THCH to THCA: How Today’s Top Vape Brands Like Torch and The Kind Pen Are Evolving

The cannabis vaporizer market is booming. It grew from about 5.05 billion in 2024 to 5.76 billion in 2025, and it’s expected to hit nearly 9.85 billion by 2029. THCH vape products have gained some attention lately, but THCA vape options are stepping into the spotlight. 

Brands like Torch and The Kind Pen are adjusting their offerings to follow that trend. In this guide, we clear up what’s shifting, how these brands are adapting, and what it means for your future vape choices.

Here’s what we’ll tackle:

• Definitions of THCH vape versus THCA vape, and what makes them different
• Why top brands are expanding beyond THCH
• How Torch vape and The Kind Pen are part of the shift
• What to look for when exploring THCA options

From THCH to THCA: The Cannabinoid Shift

Vape brands are steadily moving from THCH to THCA products, driven by changing regulations, raw material availability, and consumer curiosity about new cannabinoids with broader product potential.

THCH has been on the radar for a while, but it’s still considered a rare cannabinoid with limited large-scale production. That means fewer options on shelves, and often, those options stick to niche or limited runs. 

Brands noticed this gap. Instead of leaning only on THCH, they’re branching into THCA vape products that can be offered in a wider variety of formats.

THCA is picking up traction because it’s easier for brands to fit into different compliance categories. For example, a company that once had two THCH vape SKUs might now have four THCA SKUs and still keep a THCH option for loyal customers.

Why brands are diversifying cannabinoid offerings:

• Regulations in some states are clearer for THCA, giving brands a stable market to work with
• More supply sources for THCA allow consistent production schedules
• THCA products can be offered alongside other cannabinoids without overcomplicating production lines
• It gives customers more choice without abandoning older favorites

We’ve also seen some brands run seasonal batches of THCH products, testing new hardware or flavors, while keeping THCA as a year-round staple. This balance helps them meet demand without losing their more experimental side.

If you look at the wider hemp vape market, THCA now appears in more product catalogs than THCH. And for brands like Torch and The Kind Pen, this shift is as much about staying relevant as it is about keeping up with customer expectations.

Spotlight on Torch Vape

Torch built its name with hemp vapes that balance strong device engineering and dependable cannabinoid blends. That hasn’t changed. What’s new is how they’ve stepped into THCA without leaving behind their signature approach. Their THCA disposables come with hardware upgrades, higher capacities, and thoughtful blend profiles.

• The Diamond 2.0 in the Live Rosin THC-A 2.5G Disposable Vape Pen is a good example. It runs on the Firebug engine for consistent draws, Focus Flow for smooth delivery, and the Vision+ Display so you can track your usage and battery. It’s still button-operated with USB-C charging, but it feels like a refined version of earlier Torch designs.
• Then there’s the Pulse Live Resin THC-A 6G Disposable Vape Pen. This one is a box-style device with a postless dual airflow system and a preheat function for quick readiness. Six grams of capacity means fewer replacements, and the LED display makes it easy to keep an eye on levels.

Popular updates in the Torch THCA line include:

• Larger capacities for fewer swaps and longer use
• Hardware with visible usage tracking
• USB-C charging for quick turnaround
• Blend variety that covers multiple terpene profiles

It’s not just disposables, either. Torch continues to keep its catalog balanced with different cannabinoids, so long-time customers have options. This is part of why they’ve been able to adapt quickly. They’ve built trust through consistent quality control, with third-party lab tests available for every batch.

For anyone exploring THCA, Torch’s approach shows how a brand can shift focus without losing its identity. They keep the hardware and blend quality consistent, while letting the cannabinoid mix evolve with the market.

Spotlight on The Kind Pen

The Kind Pen isn’t new to building reliable vape gear. They’ve been making devices for over a decade, but their latest line shows they’re adapting for today’s market. Instead of sticking to a single product style, they’ve been introducing multi-format vaporizers and accessories that work with newer cannabinoids, including THCA.

• The Weezy Vaporizer stands out for its pop-up ceramic chamber, magnetic mouthpiece, and a 700mAh battery that holds up through long days. It’s compact, easy to clean, and the magnetic connection means you won’t deal with loose or messy fittings.
• If you want something slim for wax concentrates, the Slim Wax Vaporizer uses a ceramic heating chamber with titanium coils. It captures any excess product so you can reuse it, making it efficient without complicating the design.
• Then there’s The Don Vaporizer, a dual-use portable e-rig for wax and oils. It’s built with a quartz cup, adjustable temperature range, and even has built-in water filtration for smoother vapor.

Recent hardware highlights from The Kind Pen:

• Lifetime warranty across most devices
• Magnetic or leak-proof designs for less mess
• Multiple voltage or temperature settings for flexibility
• USB or USB-C charging for faster turnaround

These upgrades matter because they match the way people use vapes now: more variety in cannabinoids, more need for easy maintenance, and gear that lasts. The Kind Pen is refining devices so they keep working years after you buy them.

Industry Trends Driving Change

The hemp vape industry moves fast. Regulations in certain states now define THCA more clearly than other emerging cannabinoids, so brands have an easier time keeping those products on shelves without sudden pullbacks. That clarity affects what manufacturers choose to scale.

Supply also plays a role. THCA production has more established sourcing channels compared to THCH, so it’s less risky for a brand to plan larger runs. For companies already managing multiple cannabinoids, this reliability matters. You can’t build a seasonal release schedule if your raw material pipeline keeps stalling.

Customer behavior has shifted too. People aren’t buying one product and sticking with it for years. They try different cannabinoids, different devices, and even different capacity sizes.

Key factors behind the market shift:

• State-level rules that recognize THCA in more defined terms
• Consistent raw material sourcing for THCA products
• Customers actively seeking variety in both cannabinoids and devices
• Competition that rewards brands able to adapt quickly

We’ve also seen product categories expand. Disposables now come in larger capacities, cartridges have improved coil technology, and cross-compatibility between devices is more common.

All of these shifts feed into one reality: brands can’t just stand still. The market rewards those who adjust quickly, but without cutting corners on quality or consistency.

Choosing Your Brand and Cannabinoid

Picking between THCA and THCH products comes down to brand trust, lab transparency, and how well a device fits your daily routine.

Start with reputation. A brand that shares third-party lab results on every batch is showing you exactly what you’re paying for. That’s why we keep lab reports easy to find on our page. It’s proof of purity and accuracy in cannabinoid levels.

Then think about device format. If you’re someone who prefers longer use between recharges, something like a high-capacity disposable from Torch might be the right fit. If you value lifetime warranties and adaptable hardware, a unit from The Kind Pen could be the better match.

Things to consider when choosing:

• Lab testing: Is the report easy to read and recent?
• Device capacity: Larger grams mean fewer replacements.
• Charging style: USB or USB-C can make a difference if you need quick turnarounds.
• Warranty: Long coverage often signals brand confidence in build quality.
• Compatibility: Some batteries work with multiple cartridge types, giving you flexibility.

Trying different cannabinoids also makes sense. You may find THCA fits your routine better, or that you still like keeping a THCH option around. You don’t have to commit to one forever, it’s fine to keep both in rotation if your state laws allow it.

Final Thoughts

THCA and THCH both have a place in the market, but brands that adapt quickly and maintain consistent quality are the ones earning repeat customers.

The move from THCH to THCA is a response to better supply consistency, clearer compliance rules, and customers who want more than one option on the shelf. Brands like Torch and The Kind Pen have made that pivot without losing the build quality or transparency that got them here in the first place.
