabidiol is generally considered safe for most people. However, the reaction to CBD can vary significantly from person to person [2]. Some experience a noticeable effect even at low doses, while others require much larger amounts or a longer course of use. Let’s examine the key factors behind why this happens.

1. Choosing the Right Form

CBD is available in various forms:

Capsules;
Oil;
Vapes;
Gummy candies;
Creams and ointments.

Oil remains the most in-demand option among all variants [3;5]. In this context, not only the cannabidiol itself plays a vital role, but also the carrier oil in which it is dissolved. The carrier oil significantly affects CBD absorption. While manufacturers use coconut, hemp, or sesame oil, MCT oil is considered the most effective.

MCT (medium-chain triglycerides) consists of fats that dissolve faster and differently than regular fats—primarily in the stomach rather than the intestines [4;6]. This mechanism helps stabilize CBD molecules and reduces their breakdown during digestion before they enter the bloodstream [5;7]. As a result, the bioavailability of cannabidiol increases, and the effect can be more pronounced.

2. Sufficient Concentration and Dosage

One of the main reasons for individual differences in CBD's effect is the dosage. In scientific studies, cannabidiol is applied across an incredibly wide range: from 15–30 mg per day to 1,000–1,500 mg per day [6;3].

In clinical practice, particularly when treating epilepsy in children, the dosage is often calculated individually based on body weight (approximately 5–20 mg/kg) [7;4]. This emphasizes once again that there is no universal "correct" dose.

For one person, 20 mg may be entirely sufficient, while another may not feel any changes even at a much higher dosage. Therefore, the effectiveness of CBD directly depends on selecting the amount that corresponds to a specific organism.

3. Physiological Characteristics

The effective absorption of CBD depends on the metabolic characteristics of each individual. This process is influenced by many factors: body mass index (BMI), sex, frequency and duration of use, and the method of administration [8].

For example, the bioavailability of CBD when taken orally as an oil is about 6%, whereas through inhalation (vaping), it can reach 30% [9]. The half-life also varies—it can range from one hour to several days and usually increases with long-term regular use [10].

Differences have also been recorded between men and women. After a single dose, men tend to clear cannabidiol from the body faster, whereas in women, it accumulates more actively due to a higher percentage of adipose (fat) tissue. After a long-term course (>5 weeks), CBD levels in a woman's blood plasma can remain detectable for over 50 days [11].

4. Increased Sensitivity to CBD

Some individuals exhibit high individual sensitivity to cannabidiol [12]. This means that even small doses of CBD can cause more intense side effects than for the majority of users. Most often, this manifests as:

Diarrhea or mild gastrointestinal upset;
Drowsiness or increased fatigue;
Changes in appetite and weight;
Increased sensitivity to stressors or heightened anxiety (if consumed in excess).

To avoid these consequences, the most effective approach is the gradual introduction of CBD into your routine. It is best to start with a minimum dose of 15–30 mg per day. After several days or weeks, you can cautiously increase the amount while assessing your body's reaction. This not only reduces the risk of side effects but also helps determine your personal optimal dose for achieving the desired therapeutic effect.

Choosing CBD for Yourself

The individual effect of CBD is a natural characteristic, not an anomaly. The reaction to cannabidiol is shaped by a complex combination of factors; therefore, the successful and safe use of CBD begins not with high expectations, but with a careful approach. Start with a minimal dose, observe the effect, consider your own sensitivity, and gradually find your optimal amount.

Regular but moderate use allows for a cumulative effect—stabilizing sleep, reducing anxiety, easing pain, and supporting the nervous system.
