The dangers of PGR "CALI" in cannabis cultivation
Table of Contents
Introduction
Plant growth regulators (PGR) are chemical substances used in agriculture to improve crop yields. However, their use in cannabis cultivation raises many concerns. Contrary to popular belief, the term "CALI" does not refer to a specific variety of cannabis, but rather varieties grown in California. However, with the rise of the cannabis market, some varieties from Canada or Nevada are also called "CALI", even though many of them are grown with PGR. This phenomenon raises questions about the authenticity and quality of the products offered to consumers.
What is the PGR and why is it used?
The PGR (Plant Growth Regulators) are used to accelerate plant growth and increase their yield. They allow growers to produce denser, more compact, and visually appealing cannabis buds. However, these regulators alter the natural structure of the plant, thereby impacting the flavor, smell, and overall quality of the product. Unlike organic cultivation, where plants grow naturally, cannabis treated with PGR has an abnormally hard texture, often darker color, and a generally less resinous appearance.
Farmers use PGR mainly for economic reasons. Instead of using traditional nutrient and stimulants, some producers turn to plant growth regulators (PGR) to accelerate crop development and increase bud mass. These substances help optimize the profitability of harvests by increasing yields and improving the visual appearance of plants. However, this economic advantage comes with major health risks for consumers, as the accumulation of these compounds in crops can have harmful effects on long-term health.

The health risks associated with PGR
One of the main dangers of the PGR lies in its toxicity. Several studies have shown that some substances used in PGR are carcinogenic and can cause serious health problems. Inhaling cannabis treated with these chemicals exposes consumers to increased risks of respiratory disorders, lung irritations, and hormonal disruptions. Some PGR, such as paclobutrazol, daminozide, and chlormequat, are banned in several countries due to their harmful impact on health.
Regular consumption of cannabis containing PGR can also alter the nervous system and cause undesirable side effects such as headaches, nausea, and an unusual feeling of heaviness. Unlike organic cannabis, which offers a smoother and more authentic experience, chemically processed cannabis can provide a harsher and more irritating smoke sensation.
How to identify cannabis grown at PGR?
To avoid buying cannabis treated with PGR, it is essential to learn to recognize the distinctive signs. First of all, the appearance of the product is a key indicator. PGR buds are often abnormally dense, compact, and hard to the touch, which contrasts with natural buds that are more airy and resinous.
The smell is also a good indicator. If the cannabis has an artificial or muted smell, there is a strong chance it has been treated with PGR. Additionally, abnormal combustion, with thicker smoke and a metallic or chemical taste, may indicate the presence of these harmful substances.
The legislation surrounding PGR and their ban in California
Faced with the dangers of PGR, several states and countries have taken strict measures to ban their use in cannabis cultivation. California, one of the largest cannabis production centers in the world, has banned these chemicals due to their negative impact on public health. This ban sends a strong signal: if even California, where the cannabis industry is thriving, considers these substances dangerous, it is clear that their consumption poses a real danger.
"Other countries like Canada and several U.S. states have also strengthened their regulations to ensure the quality of legally sold cannabis. In Europe, awareness around this issue is increasing, although the black market remains a major vector for the distribution of cannabis treated with PGR."
Conclusion
The use of PGR in cannabis cultivation poses a major health issue for consumers. While these substances provide increased yields for producers, they harm the quality of the product and present significant health risks. Consumer vigilance, strict regulation, and the promotion of organic cultivation are key elements to ensure purer and safer cannabis. By prioritizing natural and certified products, everyone can contribute to a healthier and more responsible cannabis industry.
