Hemp, cannabis, CBD and THC: understanding the essential differences

Definitions: hemp, cannabis, CBD and THC

Before delving into the scientific or legal details, it's essential to establish some simple definitions. Much of the misunderstanding surrounding CBD stems from an overly vague use of terminology. The term "cannabis" is often used to refer to an illicit drug, even though it also designates a plant. The word "hemp" is often used to refer to industrial varieties with low THC content. CBD and THC, however, are molecules, not plants.

Hemp

Hemp generally refers to varieties of Cannabis sativa L. cultivated for agricultural, industrial, food, textile, cosmetic, or wellness uses. These varieties are selected for their low THC content. Hemp can produce fibers, seeds, vegetable oil, hurds, plant proteins, and certain natural compounds such as cannabinoids.

Cannabis

The term cannabis refers to the Cannabis sativa L. plant in a broad botanical sense. In everyday language, it is often associated with varieties high in THC, used for their psychoactive effects. This dual meaning creates significant confusion: all hemp belongs to the Cannabis genus, but not all cannabis is necessarily a narcotic in the sense understood by the general public.

CBD

CBD, or cannabidiol, is a cannabinoid naturally present in hemp. It is primarily known for not producing the psychoactive effects characteristic of THC. CBD can be found in flowers, extracts, oils, cosmetics, or other products, the regulatory framework for which depends on their category.

THC

THC, or delta-9-tetrahydrocannabinol, is a psychoactive cannabinoid. It can alter perception, mood, alertness, coordination, and certain cognitive functions. This property explains its strict regulation. In France, THC remains a particularly closely monitored molecule.

CBD: scientific definition of cannabidiol.

Hemp and cannabis: the same botanical species?

Botanically, hemp and cannabis are often classified under Cannabis sativa L. This species encompasses various varieties, cultivars, and selections. The distinction between hemp and cannabis is therefore not solely botanical; it is also agricultural, chemical, regulatory, and cultural.

In the agricultural and industrial sectors, the word hemp is used to refer to varieties selected for their low THC content and productive uses. These uses include fibers, seeds, oil, insulation, paper, bio-based materials, and hemp-derived products. In everyday language, the word cannabis is more often associated with varieties high in THC.

The most important difference for the consumer is therefore not just the name of the plant, but its actual composition. A product derived from Cannabis sativa L. can be compliant or non-compliant depending on its THC content, origin, labeling, intended use, and applicable regulations.

Why is this distinction important?

This distinction helps avoid two common mistakes. The first is believing that all cannabis products are necessarily illegal. The second is believing that a product marketed as “natural” or “hemp-based” is automatically compliant. In reality, compliance depends on specific criteria, including the delta-9-THC level and the product category.

For a more historical and botanical perspective, see:
Hemp: history, botany and industrial uses.

Industrial hemp: an agricultural plant with multiple uses

Industrial hemp is an ancient crop. It has long been used to produce rope, textiles, paper, oil, food seeds, and materials. Its robustness, rapid growth, and diverse applications explain its historical and contemporary interest.

Today, hemp is once again at the center of many discussions for ecological, agricultural, and economic reasons. Its fibers can be used in bio-based materials. Its seeds are rich in nutrients. Its vegetable oil is used in food and cosmetics. Its flowers can naturally contain cannabinoids such as CBD.

Non-psychotropic uses of hemp

Industrial hemp should not be reduced to CBD alone. It is a versatile plant, used in several sectors:

• Textile: resistant natural fibers.
• Construction: hempcrete, insulation, bio-based materials.
• Diet: hemp seeds, hemp oil, vegetable protein.
• Cosmetics: vegetable oil, skin care, natural formulations.
• Wellness: products containing CBD under regulatory conditions.

This potential explains why hemp is often presented as a plant of the future. However, its development depends heavily on the legal framework and the ability of professionals to respect standards of quality, traceability, and transparency.

THC-rich cannabis: why is it strictly regulated?

Cannabis rich in THC is associated with psychotropic effects. THC acts on certain receptors in the central nervous system, which can alter perception, mood, coordination, attention, and short-term memory. These effects explain the strict regulation of THC in many countries.

In France, the distinction between CBD and THC is therefore fundamental. CBD must not be presented as recreational cannabis, and CBD products must not contain a THC level exceeding the applicable regulatory threshold. Conversely, a product rich in THC does not become legal simply because it also contains CBD.

The concept of a stupefying effect

The authorities are particularly interested in the presence of substances likely to have a narcotic effect. THC, being a psychoactive substance, occupies a central place in regulatory analysis. CBD, on the other hand, has been distinguished from THC by several decisions and opinions, notably because it does not have the same effect profile.

CBD: a non-psychoactive cannabinoid

CBD is often defined as a non-psychoactive cannabinoid. This means it does not produce the euphoric, altering, or intoxicating effects associated with THC. This difference has played a major role in the evolution of the European cannabidiol market.

CBD is generating scientific interest because it interacts with certain biological mechanisms, particularly the endocannabinoid system. However, it should not be presented as a universal remedy or a common over-the-counter medication. CBD products marketed outside of a pharmaceutical framework must adhere to responsible information guidelines.

Natural CBD, hemp extract and finished product

Several levels need to be distinguished. CBD is a molecule. Hemp extract is a preparation containing CBD and sometimes other compounds. The finished product is what the consumer finds on the market: oil, flower, resin, cosmetic, or other format. These three levels do not have exactly the same regulatory implications.

The World Health Organization has published a report on cannabidiol, often cited for its analysis of CBD's profile:
Read the World Health Organization report on cannabidiol.

