Delta-8 Carts

Your Guide to Delta-8 Carts

Delta 8 carts (also called Delta-8 THC vape cartridges) are pre-filled cartridges that deliver a smooth, clear-headed high using hemp derived Delta-8 THC. They're less intense than Delta-9 THC but still offer powerful effects perfect for relaxing without the couch-lock.

Unlike traditional cannabis carts, Delta 8 THC cartridges are federally legal under the 2018 Farm Bill, provided they contain less than 0.3% Delta-9 THC. That said, laws vary by state so always check your local regulations before ordering Delta 8 products.

Determining the Right Potency

The potency of your delta-8 carts will have the biggest impact on your experience. JustKana’s carts contain 900mg of delta-8 THC, which most consider somewhere between moderately to very potent.

If you’re new to delta-8, we recommend starting low and going slow. Take one or two puffs that last no longer than a few seconds, then wait between 5 and 15 minutes to gauge its effects. You can take more as-needed until you find that perfect dose for you!

Using and Maintaining Your Vape Cartridges

Our D8 carts are universally compatible with all 510-thread batteries. For best results, charge the battery fully before screwing on your delta-8 THC cartridge. Lower- or adjustable-voltage batteries are recommended for better flavor and to preserve both the terpene and cannabinoid profiles.

To avoid spills, leaks, or general degradation, store all cartridges upright and in dark, cool areas. Clean the contact points on both the battery and cartridge with rubbing alcohol and a cotton swab to ensure that residue does not hinder power flow.

Delta 8 Carts – Frequently Asked Questions

What is a Delta 8 cart?

A Delta 8 cart is a pre-filled vape cartridge containing Delta-8 THC oil, designed for use with a 510-thread battery. It delivers a smooth, mildly psychoactive experience with effects that are often described as relaxing, uplifting, and mentally clear — without the intensity of Delta-9 THC.

Will a Delta 8 cart get me high?

Yes, but not in the same way as Delta-9 THC. A Delta 8 cart offers a more mellow high that many users describe as clear-headed, calming, and anxiety-free. It’s ideal for those who want to feel elevated without feeling overwhelmed.

How long does a Delta 8 vape cart last?

Each Delta 8 vape cart typically provides 300–500 puffs depending on usage habits and battery settings. With moderate use, a 900mg cart can last anywhere from several days to a few weeks.

Are Delta 8 carts legal?

Delta 8 carts are federally legal under the 2018 Farm Bill as long as they’re derived from hemp and contain less than 0.3% Delta-9 THC. However, some U.S. states have restricted or banned Delta-8. Always check your local laws before purchasing.

What’s the difference between Delta 8 carts and Delta 8 disposables?

A Delta 8 cart requires a separate 510-thread vape battery, while disposables are all-in-one devices with a built-in battery and pre-charged functionality. Carts are great if you already own a battery, while disposables are more convenient for on-the-go use.

How do I use a Delta 8 THC cart?

Screw the cart onto a compatible 510-thread battery. Take 1–2 light puffs and wait 10–15 minutes to assess the effects. Start slow — especially if you’re new to Delta-8. Store the cart upright in a cool, dry place when not in useAre JustKana’s Delta 8 carts lab-tested?

Yes! Every Delta 8 THC cart from JustKana is tested by an independent third-party lab to verify potency, purity, and safety. You’ll never find MCT oil, PG, VG, or any synthetic additives in our products — just clean, hemp-derived Delta-8 and natural terpenes.
