Think of terpenes and cannabinoids as the soul of cannabis.
Ozone, with its aggressive bite, rips at their delicate essence, leaving behind a dull, muted shadow of the original experience. Is that the legacy you want to build?

The Chemical-based "Open Air" procedures?
More like a petri dish for re-contamination. Ozone's superficial cleaning leaves your cannabis vulnerable to airborne invaders, waiting to latch on and multiply in the post-decontamination window. This is playing roulette with your reputation and your customers' well-being.


Understanding the ½ Kill Step™ in Cannabis Decontamination

When it comes to safeguarding your cannabis from microbial threats, choosing the right decontamination method is crucial. While gas and chemical approaches might seem appealing for their swiftness and cost-effectiveness, a closer look reveals significant drawbacks that jeopardize the quality and integrity of your precious flower.

Surface Skimming - Not Deep Cleansing
One major limitation of gas and chemical decontamination is their inability to penetrate the intricate structure of the cannabis flower. Imagine them simply skimming the surface like a light wind, while hidden pockets within the tightly packed buds and trichomes remain untouched. This leaves stubborn pathogens lurking inside, ready to resurge and potentially wreak havoc down the line.

The Oxidation Gamble - A Costly Trade-Off
Many gas and chemical processes rely on oxidation to deactivate microbes. However, this aggressive approach often comes at a steep price. The delicate terpenes and cannabinoids that define the aroma, flavor, and potency of your cannabis are also susceptible to oxidation. In essence, you trade microbial reduction for a duller, muted experience, impacting your brand and potentially disappointing your customers.

Chemical Residue - A Lingering Shadow
Some chemical-based decontamination methods can leave behind residual traces on the flower. These residues, even if deemed safe individually, can interact with each other or with the natural compounds in cannabis, potentially leading to unforeseen health concerns and undesirable taste or aroma alterations.

Open-Air Exposure - A Recipe for Reinvasion
Even after undergoing gas or chemical decontamination, the potential risks aren't over. If the process allows for exposure to open air after treatment, airborne microbes can easily land and colonize the sterilized surface. This creates a vulnerable window for re-contamination before the cannabis reaches its final packaging, jeopardizing product safety and adding unnecessary complexity to your operations.



Technology Choices Matter, Choose Wisely™

Unlike other options that penetrate deeper (QUASTAR), ozone and hydrogen peroxide primarily tackles the surface of cannabis flowers. This leaves potential microbial havens nestled within the intricate bud structure, casting doubt on its ability to comprehensively address internal contamination.

Limited Reach, Questionable Defense
Unlike other decontamination methods capable of deeper penetration, ozone primarily acts on the surface of cannabis flowers. This leaves potential microbial havens within the intricate bud structure, raising questions about its overall effectiveness in addressing internal contamination.

Cannabinoid Degradation
Ozone's oxidizing nature presents a critical concern. Studies indicate it can degrade sensitive cannabinoids, particularly THC, the primary psychoactive compound. This process, known as ozonolysis, transforms THC into the less potent CBN, potentially diminishing the therapeutic or recreational value of the flower.

Terpene Transformation
Beyond cannabinoids, ozone's reactivity extends to terpenes, the aromatic compounds responsible for the distinct scents and flavors of cannabis strains. This interaction leads to terpene degradation, robbing the flower of its characteristic aromas and flavors, thereby jeopardizing the sensory experience of cannabis consumption.

Chemical Composition Alteration
The complex organic chemistry of cannabis flowers offers a multitude of targets for ozone's reactivity. Its interaction with various compounds can lead to the formation of unidentified byproducts with potentially unknown pharmacological or toxicological effects, introducing an element of uncertainty and potential risk into the decontamination process. champions evidence-based approaches to microbial control in cannabis.
