What Is Cannabis: Product Category Basics

Cannabis is a plant, and a licensed California dispensary sells that plant in eight main product categories: flower, pre-rolls, vapes, concentrates, edibles, beverages, tinctures and topicals. Each category holds cannabis in a different physical form, and the form changes how a product is used and how soon its effects may begin. This page defines all eight so you can tell them apart across different formats.

Key facts

Eight categories: flower, pre-rolls, vapes, concentrates, edibles, beverages, tinctures and topicals.
Four are commonly inhaled, three are taken orally, and one is applied to the skin. Tinctures can also be used under the tongue as labeled.
Inhaled products take effect within minutes. The CDC describes edible onset as 30 minutes to 2 hours; full effects can take longer.
Cannabis contains cannabinoids such as THC and CBD, as well as aromatic compounds called terpenes.
California adult-use purchases require age 21 or older and valid identification. Medicinal purchases require age 18 or older and the required medical documentation.

What cannabis is, and what a dispensary sells

Cannabis is a flowering plant whose harvested and processed parts are sold as consumer products. The CDC’s definition includes its dried flowers, leaves, stems and seeds. At a dispensary, cannabis may be sold as cured plant material or processed into another form.

Two families of compounds appear throughout the menu. Cannabinoids include THC and CBD: THC can produce intoxication, while CBD by itself does not produce a high. Terpenes are aromatic compounds that contribute to smell and flavor. Flower and ordinary pre-rolls retain the plant material; extracts and infused products use compounds separated from it.

The plant and the product category are different things. Processing changes the form, the unit it is sold in, and the way it is used. A gram of flower and a gram of concentrate may come from the same crop, but they are not interchangeable products.

Two things separate one cannabis category from another

Form determines how a product is used

Form describes what is physically inside the package. Dried plant material, oil in a sealed cartridge and a gummy each require a different approach. Form also determines what equipment is needed, which is why a concentrate and an edible sit in different parts of the menu.

Onset determines how a person plans around it

Onset is the time between using a product and first noticing an effect. Inhaled cannabis enters through the lungs and can act within minutes. Swallowed products pass through the digestive system. The CDC describes 30 minutes to 2 hours for edible effects to begin; this is a general range, not an absolute upper bound. Full effects can take longer.

Delayed onset can lead people to consume more before the first serving takes effect. Product formulation, food, and individual differences all matter. Under-the-tongue tinctures are an exception to treating all oral products as swallowed products.

The four inhaled categories

These categories are commonly inhaled and share a comparatively fast onset. Their preparation and equipment differ.

Flower

Flower is the dried and cured bud of the cannabis plant, sold as loose plant material. It is ground and smoked in a pipe, water pipe or rolling paper, or used in a dry herb vaporizer. Effects can begin within minutes.

Flower is sold by weight, commonly as an eighth at 3.5 grams, a quarter at 7 grams, a half ounce at 14 grams, or an ounce package labeled around 28 grams. The label gives the cannabinoid content for that batch. The cannabis flower guide explains weights and product selection.

Pre-rolls

A pre-roll is flower already ground and rolled into a paper cone or tube. It is flower in a finished format, with an onset within minutes when smoked. Pre-rolls come individually or in packs, often in sizes from 0.5 to 1 gram, with other sizes available. Infused pre-rolls add concentrate and may contain more THC. Ordinary pre-rolls do not require a grinder, rolling papers or a vaporizer.

Vapes

A vape contains cannabis oil in a cartridge, an all-in-one pen or a pod, heated by a battery instead of burned. Common formats include 510-thread cartridges, disposables with built-in batteries, and proprietary pods such as STIIIZY. Cartridge and pod sizes often include 0.5 and 1 gram.

The oil may be distillate, live resin or live rosin. Both oil formulation and compatible hardware matter. Effects can begin within minutes when inhaled. The cannabis vape guide explains the formats and oil types.

Concentrates

Concentrates separate or extract resin from cannabis plant material. The category includes live resin, live rosin, wax, badder, shatter, THCA diamonds, hash and kief. Concentrations vary substantially; check the batch label. THCA and THC are different measurements, so a THCA percentage should not be treated as an identical THC percentage.

Many concentrates are sold in 1 gram containers and used with a compatible dab rig, electronic rig or vaporizer, or added to flower. When inhaled, effects can begin within minutes. The concentrates guide explains extraction methods and textures.

The three oral categories

Edibles, beverages and tinctures are taken by mouth. Swallowed products generally have a slower onset than inhaled products; tinctures used under the tongue follow their own product instructions.

Edibles

Edibles are cannabinoid-infused foods such as gummies, chocolates, chews and baked goods; swallowed capsules are often grouped with oral products. Labels list milligrams per serving and per package, so check both rather than assuming the whole package is one serving.

The CDC gives a general onset of 30 minutes to 2 hours. Health Canada describes oral effects lasting about four to eight hours, with variation and possible lingering impairment. See the edibles guide for formats and labeling.

Beverages

Beverages include infused seltzers, sodas, teas and drink mixes. They are labeled in milligrams per serving and container. Swallowed drinks follow oral onset patterns, while some formulations are marketed as faster acting. Follow the particular label rather than assuming every drink works at the same speed. The serving unit is a drink, which is why the menu gives beverages their own section.

Tinctures

A tincture is liquid cannabis extract in an oil or alcohol base, commonly sold with a dropper or metered pump. The label gives milligrams per bottle and serving. A marked dropper helps measure the stated serving; it does not make every tincture more precise than all other formats.

