Delta 8 THC has become one of the fastest-growing trends in the cannabis industry. Known for offering a smoother and milder high than Delta 9 THC, it’s especially popular among people looking for relaxation without overwhelming effects. In 2025, the two most common ways people enjoy Delta 8 disposable vape pens and carts (cartridges). But which is the better option for you this year?
In this guide, we’ll break down the pros and cons of Delta 8 disposables and carts, their differences, costs, convenience, and what to expect in 2025.
What Are Delta 8 Disposable Vape Pens?
A Delta 8 disposable vape pen is a self-contained device pre-filled with Delta 8 oil. It comes with a built-in battery and is designed for single use. Once the oil is finished, the entire pen is discarded.
Key Features of Disposables
- Pre-filled and ready to use
- Built-in battery (usually rechargeable)
- Compact and discreet
- No maintenance required
Why People Like Them
- Convenience: No need to buy a separate battery.
- Portability: Perfect for travel and on-the-go use.
- Ease of use: Just open the package and start vaping.
- Variety: Available in multiple strains, flavors, and potencies.
What Are Delta 8 Carts?
Delta 8 carts (short for cartridges) are small containers filled with Delta 8 THC oil. They are designed to attach to a separate vape battery, usually with a 510-thread connection.
Key Features of Carts
- Require a separate battery
- Come in 1g or 2g sizes
- Refillable only if designed as such (most are pre-filled)
- Typically made with glass and metal for durability
Why People Like Them
- Cost-effective: Usually cheaper per gram compared to disposables.
- Customizable: You can switch between different carts using the same battery.
- Eco-friendly: Less waste since you keep the battery and only replace the cart.
- Performance: High-quality batteries can deliver smoother hits.
Disposables vs. Carts: Side-by-Side Comparison
1. Convenience
- Disposables: Win for simplicity. No setup, charging is often optional, and you can toss it when done.
- Carts: Require a battery, which adds an extra step. However, once you own a battery, switching carts is easy.
2. Cost
- Disposables: Tend to cost more overall since you buy a new battery every time.
- Carts: More budget-friendly long term. Once you buy a battery, carts are cheaper per gram.
3. Portability
- Disposables: Sleek, lightweight, and discreet. Great for carrying in your pocket or bag.
- Carts: Slightly bulkier since they attach to a separate battery, but still portable.
4. Sustainability
- Disposables: Create more waste since the battery and oil chamber are tossed together.
- Carts: More eco-friendly. You only replace the oil cartridge, keeping the battery.
5. Performance & Flavor
- Disposables: Quality varies depending on the brand. Some may clog or run out of battery before the oil is finished.
- Carts: With a reliable battery, carts tend to provide more consistent vapor quality and better control over temperature.
6. Variety
- Disposables: Available in many flavors and strains but limited to single-use.
- Carts: You can keep multiple carts and swap depending on your mood or need.
7. Battery Life
- Disposables: Usually come with a small rechargeable battery. Sometimes the battery dies before the oil runs out.
- Carts: Use a separate, often higher-quality battery. Can last months or years with care.
