Healthy cannabis plant in soft natural light If you have searched “what is cannabis” or “whats cannabis,” you are not alone. Cannabis is surrounded by familiar terms, shifting laws, and plenty of myths. A clear starting point can make the subject feel much more approachable. At its simplest, cannabis is a genus of flowering plants in the Cannabaceae family. People have cultivated different cannabis varieties for thousands of years for fiber, seeds, food, aromatic compounds, and preparations containing cannabinoids. Today, cannabis may refer to a plant, a raw botanical material, or a wide range of products made from its flowers, extracts, and seeds. At Green Grove Bud, we see reliable information as the foundation of a stigma-free environment. Let’s break down the essential terms so you can understand cannabis, compare products thoughtfully, and make informed decisions within your local laws.

Cannabis sativa, Cannabis indica, and common plant labels

You will often hear cannabis described as Cannabis sativa, Cannabis indica, or a hybrid of the two. These names originally referred to differences in plant structure, geographic origin, growth patterns, and physical traits. For example, plants sold under the “sativa” label are often associated with taller growth and narrower leaves, while “indica” plants are often described as shorter and broader. However, the popular idea that sativa always feels energizing and indica always feels relaxing is too simple. Modern commercial cannabis has been extensively crossbred, and many products contain mixed genetics. The plant’s cannabinoid and terpene profile, potency, serving size, personal biology, and setting may influence the experience more than a broad label. For a science-backed overview of cannabis botany, Britannica’s cannabis plant reference is a useful starting point.

Hemp and marijuana: what is the difference?

Hemp and marijuana are not separate plant species in the everyday botanical sense. They are legal and commercial terms used to describe cannabis with different cannabinoid profiles and intended uses. Hemp generally refers to cannabis cultivated for fiber, seeds, oil, CBD, or other low-THC applications. In the United States, federal law has historically defined hemp around a limit of no more than 0.3% delta-9 THC by dry weight, although federal and state rules continue to evolve. Hemp can still contain cannabinoids and aromatic compounds, but hemp products made within applicable limits are generally not expected to create a THC-like high. “Marijuana” is a legal and common-use term for cannabis that exceeds applicable hemp THC limits or is cultivated primarily for intoxicating THC-rich flowers and extracts. The language and legal definitions vary by jurisdiction, and some people prefer terms such as “cannabis” or “adult-use cannabis.” Before buying, possessing, transporting, or growing any product, review current rules where you live. The Congressional Research Service’s hemp resources provide useful context on changing federal definitions.

What is cannabis flower?

Close-up cannabis flower with visible trichomes Cannabis flower, often called bud, is the mature flowering material of the plant. It is typically the part most concentrated in glandular trichomes: tiny structures that produce cannabinoids and terpenes. These trichomes give flower its distinctive appearance, aroma, and sticky texture. Flower may be smoked or vaporized, but the method matters. Smoking involves combustion, which creates smoke and irritants. Vaporizing heats cannabis without directly burning it, although vaping products still raise safety and quality questions, especially when they contain concentrates or unregulated additives. Hemp flower is also flower, but it comes from cannabis cultivated to meet hemp requirements and may be rich in CBD rather than THC.

Cannabinoids: THC, CBD, and more

Cannabinoids are chemical compounds produced by cannabis. The plant makes many cannabinoids, including THC, CBD, CBG, CBC, and others. Their concentrations can vary significantly between cultivars and products. THC, short for delta-9-tetrahydrocannabinol, is the primary intoxicating cannabinoid in most high-THC cannabis products. It can produce euphoria, altered sensory perception, relaxation, drowsiness, and changes in attention, memory, coordination, and reaction time. Higher doses may also bring unwanted effects such as anxiety, paranoia, or confusion. CBD, or cannabidiol, does not typically create the classic THC-like high. Non-intoxicating does not mean risk-free, though. CBD can interact with some medications, and product quality may vary. The U.S. Food and Drug Administration explains what it knows: and what remains uncertain: about cannabis-derived products, including CBD. Other cannabinoids are usually present in smaller quantities. Researchers are still studying how these compounds work individually and together. It is wise to treat claims about any cannabinoid as developing science rather than settled fact.

What are terpenes?

Terpenes are aromatic compounds found across nature, including in herbs, fruit, trees, and cannabis. They contribute to a product’s scent and flavor. Limonene is often associated with citrus aromas, pinene with pine-like notes, and myrcene with earthy or herbal aromas. Terpenes may influence how a cannabis product feels, particularly alongside cannabinoids, but the details are still being investigated. A terpene profile can help you describe and compare products, yet it should not be treated as a guaranteed effect label. “Pine-scented” does not automatically mean energizing, and “earthy” does not guarantee sleepiness.

