Cannabis

Cannabis is a genus of plants belonging to the Cannabaceae family. Cultivated for several thousand years, it has been part of the history of many civilisations through its agricultural, textile, food, industrial and, more recently, scientific uses. Depending on the varieties cultivated and the objectives pursued, cannabis may be used for its fibres, seeds or compounds naturally present in its flowers.

Cannabis is characterised by a particularly rich chemical composition. The plant produces several hundred natural molecules, including cannabinoids, terpenes and flavonoids. This diversity contributes to the characteristics of each variety, whether in terms of its aromatic profile, chemical composition or botanical properties.

A plant cultivated for thousands of years

The earliest evidence of cannabis cultivation dates back several thousand years. Historically, the plant has been used in many regions of the world to produce textile fibres, ropes, paper and sails. Its seeds have also been used as food for humans and animals.

Over the centuries, selection, cultivation and processing techniques have improved, giving rise to many modern uses. Today, cannabis is present in sectors as varied as bio-based materials, cosmetics, food, wellbeing and scientific research.

A plant with a complex composition

Cannabis naturally produces more than one hundred identified cannabinoids. Among the best known are CBD, THC, CBG, CBN, CBC, CBDA and CBGA. These molecules are synthesised mainly in the trichomes, tiny resin glands found on the flowers.

The plant also produces many terpenes, which account for a large part of its characteristic aromas. Compounds such as myrcene, limonene, pinene, linalool, humulene and caryophyllene contribute to the aromatic diversity observed among different varieties.

These compounds are joined by flavonoids and many other plant molecules that contribute to the chemical richness of cannabis.

Great genetic diversity

Today, cannabis encompasses a very large number of genetic lines developed through selections made by growers over time. This work makes it possible to obtain plants with different characteristics in terms of growth, yield, morphology, aromas or composition.

The terms indica, sativa and hybrid are commonly used to describe certain genetic lines or their genetic origin. Other classifications, such as photoperiodic or autoflowering varieties, describe their development pattern more specifically.

Cultivation and production

Cannabis can be cultivated using different methods, such as indoor, outdoor or greenhouse cultivation. Each technique has its own characteristics and influences the plant's growing conditions.

Final quality depends on many parameters, including genetics, substrate, nutrition, lighting, climate, harvesting, drying, curing and the storage methods used after production.

Cannabis today

Today, cannabis occupies an important place in many areas of research. Botanists, agronomists, chemists and biologists study its genetics, composition, development mechanisms and the various molecules it naturally produces.

Thanks to its genetic diversity, chemical richness and numerous applications, cannabis remains one of the most studied and versatile plants in the plant kingdom.
