Glo Carts THC cartridges typically consist of a cartridge filled with a liquid cannabis concentrate, often referred to as "oil," which is made by extracting THC from cannabis plants using solvents or other methods. The oil is then mixed with various other ingredients, such as terpenes, which are responsible for the flavor and aroma of cannabis, to create a final product that can be vaporized and inhaled.

To use a Glo extract Carts THC cartridge, it is typically screwed onto a compatible vaporizer pen or vape pen battery, which provides the power needed to heat the cartridge and vaporize the oil. When the user inhales from the mouthpiece of the cartridge, the heated oil is vaporized and inhaled into the lungs, where the THC is absorbed into the bloodstream through the lungs' thin membranes. This allows for a relatively quick onset of effects compared to other methods of cannabis consumption, such as smoking or eating edibles.

It's important to note that THC cartridges, including Glo Carts THC cartridges, contain highly concentrated THC and can be potent. It's crucial to start with a low dose and wait for the effects to kick in before using more, especially for inexperienced users. Additionally, the use of THC cartridges, like any form of cannabis consumption, may have legal restrictions depending on the jurisdiction, so it's important to be aware of local laws and regulations regarding cannabis use.
