Ever wish you could see what smoke does to your lungs in real time?
We did too. So we brought in the big guns: a lung simulator.
We’re not here to just talk about why we believe vaporization beats combustion—we're here to show you. In a side-by-side demo, we ran a classic preroll joint against our Odin device using a real-deal inhalation simulator. The results? Kinda gross (on one side) and super satisfying (on the other).
In this blog, we’re breaking down how a lung simulator works, what it reveals, and why heat-not-burn tech—like the Odin—is changing the game for flower lovers who want a cleaner, smoother, smarter high.
So… What is a Lung Simulator?
In simple terms, a lung simulator is a device that mimics human inhalation. Think of it as a mechanical set of lungs designed to “breathe in” vapor or smoke at controlled rates and volumes—just like a human would.
These simulators help researchers, labs, and innovators like us measure what’s actually entering your lungs when you light up—or heat up—cannabis. They’re often used in the medical world to study inhalers, respiratory functions, or tobacco alternatives.
But we’re using it for something a little different: to show you what combustion leaves behind, and what vaporization leaves out.
How Does a Lung Simulator Work?
A lung simulator is a machine designed to mimic how humans breathe. It’s typically made with mechanical components that replicate inhalation and exhalation patterns, just like a person taking a puff off a joint or a vape.
Here’s how it goes down:
Programmable Breathing
At the core of the machine is a programmable pump system that recreates human-like inhalation. You can set it to “breathe” at precise intervals and volumes—for example, a 55 mL puff every 3 seconds—to reflect typical cannabis or nicotine use.
Because the lung simulator is so consistent, it’s the perfect tool for side-by-side comparisons. It removes user error or technique from the equation, creating a level playing field to observe how different products perform under identical conditions. We can control how long the inhale is and how much air is being taken in during each inhale. This level of control means we can keep all variables equal—so when we compare a joint to the Odin device, we know the difference in results isn’t about user technique. It’s about the tech.
Glass Tubes or Chambers
Connected to the simulator are clear glass tubes or chambers that serve two main functions:
-
They guide the inhaled substance—smoke or vapor—from the device to the simulated lungs.
-
They provide a visual record of what passes through.
Over time, these glass tubes reveal a lot. Smoke tends to leave behind visible residue—yellow stains, tar buildup, and particulate matter that clings to the surface. Vapor, on the other hand, is much cleaner. When vapor is drawn through the same glass tubes, they often remain clear, showing little to no residue.
This visible difference helps demonstrate, in real time, how much cleaner vaporization is compared to combustion.
Filters or Cotton Rounds
To take it a step further, a cotton filter is usually placed at the end of each airflow path, acting as a stand-in for your lungs' exhalation. As the machine “inhales” through the product and exhales through the cotton, you can see exactly what kind of byproducts are being deposited.
Heavily discolored cotton indicates more particulate matter and unwanted compounds. Cleaner cotton suggests a purer, less polluted inhalation experience.
Why It Matters
With a lung simulator, we can analyze not just what you’re breathing in—but what’s being left behind in your lungs over time. It’s a powerful tool for educating consumers, guiding product development, and reinforcing the health and efficiency benefits of cleaner consumption methods like vaporization.
The Experiment: Joint vs. Odin
What We Tested
-
On one side: a traditional preroll joint
-
On the other: the Odin device with our Nano Joint™—pre-filled with flower, designed to vaporize instead of burn.
Both were hooked up to the lung simulator, which inhaled at the exact same pace for each.
The Results
-
Glass tube from the joint → Yellow, sticky, and coated with smoke residue
-
Glass tube from the Odin → Clear, clean, and almost untouched
-
Cotton round from the joint → Brown, grimy, full of visible buildup
-
Cotton round from the Odin → Bright white with minimal residue
What you see in that demo is what your lungs would be dealing with in real life. And it’s not pretty—unless you’re on the vapor side.
Heat-Not-Burn vs. Combustion
Here’s the big difference: combustion destroys, while heat-not-burn preserves.
-
Combustion (like joints, pipes, bongs) involves temperatures upwards of 600°F, instantly incinerating your flower and releasing not just cannabinoids—but also tar, ash, and carcinogens.
-
Heat-not-burn devices gently warm the flower to a lower temperature (usually between 300°F–450°F), vaporizing the active compounds without setting the plant on fire.
This means you’re still getting everything you love—THC, CBD, terpenes—but none of the combustion-related junk your lungs didn’t ask for.
How does the Odin Work?
The Odin is our flagship heat-not-burn device built for people who want the ritual of flower without the smoke damage. It uses precise air based heating to gently vaporize our Nano Joints™—tiny, pre-filled flower sticks designed specifically for the Odin.
No torch. No ashtray. No hassle.
You insert the Nano Joint, press a button, and Odin heats your flower to the sweet spot—hot enough to activate the good stuff, but cool enough to avoid burning.
The result? Clean vapor, bold flavor, and a smoother experience that respects your lungs and your high.
Why It Matters
This test isn’t just about visuals, it’s about what those visuals represent:
-
Combustion = tar, ash, and unnecessary junk.
-
Vaporization = clean delivery of cannabinoids and terpenes without the burn.
The Odin gives you everything you want from flower—flavor, aroma, potency—without scorching it to hell. And thanks to the lung simulator, we’ve got proof that it’s not just hype—it’s science.
TL;DR
A lung simulator helps us replicate human inhalation in a controlled, visual way. And when we put our vapor up against traditional smoke, the difference is undeniable.
Because when you can see the truth, it's a whole lot easier to breathe easier.
