Most consumers focus on the THC percentage, but a vape cartridge actually contains much more than just the cannabis oil.
This article is a transparency guide for smart buyers and retailers, covering the cannabis oil itself, cannabinoids and terpenes, the hardware components, and potential additives and contaminants that can occur with low-quality cartridges.
Let’s break down all the components of a cannabis vape cartridge so you know exactly what you are using or selling!
RELATED: How to Tell if Your Vape Cart is Real or Fake
What’s In Your Cannabis Vape Cartridge? First, the Cannabis Oil
These are the most obvious things you’ll see on your vape cart: the Cannabis Oil (what you inhale), and the Hardware (what makes it work).
Both oil and hardware quality can affect the safety, performance, and overall experience of using a cannabis vape cart.
The most obvious content of your vape cart is the cannabis oil. This is the core substance that vaporizes, and you inhale.
Cannabis oil determines the potency, flavor, and effects of vaping a cart. The higher the quality, the smoother and more pleasant every hit will be.
Cannabinoids and Terpenes are what typically comprise a cannabis oil.
Cannabinoid
Cannabinoids are the active compounds extracted from the cannabis plant that bind to the receptors of the body’s endocannabinoid system, which causes the effects users get from using a cannabis cart.
The primary extracts are Tetrahydrocannabinol (THC), which gives the psychoactive effect, and Cannabidiol (CBD), which gives the therapeutic, non-intoxicating effect.
But apart from these two, other minor cannabinoids can also be extracted from a cannabis plant, such as:
- CBG (Cannabigerol): Known for potential therapeutic benefits and often found in higher concentrations in specially developed strains.
- CBN (Cannabinol): A common, mildly psychoactive degradation product of THC often used for sleep.
- CBC (Cannabichromene): Researched for its potential anti-inflammatory and mood-enhancing properties.
These can also be found inside your cannabis vape cartridge, though in small amounts only. However, they are still recognized for their contribution to the vape product's overall effect.
Another important thing to know is the THC percentage, which indicates the potency of the psychoactive or therapeutic compounds in your cannabis oil.
The higher the THC percentage is, the stronger and more intense your “high” will be. But depending on the CBD to THC ratio, your cannabis oil can also offer a blend of therapeutic relief with a mild and functional psychoactivity.
You can check this on your vape cart’s Certificate of Analysis (COA).
Terpenes
If cannabinoids produce the effect, terpenes are responsible for the taste and scent, which can influence user experience.
They are aromatic organic compounds found in most plants that define the taste, smell, and overall effect. They are also used as natural thinners that improve the oil's viscosity and vaporization.
Terpenes can be derived from a cannabis plant itself or from a different plant.
Cannabis-Derived Terpene (CDT) is extracted directly from the cannabis or hemp plant and provides a highly authentic and strain-specific smell and taste.
Depending on the dominant terpene, your vape cart can have different notes of taste and smell:
- Myrcene-dominant - Earthy/ Musky
- Limonene-dominant - Citrusy/ Sweet
- Caryophyllene or Humulene-dominant - Spicy/Woody
- Linalool-dominant - Floral/Lavender
- Pinene-dominant - Pine/Fresh
Because of their lower yield and the delicate, complex extraction process, these terpenes are much more expensive than Botanically Derived Terpene (BDT).
BDTs are extracted from non-cannabis plants, often from fruits and herbs such as lavender, citrus, and pine.
They recreate specific cannabis profiles by blending terpenes and yet offer unique, non-cannabis flavors. They are also less expensive because they’re widely available and legal in all states.
The quality and quantity of terpenes are important for a more enjoyable experience. Higher-quality, balanced levels will produce smoother vapor and smoke. On the other hand, synthetic, low-quality, or excessive terpene levels can create a harsh, irritating effect.
Both cannabinoids and terpenes work together rather than individually to enhance the overall therapeutic and psychoactive impact of the cannabis oil, known as the entourage effect.

