PGR Weed vs Natural Non-PGR Cannabis: A Comprehensive Comparison

Cannabis customers today make a different type of choice than ever before - they make a decision whether to buy a product created with synthetic, chemical compounds versus a product grown using organic methods. These choices have the ability to greatly impact both customer experience and their health.

As a person that has tried various products from well-established companies in legal marijuana states (i.e., CA, CO), I have come to realize that there are two very distinct options in terms of product creation.

What Are Plant Growth Regulators (PGRs)?

Plant Growth Regulators (PGRs) are synthetic chemical compounds that manipulate how plants develop in order to increase the amount of plant material produced (e.g., flowers, leaves). In cannabis cultivation, the primary purpose of PGRs is to increase the yield and density of buds (the area of the plant where the flowers grow). By increasing the density of buds, growers can sell their product as a heavier product which typically commands higher prices. However, although PGRs may increase yield and density of the buds produced by the plant, they do so at a cost to the natural chemistry of the plant.

I bought a beautiful example of a bud from a reputable company. It looked stunning - very heavy and "rock hard." When I broke it up, however, it had virtually no aroma - another sign that PGRs were likely used.

The Most Common Synthetic PGRs

There are several types of synthetic PGRs, but three common ones include:

Paclobutrazol - The most toxic of the three. Its combustion creates nitrosamines, a carcinogenic compound also found in cigarettes.
Daminozide (Alar) - The EPA has classified Alar as a probable carcinogen and banned its use on edible crops since 1999.
Chlormequat Chloride - Has been known to irritate skin and eyes, and excessive use can lead to damage to organs.

Many of these PGRs are forbidden from being used on edible crops, but are allowed for ornamental plants, which creates a loophole for some unscrupulous growers to take advantage of.

Spotting the Difference: A Physical Checklist

To identify PGR cannabis, you can check the physical characteristics. Several websites, including Leafly, note the following characteristics to help you identify PGR cannabis:

Characteristic	PGR Weed	Natural Cannabis
Bud Density & Texture	Dense, rock-hard, heavy; may feel spongy or wet .	Fluffy or naturally firm; breaks apart easily; sticky, resinous texture.
Aroma	Weak, grassy, or chemical-like smell due to suppressed terpene production .	Strong, complex, and aromatic scent from a rich terpene profile.
Visual Appearance	Excessive red/brown hairs (pistils); minimal crystal-like trichomes; dull, brownish-gray color .	Balanced pistil color; frosty with visible trichomes; vibrant greens, purples, or oranges.
Taste & Smoke	Harsh, chemical taste; produces a heavy, unpleasant smoke .	Smoother, flavorful smoke that reflects its aroma.
Effect	Often leads to a brief, lethargic, or "heavy-headed" high, followed by fatigue or a headache .	A cleaner, more distinct psychoactive or therapeutic effect aligned with the strain's profile.

The Data: Health Risks and Market Realities

While there is concern regarding the use of PGRs, it is not hypothetical. The regulated cannabis market is growing in part to eliminate the public health risks associated with PGRs. The US cannabis market is expected to reach $45 billion by the end of 2025. With 79% of Americans currently living in a county with a dispensary, access to tested products will continue to improve.

Medical consumers and those interested in wellness are a driving force behind this growth. The data indicates that nearly half of all consumers (48%) report using cannabis for pain relief and 45% for sleep. Consumers who fall within this category are particularly susceptible to the adverse effects of PGRs as the chemicals not only reduce the medicinal cannabinoids (THC/CBD) in the plant but also create additional toxins.

A recent LinkedIn post echoed my sentiments from numerous veteran consumers and budtenders. It stated that in some mature markets, it is "nearly impossible" to find natural flower. Unnaturally dense PGR buds are becoming the standard and are being misinterpreted as being high-quality by an uninformed public.

Quality Choice: An Informed Consumer Approach

During my experience, I have found that the best way to protect yourself from PGR cannabis is to be informed. Here are my suggestions:

Choose Quality Brands: Favoring the legal marketplace is the most effective way to minimize your exposure to PGR cannabis. Reputable brands operating in the legal marketplace such as RYTHM (top selling flower brand) or STIIIZY (top selling concentrate brand) will put their reputation on the line and will be forced to test their products for pesticides and other contaminants.
Trust Your Senses: Look at the flower before purchasing. Ask to see the product. If the flower lacks a scent and appears suspiciously perfect and dense, select a different option.
Ask Questions: Ask the budtender questions about the producer, cultivation techniques and whether the product has been lab-tested. A transparent approach is indicative of quality.
Recognize Established Brands: The marketplace is evolving and top-selling brands tend to be top-selling for a reason. Sales data indicate that established brands such as WYLD (edibles) and Dogwalkers (pre-rolls) have built significant credibility with consumers.

Ultimately, the decision to purchase PGR cannabis versus cannabis grown with organic methods is a decision based upon aesthetic vs. authenticity. The decision made by you has the potential to affect not only your short-term experience, but your long-term health. As the industry continues to expand, the demand by consumers for clean, organic and potent products is the greatest influence we have to direct the marketplace in the right direction.
