Vaping has become one of the most popular methods of consuming cannabidiol (CBD) for a variety of reasons. Vaping CBD is discrete and effective in treating everything—from anxiety and stress—to inflammation and migraines. One of the primary advantages of CBD vape cartridges is how quickly it takes effect and the high rate of absorption. But, whether you’re new to vaping CBD or you’re experienced, it can be hard to know how to choose the best CBD cartridges for sale. The following are some of the most essential facts to keep in mind while you shop for the best CBD pre-filled cartridges, through our large selection at

First Things First — What Are CBD Vape Cartridges?

Most vape pens come with a cartridge—a small tank (0.5 or 1 mL)—that holds CBD vape juice. There are two primary types of vape pen cartridges: pre-filled and refillable. The best CBD prefilled cartridge comes with CBD juice and when it is empty, you can simply throw it out or recycle it accordingly. On the other hand, refillable cartridges come empty, but you can buy vape juice separately to fill it up. We recommend buying refillable cartridges and CBD juice since it’s a more financially and environmentally friendly way to save.

How to Use CBD Vape Cartridges: Safety Tips

Now that you know how to choose the best CBD cartridges for sale, the next step is learning how to use them. If you’re simply refilling an empty cartridge, just unscrew the lid and fill it up with CBD vape juice. After about 15 minutes (allowing time for the juice to be absorbed in the vape coil), attach the cartridge to the device. On the other hand, if you’re using a pre-filled CBD vape pen cartridge, just attach it to your vape pen following the instructions that came with the product. As always, we recommend storing your CBD vape cartridges and pens in a cool, dry place to protect the integrity of the products.

How to Choose the Best CBD Cartridges for Sale

There are a few important criteria to look for when you’re figuring out how to choose the best CBD cartridges for sale. Primarily, you should look for a cartridge that is suited for you regarding potency and desired benefits. As always, you should ensure that the ingredients listed on the package are clear and accessible. Lastly, when you shop at, you can rest assured that all of our products come with Certificates of Analysis (CoA). Reviewing the CoA will inform you about the ingredients used, the manufacturing process, and the amount of THC in the product.

1. Type of Extract

Just like with any other CBD product, check to see what kind of CBD extract is used in the cartridge. Usually, your options will be full-spectrum hemp extract—which contains CBD and other cannabinoids or CBD isolate—which contains only CBD. If you’re looking for a holistic health outcome, you might try full-spectrum extracts that offer the “entourage effect,” where different cannabinoids work together for maximum impact. However, most CBD cartridges are isolate-based because they are typically easier and cheaper to manufacture.

2. Ingredients

The CBD industry is still not regulated by the FDA which means there are a lot of suspicious and even dangerous products on the market. When you’re seeking to choose the best CBD cartridges for sale, it is always a good idea to beware of extremely cheap products with ingredients you can’t pronounce. In fact, we suggest looking for cartridges or vape juice that is free of synthetic additives. While this may mean that the only thing used to flavor each cartridge is CBD and terpenes, it is typically a healthier route to take. Leafz also offers a guide to the best certified CBD oil for sale from the most reputable CBD companies, so that you don’t have to worry about the safety of your CBD products.

3. Third-Party Lab Testing

To ensure that CBD products are safe and legal, they should be third-party lab tested with a Certificate of Analysis. You can shop confidently at, knowing that all of our products come with Certificates of Analysis that prove that the product contains less than 0.3% THC—making it legal throughout the country. Additionally, this third-party lab testing ensures that the product doesn’t contain heavy metals, pesticides, or other dangerous ingredients. Of course, you can also check to see where the hemp was sourced to make your CBD product.

When you are ready to buy, you can depend on Leafz for the best online selection of CBD products, brands, and resources.