Carrier Oils & Diluting or Thinning Agent
Some carts, particularly low-quality and older products, contain carrier oils or thinning agents to dilute pure and thick cannabis oil to make it smooth and vaporize properly.
Low-quality vape carts contain these, while high-quality ones contain only live resin or distillate and the terpene.
Some of the common carrier oils used are:
- MCT oil (derived from coconut oil)
- Propylene glycol or Vegetable glycerin
- Vitamin-E acetate
While many of these thinning agents are food-safe, they are not particularly “inhalation-safe.” The Vitamin-E acetate, for example, has been linked to the 2019 e-cigarette or vaping product use-associated lung injury (EVALI) outbreak.
When heated, some thinning agents can break down into harmful, carcinogenic compounds, such as formaldehyde, the primary chemical used to preserve dead bodies during the embalming process.
4 Most Popular Types of Cannabis Vape Cartridges
Cannabis oils aren't as straightforward as they seem. It's actually made with different extraction methods and processing techniques, which can affect consumer experience.
These extracts are concentrated products derived from the cannabis plant using methods such as CO2 or ethanol extraction, including oils, tinctures, waxes, and shatter.
Distillate Carts
Distillates are highly refined, potent oils produced by heat distillation to isolate the desired cannabinoids. It can comprise about 85% to 95% of THC or CBD, or a combination of both in specific ratios.
It is pure, usually clear or amber in color, odorless, and may contain artificial or cannabis-derived terpenes for flavor and aroma. It is often thin to medium in viscosity, and it flows easily when warm.
Distillates are the most common in the market, and the most budget-friendly, too. While it's consistent and potent, it can also lack the "entourage effect" of the natural plant.
Live Resin Carts
For the flavor chasers, live resin carts are the usual favorite.
Live resin tries to preserve a high amount of the natural terpenes of the cannabis by using hydrocarbon extraction. It uses fresh-frozen, uncured plant that results in an intense, strain-specific flavor.
It typically contains 60% to 85% of THC with all the natural terpenes of the plant preserved, which can mimic the flavor and aroma of the living cannabis plant.
Live resins are slightly thicker than distillates and have a medium viscosity. It is also golden to dark amber in color and has a very rich, "dank," and authentic strain flavor.
Liquid Diamond Carts
This cart is a hybrid concentrate that contains melted, highly-purified THC crystals or THCa diamonds, mixed often with high-terpene extract (HTE).
It typically has 80% to 90%+ cannabinoid content and about 10% to 20% terpene in the HTE sauce, offering the maximum potency among the popular types of cannabis carts, perfect for experienced users.
Because it is made of THC crystals, it tends to crystallize when not formulated properly. It is light gold in color and can sometimes get cloudy.
Live Rosin Cart
For the connoisseur who prioritizes flavor and full spectrum "high-end" experience, live Rosin carts are a popular option. It is a solventless extract created by applying heat and pressure to flash-frozen cannabis.
It has no chemicals used in extraction, which makes it the most "natural" or "purest" concentrate, and the most expensive, too.
Live rosins often read a 65% to 80% THC content, which is lower than distillates, but offer a full-spectrum experience.
The Hardware Components In Your Cannabis Vape Cartridge
The second major part of your cannabis vape cart is the hardware itself, the physical cartridge structure that holds the oil, heats and vaporizes it, and the mouthpiece where you draw vapor out to inhale.
Let’s break it down into individual elements below.
Cartridge Tank or Reservoir
The cartridge tank is what holds the oil in your vape. They’re usually made of high-quality borosilicate glass or polycarbonate, both of which are resistant to high heat.
Cart tanks are also typically transparent for easier oil inspection, but some are made of metal, making this impossible.

Atomizer (Heating Element)
This is the part that’s actually responsible for vapor production, as it heats the cannabis oil and converts it to vapor.
The atomizer often includes a wicking material, such as ceramic or cotton, which absorbs the liquid, and a heating coil, commonly made of mesh, metal, or ceramic, which heats the oil to boiling temperatures.
Some illegal manufacturers also produce counterfeit or substandard coils; be careful with these, as low-quality coils can cause your vape device to overheat, posing health hazards or even leading to a fire.
Overheated oil can also produce a burnt, sharp taste and smell, affecting the overall vaping experience.
Mouthpiece
The mouthpiece not only provides an airflow from the device to the mouth, but it also serves an aesthetic purpose and adds to the overall tactile experience of vaping a cannabis cart.
Also known as the drip tip, the mouthpiece is commonly made with plastic, metal, ceramic, and wood.
Whatever you choose will depend on your preferred comfort, appearance, durability, and brand perception.
The Base & Threading
This is the part that connects the vape cartridge to the battery.
The universal standard for vape pens is the 510 thread, which allows parts from different brands to be interchangeable. The 510 thread has a 7mm diameter and 10 threads at a 0.5mm pitch.
The connection includes a base plate for stability, the threads, and a center pin for electrical contact.
It’s important to keep this sealed to prevent leaks, which not only waste oil and make a mess but can also reduce vapor production.

Chimney
Inside your vape cart, you’ll also see a metal tube running through the center of the cartridge, which connects the heating coil to the mouthpiece.
This is the center post or the chimney, where the vapor travels as you inhale.
Frequently Asked Questions
Do cannabis carts contain nicotine?
No, cannabis cartridges typically contain THC or CBD oil, not nicotine. Nicotine is found in e-cigarette or tobacco vape products.
VapePensWholesale.com does not sell or endorse any nicotine-containing items. All products on this site are designed for cannabis use only.
Always check the label to confirm the contents, especially in unregulated markets.
How often should I change my vape cartridge?
Most prefilled cartridges are meant to be replaced once the oil runs out, which can vary depending on usage.
If you notice a burnt taste, clogging, or reduced vapor production, it’s usually time to replace it.
Refillable cartridges may need to be replaced after multiple uses as the coil wears out.
How to make a vape cartridge last longer?
Store it upright in a cool, dark place to preserve oil quality.
Take slow, moderate puffs rather than long, high-heat draws to prevent burning the oil.
Using lower voltage settings (if adjustable) can also help extend the cartridge’s lifespan.