Depending on the instructions, tinctures may be held under the tongue or swallowed, including in food or drink. Those routes and the formulation affect onset. Swallowed tinctures follow oral timing; do not assume immediate effects from under-the-tongue use. They require no inhalation or vaporizer.

Topicals, the category applied to the skin

Topicals include infused lotions, balms, salves, oils and bath products. Transdermal patches may also be stocked in this section, but they are designed differently from ordinary surface creams and may have systemic effects. Read each product’s intended use, cannabinoid content and directions. There is no single onset window that applies to every topical or patch.

Accessories are on the menu and are not a cannabis product category

Batteries, grinders, papers, glass and rigs are equipment rather than cannabinoid products. Some vapes and concentrates need a separate compatible device; all-in-one pens already include a battery. Check compatibility before choosing hardware.

The eight categories side by side

Product form, use, onset and labeling
Category	Physical form	How it is used	Onset	How it is sold
Flower	Dried, cured buds	Smoked or used in a dry herb vaporizer	Within minutes	By weight: commonly 3.5 g, 7 g, 14 g or 28 g
Pre-rolls	Ground flower rolled in paper	Smoked as sold	Within minutes	Singly or in packs; sizes vary
Vapes	Oil in a cartridge, disposable pen or pod	Heated by a compatible battery and inhaled	Within minutes	Commonly 0.5 g or 1 g units; other sizes exist
Concentrates	Extracted or separated cannabis resin	Vaporized with compatible equipment or added to flower	Within minutes when inhaled	By weight, often 1 g
Edibles	Infused food or capsules	Eaten or swallowed	Often 30 minutes to 2 hours; full effects can take longer	Milligrams per serving and package
Beverages	Infused drinks and drink mixes	Drunk	Often 30 minutes to 2 hours; formulation matters	Milligrams per serving and container
Tinctures	Liquid extract in a dropper or pump bottle	Taken under the tongue or swallowed as labeled	Depends on route and formulation; swallowed products follow oral timing	Milligrams per serving and bottle
Topicals	Infused lotion, balm, patch, oil or soak	Applied to the skin as labeled	Product-dependent; follow the label	Milligrams per container or unit

Where strain names and indica, sativa and hybrid fit

Strain names describe the variety a product came from; product categories describe its form. A single strain can appear as flower, pre-rolls and extracted oil. Indica, sativa and hybrid are labels at the plant and strain level, not a description of which product category you are holding.

Those labels are a starting point rather than a prediction. Cannabinoid content and terpene profiles can vary by grower, product and batch. Explore the Atrium strain library and Indica vs Sativa vs Hybrid: What the Labels Actually Mean.

Compare the numbers within a category first. Flower and concentrates commonly show percentages; edibles, beverages and tinctures show milligrams per serving and package. A 10 milligram edible and a 1 gram cartridge are not directly comparable serving units.

What every category has in common at a licensed dispensary

The California Department of Cannabis Control requires retailers to be licensed and to sell cannabis goods that have passed testing and quality assurance review. Packaging provides required product and cannabinoid information, with batch identification connecting a product to its testing records.

Adult-use customers must be 21 or older. Medicinal customers must be 18 or older with the required physician’s recommendation or medical marijuana identification card. Retailers verify identity using accepted government-issued photo identification, such as a driver’s license, passport or military ID. The California DCC describes these eligibility and identification requirements.

Testing and labeling requirements apply to cannabis goods, not accessories such as empty batteries or grinders. A passing test is not a guarantee that cannabis is risk-free or suitable for every person.

What this page does not cover

This page defines product formats. It does not prescribe a product or a dose.

Medical questions and interactions with medications belong with a qualified health professional.
Onset and duration vary between people and products.
Potency is not a quality ranking. A higher THC number does not automatically make a better fit.

The Cannabis 101 library covers the how and why behind these formats.

Frequently asked questions

What are the main types of cannabis products?

This guide groups the menu into eight categories: flower, pre-rolls, vapes, concentrates, edibles, beverages, tinctures and topicals. Four are commonly inhaled, three are taken orally, and one is applied to the skin. Tinctures may also be taken under the tongue as labeled.

What is the difference between cannabis flower and concentrates?

Flower is the dried, cured bud with its plant material intact. Concentrates separate or extract the resin and can contain substantially higher cannabinoid concentrations. Both are sold by weight. Read the current batch label rather than treating a potency range as a quality grade.

Why do edibles take longer to work than a vape or a pre-roll?

Inhaled cannabis enters through the lungs; swallowed cannabis passes through the digestive system. The CDC describes an edible onset of 30 minutes to 2 hours. Full effects may take longer, and effects can last several hours. Two hours is not a guaranteed deadline for every product or person.

Do indica, sativa and hybrid describe the product or the plant?

They are plant and strain classifications used as retail labels. One strain can be sold as flower, a pre-roll or a concentrate, so the type label does not identify the product format or guarantee an effect.

Are all the products in a licensed dispensary tested?

California requires licensed retailers to sell cannabis goods that have passed testing and quality assurance review. Accessories such as batteries and papers are not cannabis goods. Batch testing does not mean cannabis is risk-free.

What age restrictions apply in California?

California permits adult-use cannabis purchases for adults 21 and older. Medicinal purchases require age 18 or older and the required medical documentation. Licensed retailers must verify identity and eligibility.
