Cannabinoid Information and Testing Results on Cannabis Product Labels

As cannabis becomes more widely available through medical and recreational markets, consumers are met with an array of product labels filled with complex data. These labels contain vital information about the product’s potency, composition, and safety, yet they can be confusing to those unfamiliar with cannabis testing results. Understanding the details on cannabis labels can help consumers make informed decisions about their purchases, ensuring they select products that meet their needs and preferences.

Key Cannabinoids Listed on Labels

Cannabinoids are the active compounds in cannabis that interact with the body’s endocannabinoid system to produce various effects. The most commonly tested and labeled cannabinoids include:

THC (Tetrahydrocannabinol)
  • The primary psychoactive compound in cannabis.
  • Responsible for producing the “high” associated with cannabis use.
  • Labeled as Total THC or Δ9-THC.
  • Expressed in percentage or milligrams per gram (mg/g) of product.
CBD (Cannabidiol)
  • A non-psychoactive cannabinoid known for its potential therapeutic effects, including pain relief, anti-inflammatory properties, and anxiety reduction.
  • Often labeled as Total CBD.
  • Expressed in percentage or mg/g.
CBG (Cannabigerol)
  • Considered the “mother cannabinoid” because it is a precursor to THC and CBD.
  • Has potential antibacterial and neuroprotective properties.
CBN (Cannabinol)
  • Formed when THC degrades over time.
  • Known for its sedative effects, making it popular in sleep-focused cannabis products.
THCA (Tetrahydrocannabinolic Acid) & CBDA (Cannabidiolic Acid)
  • The acidic, non-psychoactive precursors to THC and CBD.
  • When heated (through smoking, vaping, or cooking), they convert into THC and CBD, respectively, in a process called decarboxylation.

Understanding Potency Testing Results

Cannabis labels often present cannabinoid content in two primary formats:

  • Percentage (%): Indicates the concentration of cannabinoids relative to the total weight of the product. For example, a cannabis flower labeled with 20% THC means that THC makes up 20% of the dry weight.
  • Milligrams per Gram (mg/g): Often used for concentrates, edibles, and tinctures. For example, a 10 mg THC gummy means that each gummy contains 10 mg of THC.

Terpenes and Their Role in Cannabis Effects

While cannabinoids are the main active compounds, terpenes also play a significant role in the overall cannabis experience. Terpenes are aromatic compounds found in cannabis that contribute to its scent and flavor, as well as influence the effects of cannabinoids. Some common terpenes found on labels include:

  • Myrcene: Known for its relaxing and sedative properties.
  • Limonene: Provides citrus aromas and is associated with uplifting effects.
  • Pinene: Found in pine trees and may promote alertness and memory retention.
  • Linalool: Has a floral aroma and is often linked to stress relief.

Contaminant Testing and Safety

Regulated cannabis products undergo testing to ensure they are free from harmful contaminants. Testing results for safety often include:

Pesticides
  • Residual pesticides can be harmful if consumed in high amounts.
  • Many states set strict limits on acceptable pesticide levels.
Heavy Metals
  • Cannabis plants absorb heavy metals from soil, including lead, mercury, and arsenic.
  • Labels should indicate whether a product has passed heavy metal testing.
Microbial Contaminants
  • Mold, bacteria, and yeast can be dangerous, particularly for individuals with compromised immune systems.
  • Testing ensures products are free from harmful microbial contamination.
Residual Solvents
  • Found in cannabis extracts, residual solvents such as butane or ethanol can remain if not properly purged.
  • Labels often indicate that the product meets safety limits for solvents.

Interpreting Expiration and Batch Numbers

Most cannabis labels include an expiration date or a “best by” date to indicate freshness and potency. The batch number helps track the product back to its original manufacturer and testing results. This is particularly useful in case of product recalls or quality concerns.

In Review

Understanding cannabis product labels is essential for making informed purchasing decisions. By examining potency levels, cannabinoid content, terpene profiles, and safety testing results, consumers can select products that align with their desired effects and medical needs. Whether choosing a high-THC flower, a CBD-rich tincture, or a terpene-forward vape cartridge, reading labels carefully ensures a safer and more satisfying cannabis experience.