THC: the psychoactive molecule in cannabis

THC is the main cannabinoid responsible for the psychoactive effects of cannabis. Its action on the central nervous system explains the sensations of euphoria, altered perception, and possible impairment of psychomotor skills. It is precisely this profile that distinguishes it from CBD.

THC can also pose safety risks, particularly regarding driving, alertness, addiction, and mental health in certain individuals. Therefore, serious content must avoid trivializing the issue and emphasize that THC is not subject to the same regulations as legal CBD.

Why is the THC threshold so important?

The regulatory threshold allows for the differentiation between compliant and non-compliant hemp products. In France, the decree of December 30, 2021, stipulates that the delta-9-THC content of hemp extracts and products containing them must not exceed 0.30%. Official source:
Decree of December 30, 2021, on Légifrance.

CBD vs THC: a complete comparison chart

The following table provides a quick overview of the main differences between CBD and THC. It does not replace a complete legal or scientific analysis, but it helps to understand why these two molecules should not be confused.

The frequent confusion surrounding CBD, hemp, and cannabis

Confusion surrounding CBD is widespread. It often stems from a mix of botanical terminology, common usage, and regulations. To improve the quality of information, these errors must be corrected without oversimplifying.

Mistake #1: Thinking that CBD and cannabis are synonymous

CBD is a molecule. Cannabis is a plant. A plant can contain CBD, THC, and other compounds. Therefore, it is incorrect to say that CBD and cannabis are the same thing.

Mistake #2: believing that natural automatically means legal

A natural product can be non-compliant if its composition, labeling, or use does not meet regulations. Hemp is natural, but that alone is not enough to guarantee the compliance of a finished product.

Mistake #3: believing that CBD is necessarily THC-free

Some CBD products may contain trace amounts of THC within legal limits. This distinction is important, particularly for driving, drug testing, and sensitive individuals.

Mistake #4: Presenting CBD as a medicine

CBD should not be presented as a treatment in content intended for the general public. Unauthorized medical claims can mislead readers and pose a regulatory problem.

Mistake #5: Confusing the absence of psychotropic effects with a total lack of alertness

The fact that CBD is not psychoactive like THC does not mean that all CBD products are suitable for everyone. Drug interactions, product quality, and the possible presence of trace amounts of THC must be taken seriously.

Legal framework in France: what you need to understand

In France, CBD is permitted under certain conditions. The regulatory framework is based in particular on the origin of the hemp, the delta-9-THC content, the product category, and how it is presented. Therefore, simply displaying the word CBD is not enough to guarantee that a product is compliant.

The decree of December 30, 2021 specifies that the delta-9-THC content of hemp extracts and products containing them must not exceed 0.30%. This rule is central to understanding the French CBD market:
Consult the decree of December 30, 2021 on Légifrance.

CBD flowers and leaves: decision of the Council of State

The French Council of State has overturned the general and absolute ban on the sale of cannabis flowers and leaves without intoxicating properties, provided their THC content remains below the regulatory threshold. This decision marks an important step in clarifying the French legal framework:
Read the Council of State's decision on CBD flowers and leaves.

The 0.30% threshold is not a guarantee of safety

It is important to understand that the 0.30% threshold is a regulatory limit, not a guarantee that all uses are risk-free. The Council of State has also reiterated that this threshold is not a safety threshold, while deeming the blanket ban on flowers and leaves with low THC content disproportionate. This distinction is essential for responsible consumer information.

To consult the full legal decision:
Decision of the Council of State of December 29, 2022 on Légifrance.

European framework: why the CJEU played an important role

European law has strongly influenced the evolution of the CBD framework. The judgment of the Court of Justice of the European Union in case C-663/18 is regularly cited, as it helped to distinguish CBD from narcotics in the context of EU law.

This legal precedent does not mean that all CBD products are automatically authorized everywhere and in all forms. Rather, it serves as a reminder that national restrictions must be justified, proportionate, and compatible with European law.

CBD in food: beware of Novel Food

Food products containing CBD or certain hemp extracts may fall under the Novel Food category. This is a separate issue from the simple THC threshold. A product may meet the THC threshold but still raise other regulatory questions depending on its form, use, and labeling.

To consult the Novel Food catalogue:
European Commission Novel Food Catalogue.

Quality, analysis and consumer safety: why the CBD/THC distinction is essential

The distinction between CBD and THC is not merely theoretical. It has concrete consequences for the consumer. A product that is mislabeled, misanalyzed, or misformulated may contain a different level of cannabinoids than advertised. This is why laboratory analysis, traceability, and transparency are essential.

A study reported by MILDECA showed that the composition of many CBD products can differ from that indicated on the label. This information underscores the importance of choosing regulated products and not relying solely on marketing claims:

Analyses to look for

Useful analyses may include:

• the CBD level;
• the THC level;
• the complete cannabinoid profile;
• pesticide testing;
• the search for heavy metals;
• the search for residual solvents;
• the search for molds or microbiological contaminants.

Consumers must have access to understandable information. A reputable product should allow consumers to verify its batch, composition, and compliance. In a responsible approach, transparency should not be a vague marketing ploy, but concrete proof.

CBD, THC and driving: essential caution

Driving is one of the most sensitive issues surrounding CBD. Even when a product complies with the law, it may contain traces of THC within the permitted limits. THC can be detected during roadside checks. This means that CBD users must be cautious, even if they are using a product marketed as compliant.

CBD should therefore not be presented as a guarantee of risk-free driving. Responsible communication involves reminding people that the legality of a product and the results of a roadside drug test are two separate issues. People who drive regularly, hold positions of responsibility, or are subject to testing should be particularly vigilant.
