This chemically modified cousin of CBD is made by transforming cannabinoids into their more potent acetate ester form. But as with many things in life, there’s a catch. The increased potency comes with significant risks, both in production and consumption.

When Heat Turns Deadly: The Ketene Conundrum

One might wonder, what’s the primary concern? It all boils down to heat. When THC-O is exposed to high temperatures, it undergoes thermal degradation and forms a dangerous lung toxicant called ketene. 

This alarming process echoes the 2019 vaping lung injury outbreak (erroneously dubbed “EVALI” by the CDC), where vitamin E acetate produced ketene when heated. In essence, the peril lies not within cannabis or vaping themselves but in the heat-driven interactions between acetates and various chemicals, including THC.

Safety First: Navigating the World of THC-O

It’s crucial to recognize that heat is our enemy here. Any acetate ester subjected to high temperatures could potentially create ketene. While it’s unclear if the amount generated by a vape cart poses an immediate threat, repeated small exposures may accumulate into significant lung damage over time.

On a brighter note, not all forms of THC-O are created equal. Gummies and tinctures offer a safer alternative for consumers since they don’t require heating and thus bypass the ketene danger zone.

However, producing THC-O remains a risky business due to its reliance on acetic anhydride – a volatile substance prone to causing fires and explosions. Crafting THC-O should be left to well-equipped labs and experts familiar with its intricate process. Even then, the final product may still harbor traces of harmful chemicals used in production.

A United Effort: Protecting the Cannabis Community

As THC-O gains momentum, it’s imperative for hemp growers, processors, and consumers to champion quality and safety. This means entrusting THC-O production to experienced professionals in well-equipped labs and subjecting the end product to rigorous testing to minimize potential hazards. By raising awareness about these issues, we can safeguard the well-being of cannabis users and foster responsible practices within this burgeoning industry.
