Solventless cartridges (if referring to the ones created using a purely mechanical process) are generally more expensive than traditional cartridges that use solvents in the extraction process. This is because a solventless cart is made using a more time-consuming and labor-intensive process that involves pressing and extracting the oils from the cannabis plant without the use of solvents or chemicals. Additionally, these cartridges typically use higher-quality starting materials and are subject to more rigorous testing to ensure purity and quality. These factors contribute to the higher cost of these carts.
