What’s Inside A Cart? Weed and Cannabis Carts Explained

Many cannabis enjoyers have found that they like to use vape pens to consume due to their high potency, ease of use, and portability. These pens are made up of a cannabis cartridge, a battery, an atomizer, and a mouthpiece.

While all of these components are important, the cartridge, or cart, and its contents are undoubtedly the key players in determining the experience you have when you consume. In this article, we’ll be delving deeper into what exactly the cartridge is and what it contains. 

What’s a Cart?

These devices may be called Cannabis carts, vape pens, weed carts, or CBD weed carts, but they all utilize an atomizer to heat cannabis concentrate until it turns to vapor, which the user can then inhale.

The cart itself consists of cannabis concentrate or extracts that are inside a cart tank or container. The plant oil content varies in dosage, with 0.5 gram and 1 gram, or 500 mg and 1000 mg being available on the market today. The most common is the one-gram cart, followed by the half-gram cart. All-in-one vapes, also known as vape cartridges, are a popular option for cannabis consumers who want a discreet and convenient way to consume cannabis on the go. They offer a range of flavors and strains to choose from, and their small size and portability make them easy to use almost anywhere. Since they are pre-filled, there is no need to worry about the mess and inconvenience of filling the cartridge with cannabis extract.

In addition to different sizes, you will notice your weed cart carries a specific name related to a type of weed. These cart weed types are named after the specific strain of cannabis used to create the extract or concentrate contained within the cart. A cannabis strain is a biological term relating to the genetic makeup and breeding of the plant. Weed cart strains can encompass the lineage of a variety of aromatic components or possible effects. Different weed highs can be achieved by using different strains.

CBD Versus THC Cartridges 

The main difference between tetrahydrocannabinol (THC) and cannabidiol (CBD) is that THC has a psychoactive component, whereas CBD does not, meaning that THC is the compound that produces a “high” and CBD will not. CBD acts in conjunction with the body’s endocannabinoid system to fight stress and enhance relaxation. 

THC carts come in various strengths and flavors. Most THC oil carts range from 70-90% potency, while the highest THC content in a cartridge approaches 99%. When choosing a cannabis cart, consumers can select a product with primarily THC, CBD, or a combination of both. Products will commonly be labeled with the ratio of THC to CBD. This is a personal choice and should be based on the desired effect from a vape cart. 

A 1:1 ratio will contain equal amounts of THC and CBD, sometimes referred to as the “golden ratio.” A cart with this ratio may still have psychoactive effects, meaning it would produce a high, but the extent of those effects still depends on the THC content percentage. Therefore, the most potent cart will often be one of the highest THC carts, with a ratio that favors THC above other cannabinoids like CBD. 

Types of Weed Carts

To utilize a vape pen for cannabis consumption, pre-filled oil cartridges are the easiest way to go, as opposed to manually filling up cartridges with cart oil. 

Carts themselves can be 510-thread, device-specific pod, or all-in-one. The most common type of weed cart is a 510 thread. This means that this cartridge will attach to any common battery-powered pen with the same 510 threading. Device-specific pods that only attach to a specific brand of a vape pen can also be purchased. All-in-one pens are another way to consume cannabis through vaping. However, when these run out, they cannot be refilled, and you will need to purchase a new one. 

Live resin is created by flash-freezing live cannabis flower, which captures the rich natural terpenes, flavonoids, and other desirable characteristics of the specific strain used, resulting in a more aromatic, flavorful cart.  Full spectrum extracts are a subset of live resin oils that contain many cannabinoids such as THC, CBD, and CBN. They are more difficult to produce but result in an extract that is true to the original strain’s naturally-occurring chemical profile, which some cannabis connoisseurs will argue creates a more powerful elevating effect. 

You will find that regardless of the type of cartridge used, each specific concentrate has its own unique flavor. These can range from natural weed flavors to exotic tastes. Your weed cart’s flavors come from aromatic compounds called terpenes, which are found naturally in many plants. Kurvana products come in a variety of strains, such as Mimosa, Blackberry Kush, and Banana Smoothie. 

What’s Inside Fake Cartridges? 

Buying cartridges from an unauthorized dealer is never recommended, as there is no way to know what they contain. The risks include consuming products with low THC, poor quality standards, harmful additives, or untested ingredients, which can cause dangerous side effects. 

Any legitimate brand, including all Kurvana carts, will have testing information available online. It is always best to purchase from a licensed cart brand. 


Knowing what’s inside a cart is important to help you select the best weed cart for the experience you want to achieve, and to keep yourself safe from the dangers of fake carts. 


How many ml in a 1g cartridge?

A 1g cartridge contains approximately 1ml of cannabis oil. A gram (g) or milligram (mg) is a unit of measurement for weight, whereas a milliliter (ml) measures volume. In the case of vape cartridges, 1ml of concentrate weighs roughly 1g.

How many hits are in a cart? 

This depends on a variety of factors, including battery wattage, the viscosity of the oil, heat settings, and strength of the inhale. A 0.5g cartridge will provide the user with approximately 75-150 hits, for example. If you’re wondering how many puffs in a 1 ml cartridge, this will provide 150-300 puffs.

How long does a weed cartridge last?

When it comes to expiration dates, Kurvana weed cartridges last for at least 12 months from the date of purchase. But if you are wondering how long does a 0.5 g cartridge last, it depends on how often you use it. Three puffs a day of a 0.5 g cartridge would last around six weeks, while three puffs per day of a one-gram cart would last approximately three months. 

How many cart hits from a 0.5g cartridge to get high? 

The question of how many cart hits does it take to get high doesn’t depend on the size of the cart, but varies immensely based on the user’s tolerance, the strength of the inhale, THC content, the strain of weed, etc. Generally speaking, start with one hit and wait for the effects to kick in before taking another, and so on. The effects of a THC cart can usually be felt within a few seconds to a few minutes after consumption.
