Cannabis is the plant; hemp and marijuana are two kinds of the same species, Cannabis sativa L. Hemp is grown for fibre, seed and CBD and must stay under a legal THC limit (0.3% in EU farm rules). Marijuana is bred for high THC, the compound that causes intoxication. The two also differ genetically.
Views on cannabis are shifting. Many people are unsure about the difference between cannabis, marijuana and hemp. These terms are often used together, but they have different meanings.
Laws and industry discussions show how complex these differences can be. There are specific rules for controlled and medical use in many regions. Understanding cannabis classification is important for interpreting regulations and product categories.
Formula Swiss has sold hemp-derived products to 62 countries, and the same confusion comes up in almost every market. Cannabis, marijuana and hemp mean different things, and each term has its own history and legal status.

The fundamentals of cannabis classification
Understanding how cannabis is classified is essential to recognising its diverse applications. Cannabis sativa is notable for its broad range of uses, although its recognition varies across different regions.
Understanding the Cannabis sativa species
Cannabis sativa is a botanical species that includes hemp and plants commonly called marijuana. Plant height and leaf shape vary, so appearance alone cannot establish cannabinoid content or legal classification.
Cannabis sativa is known for its wide range of strains, each with varying concentrations of THC and CBD. These differences allow for diverse applications and align with distinct industry standards.
Key components of cannabis plants
Cannabinoids are the key parts of cannabis plants. THC and CBD are the most well-known cannabinoids. THC is linked to psychoactive effects, while CBD is known for its non-intoxicating profile.
Cannabis contains more than 100 identified cannabinoids among over 560 known constituents (ElSohly et al., 2017). These differences continue to drive scientific research.
Learning about these basics shows how complex cannabis classification is. It also points out the key differences between the parts and types of cannabis, such as Cannabis sativa. Clear classification supports regulators, researchers and legal authorities.
Defining cannabis
Cannabis is a genus in the Cannabaceae family. Kew’s Plants of the World Online accepts Cannabis sativa as a species and treats several other cannabis names as synonyms. Botanical names, commercial strain labels and legal categories serve different purposes; they should not be treated as interchangeable classifications.
Understanding the differences between cannabis plants supports their cultivation, classification and broader industry considerations. Varieties with low THC content are typically used for industrial purposes, while those with higher THC levels are handled differently depending on local practices.
As discussions around cannabis continue, understanding how the plant is classified is valuable for the public, industry professionals and policymakers.
Marijuana: psychoactive varieties of cannabis
Marijuana comes from the Cannabis sativa plant and is known for its psychoactive effects. These effects come mainly from THC (tetrahydrocannabinol). THC produces the high associated with marijuana and contributes to the varying effects of different strains.
The focus on marijuana is on its psychoactive potential. This sets it apart from other cannabis types that are associated with cannabinoids such as CBD.
Characteristics of marijuana strains
Marijuana strains can differ in aroma, appearance and cannabinoid composition. Colour or smell alone does not establish THC potency; a measured cannabinoid profile is needed for a reliable comparison.
People involved in cultivation or trade often look for strains that meet specific needs or preferences. The wide selection of available strains supports numerous product categories suited to varying market demands across different areas.
The role of THC in marijuana
THC is the primary psychoactive component of marijuana. It interacts with the body's endocannabinoid system. This interaction can affect mood, perception and sensory response, and is often associated with euphoria or relaxation.
Understanding THC and its characteristics contributes to the broader understanding of the cannabis plant. Ongoing research continues to investigate the functions of THC and other cannabinoids within structured industry settings.
Hemp: the industrial powerhouse
Industrial hemp has applications in textiles, composite materials and construction. Its suitability and environmental performance depend on the plant material, the manufacturing process and the requirements of the finished product.
Uses of industrial hemp
Industrial hemp is used in products such as paper, rope and building materials such as hempcrete. Hemp seeds and oils are also applied in areas such as cosmetics and personal care items, reflecting its diverse potential.
CBD content in hemp
Hemp varieties have different cannabinoid profiles. A low-THC classification does not guarantee a high CBD concentration. The composition of a particular crop or extract needs to be established by suitable testing.
Key differences between cannabis, marijuana and hemp
Recognising the differences between cannabis, marijuana and hemp is essential. Each has distinct characteristics based on chemical composition, intended use and how they are categorised across various contexts.
THC and CBD profiles: a comparative view
Cannabis varieties differ in THC and CBD content. Higher THC levels are associated with intoxicating effects, while low-THC hemp is used in several industries. In EU agricultural rules, hemp means approved Cannabis sativa varieties whose THC content does not exceed 0.3% (European Commission). Other countries set their own limits, and a low-THC classification says nothing about CBD content.
Agricultural and practical distinctions
Hemp and marijuana are cultivated with different goals in mind. Hemp is primarily grown for applications such as textiles, bio-based materials and industrial products, usually on a larger scale and with low THC content. Marijuana cultivation focuses on enhancing THC levels and often involves more specialised growing techniques.