The endocannabinoid system, explained simply

The endocannabinoid system, or ECS, is a signaling network found throughout the body. It includes endocannabinoids made by the body, cannabinoid receptors, and enzymes that help create and break down those signals. The ECS is involved in several physiological processes, including mood, appetite, memory, pain signaling, stress responses, and immune activity. Plant cannabinoids can interact with this system in different ways. THC can activate cannabinoid receptors, especially CB1 receptors in the nervous system, while CBD appears to influence several signaling pathways rather than producing the same direct receptor activity as THC. This does not mean cannabis is a universal treatment or that every product will affect everyone in the same way. It means the body has a complex biological system that helps explain why cannabinoids can influence perception, mood, appetite, and other experiences.

Common ways people consume cannabis

Cannabis products arranged for responsible-use comparison Cannabis products can be consumed through several routes:

  1. Inhalation: Smoking flower or vaporizing flower and concentrates can produce effects within minutes. The quick onset makes it easier to notice changes, but smoking exposes the lungs to combustion products, and high-potency concentrates can feel overwhelming.
  2. Edibles and drinks: Gummies, baked goods, capsules, and beverages pass through the digestive system. Effects may take 30 minutes to two hours: or longer: to appear and can last substantially longer than inhaled effects. Delayed onset makes it easy to take more before the first serving has fully taken effect.
  3. Sublingual products: Tinctures or oils held under the tongue may have a different onset from swallowed edibles. Always follow the product directions and check the amount per serving.
  4. Topicals: Creams, balms, and lotions are applied to the skin. They are generally intended for localized use and are not usually associated with a THC-like high, but product quality and evidence for specific outcomes vary. The route, dose, potency, personal tolerance, food intake, and other substances can all shape the experience. More product does not necessarily mean a better result.

Intoxicating and non-intoxicating effects

The word “intoxicating” describes effects that can alter perception, judgment, coordination, or consciousness. THC is intoxicating, while CBD is generally considered non-intoxicating in the THC-like sense. A product marketed as “hemp” or “CBD” may still contain measurable THC, so checking the label and independent testing information matters. A non-intoxicating product can still cause side effects or interact with medication. Likewise, a low-THC product can still affect someone who is sensitive to THC. Labels, serving sizes, and personal context are more useful than assumptions based on product names alone.

Responsible-use basics for newcomers

Important: Do not drive, cycle in traffic, operate machinery, or make safety-critical decisions after using THC. Avoid cannabis during pregnancy and breastfeeding, keep products locked away from children and pets, and speak with a qualified healthcare professional if you take medications or have concerns about mental health, heart health, or substance use. For adults who live somewhere cannabis use is legal, responsible habits include:

  • Start with a low amount and go slowly, especially with edibles.
  • Wait for an edible’s effects before considering more; delayed onset can lead to overconsumption.
  • Avoid mixing cannabis with alcohol or other intoxicating substances.
  • Choose products from regulated sources when available.
  • Keep original packaging and follow storage instructions.
  • Pay attention to THC and CBD amounts per serving, not only the total package amount.
  • Stop and seek help if severe confusion, chest pain, difficulty breathing, or other urgent symptoms occur. The CDC’s cannabis health information offers additional guidance on impairment, pregnancy, young people, and other health considerations.

How to read a cannabis product label

Hands reviewing a generic cannabis package and lab report A thoughtful label review can help you cultivate better habits. Look for:

  • The product type and total amount.
  • THC and CBD content, listed as a percentage or milligrams.
  • THC and CBD per serving for edibles, capsules, and beverages.
  • A batch number, expiration or packaging date, and manufacturer information.
  • Testing information, often called a certificate of analysis or COA.
  • Warnings about allergens, impairment, pregnancy, age limits, or medication interactions.
  • Screening information for contaminants such as pesticides, heavy metals, microbes, or residual solvents when available. Product labels are not equally reliable everywhere. Unregulated products may be inaccurately labeled or contain ingredients that are not disclosed. Treat health claims with caution: cannabis products are not automatically proven to prevent, treat, or cure a condition.

A clear foundation for understanding cannabis

So, what is cannabis? It is a diverse flowering plant genus that produces cannabinoids, terpenes, and other compounds. Cannabis flower, hemp, marijuana, THC, CBD, and product formats describe different parts of a larger picture: not interchangeable terms. As laws and research continue to evolve, the most useful approach is curious, practical, and evidence-minded. Check local regulations, compare labels, use lower-risk habits, and remain open to new findings.
