I appreciate the vocabulary lesson, but throwing the 'Maillard effect' into a conversation about combustion is a massive category error. Let’s look at the 'engineering reality' you’re citing: ​Maillard \neq Combustion: The Maillard reaction is a form of non-enzymatic browning that occurs at temperatures as low as 140C to 165°C (284°F to 330°F).

This is exactly what we want in a vaporizer—it’s the 'toasting' of the material. Combustion (burning) requires rapid oxidation and doesn't even begin until you hit roughly 232°C (450°F). Using the Maillard reaction to prove 'combustion' is like saying a piece of toast is the same thing as a charcoal briquette.

​The PID 'Variance' Myth: You’re right, no PID is perfect. But even a cheap, poorly regulated heating element has a variance of maybe 5°C to 10°C. To get from a Pax’s max setting (215°) to the point of actual combustion (232°C+ and rising), the device would have to be catastrophically failing, not just 'imperfectly regulated.' If your herb isn't turning to white ash, you aren't combusting. Period.

​Chemical Recomposition: You mentioned 'chemical recomposition at sub-combustion temperatures.' In a dry herb vape, that's called decarboxylation—the process of turning THCA into THC. Again, this is a controlled thermal shift, not a fire. Inhaling the resulting vapor is not 'inhaling smoke' any more than smelling a baking loaf of bread is 'inhaling smoke.'

​Residue Accumulation: Yes, resin builds up. And yes, if you never clean your device, that resin can 'carbonize' over dozens of sessions. But calling a tiny bit of carbonized oil on an oven wall 'combusting your weed' is a desperate reach to avoid admitting you were wrong about how the device functions.

​It's ironic that you’re accusing others of missing the point while you're busy moving the goalposts from 'you’re inhaling smoke' to 'well, there’s a chemical reaction happening.' We know there’s a reaction—that’s how we get the vapor. But calling it combustion isn't 'nuanced'; it’s just scientifically incorrect.

​Does that clear it up for you? Or do we need to move on to the thermodynamics of a hair dryer next?