Hemp is commonly regarded as an industrial resource in many regions, with its usage shaped by its composition and practical benefits. Marijuana, due to its psychoactive profile, is managed differently, influencing its availability and applications.
| Cannabinoid | Marijuana | Hemp |
|---|---|---|
| THC | High | ≤0.3% THC (EU) |
| CBD | Variable | Variable; testing required |
| Recognition | Controlled in many areas | Widely accepted for industrial use |
The psychoactive effects of THC
THC affects mental and sensory responses and can produce intoxication. CBD is generally described as non-intoxicating, but it can still affect the brain and body; non-intoxicating does not mean inactive or free of risk.
Distinguishing psychoactive properties
When THC interacts with cannabinoid receptors in the brain, it activates a series of neural pathways. This can affect perception, mood and cognition. THC can influence several brain systems involved in memory, coordination, perception and reward.
THC-rich cannabis and low-THC hemp differ in their cannabinoid profiles. The concentration in a particular plant or finished product must be measured; a general category is not a substitute for testing.
| Substance | THC content | Psychoactive effect |
|---|---|---|
| Marijuana | Variable; use the measured THC concentration | Can cause intoxication; effects vary with composition and exposure |
| Hemp | ≤0.3% THC (EU) | Effects depend on the actual composition and product |

Cannabis cultivation and strain development
Modern cannabis cultivation and strain development combine traditional horticulture with new techniques. This includes improvements in aroma, appearance and cannabinoid profiles across Cannabis sativa strains.
Advanced strain development methods also support the creation of Cannabis sativa strains for defined uses. These modern approaches expand beyond traditional techniques. They reflect a focus on selective cultivation and sustainability in cannabis-related agriculture.
Cultivation and strain selection can support more consistent production of Cannabis sativa, but genetic identity alone does not establish the quality of the harvested material. Crop conditions, plant health and suitable testing also need attention.
CBD: a generally non-intoxicating cannabis component
CBD is a prominent compound found in cannabis and is generally described as non-intoxicating. It differs from THC, which can produce a high. CBD can nevertheless have biological effects and interact with medicines, so this distinction should not be interpreted as a guarantee of safety.
CBD in cannabis products
Considerations and possible reactions:
- It is advisable to consult a medical professional before introducing CBD alongside other medications. See our guide to CBD and medication.
- Some individuals may experience mild effects such as dry mouth, tiredness or stomach discomfort. See our guide to CBD side effects.
- When choosing a CBD product, look for clear labelling, a lab report for the batch you are buying, and a producer that tests every batch.
Interest in CBD continues to grow. Ongoing research is contributing to the expanding understanding of its characteristics and the forms in which it may be used across non-intoxicating applications.
Industrial applications of hemp
Hemp supplies fibre, seeds and other raw materials for manufacturing. Hemp fibres are used in textiles, hurds in building materials such as hempcrete, and hemp-derived ingredients in bio-based plastics. Hemp seed and its oil are used in food and in cosmetics. Analysis of hemp seed oils has found THC, CBD and some 30 other cannabinoids at trace levels (Citti et al., 2019).
Frequently asked questions
What is the difference between cannabis, marijuana and hemp?
Cannabis sativa L. includes both hemp and varieties commonly called marijuana. Hemp is bred for low THC; in EU agricultural rules it may contain no more than 0.3% THC. Marijuana is bred for high THC. Other countries set their own limits.
What is marijuana used for?
Marijuana commonly refers to cannabis grown for its THC-rich flowers and their intoxicating effects, in medical programmes and, where permitted, in regulated recreational markets.
What is hemp used for?
Hemp is cultivated for its fibre, seeds and other outputs, and is used in textiles, construction materials, plastic composites and personal care formulations. It is associated with low-THC plant classifications; CBD content varies and should not be inferred from that classification alone.
What is the difference between marijuana and hemp seeds?
Both seed types originate from Cannabis sativa L. The distinction concerns the variety and the crop it can produce. The seeds themselves contain very little THC or CBD; traces come mainly from contact with resin during harvesting and processing, and lab analysis of hemp seed oils has found trace cannabinoids (Citti et al., 2019).
Can hemp be used for building materials?
Yes, hemp can be processed into materials such as hempcrete, insulation and other construction-grade alternatives.
Is there a difference between the chemical composition of hemp and marijuana?
Yes. A study of 124 samples found that hemp and marijuana differ across the whole genome, not only in THC genes; hemp was closer to "indica"-type marijuana than to "sativa" types (Sawler et al., 2015). Hemp's dominant cannabinoid is usually CBDA, made by the enzyme CBDA synthase (Taura et al., 2007).
Can hemp be used as a biofuel?
Yes. Hemp can be converted into biodiesel and ethanol. Its oil and cellulose components are useful in renewable fuel production.
How do the cultivation methods differ between hemp and marijuana?
Fibre and grain hemp are often field crops, while flower production may use fields, greenhouses or indoor facilities. Planting density, crop care and harvest methods depend on the intended output and conditions.
