Standardizing Cannabis Labeling for Health and Safety

As the US Federal government and individual states progress toward full cannabis legalization for both medical and adult use, establishing universal cannabis labeling standards is imperative. Presently, legalized states employ a disparate array of labeling systems, often falling short in serving the needs of public health, safety, patients, and consumers. This article advocates for the implementation of cannabis labeling standards that can serve as a foundational framework for the regulation of cannabis product packaging, spanning both medical and adult-use products.

The proposal includes two pivotal components: the Universal Cannabis Product Symbol (UCPS) and the Universal Cannabis Information Label (UCIL), designed to be applicable across a wide range of product types. The UCIL provides standardized product information, details about cannabinoids, terpenes, flavonoids, product warnings, lot numbers, expiration dates, and a QR code for additional information. When applicable, it also includes product ingredients and serving/dose quantification.

The Necessity of Cannabis Labeling Standards

As the United States makes significant strides toward full cannabis legalization, it is crucial to establish comprehensive cannabis product labeling regulations to safeguard public health and safety.

Current labeling standards vary widely among states that have legalized cannabis, leading to inconsistency and confusion. Many labels are inadequately designed, with small font sizes and ambiguous information, failing to meet the needs of consumers and patients alike.

Balancing Regulation

Cannabis regulations, especially labeling standards, must strike a delicate balance. Overly lax regulations can jeopardize public health and safety, while overly stringent ones can hinder the legal market’s competitiveness against illicit sources. Excessive labeling information can also obscure essential details in a sea of data and warnings.

The Proposed Solution

This article proposes two fundamental elements for a unified cannabis labeling standard, applicable to both medical and adult-use products:

  1. Universal Cannabis Product Symbol (UCPS): This symbol, displaying “Caution Before Cannabis,” should be prominently featured on all cannabis product packages, excluding those defined as hemp under federal law. The symbol comprises a bold exclamation point superimposed on a cannabis leaf, enclosed within a rounded triangular caution sign of a contrasting color


2.Universal Cannabis Information Label (UCIL): The UCIL offers crucial and user-friendly information about the product. It is divided into five color-coded sections, including Cannabis Information, Cannabinoid Profile, Ingredients, Warnings, and Lot Number/Expiration Date. The label is adaptable for various product forms, ensuring consistent information presentation.

The UCPS Advantages

  • The design is easily recognizable and conveys a cautionary message without implying prohibition or exaggerated dangers.
  • It incorporates a realistic silhouette of a cannabis leaf to aid identification and public education.
  • The exclamation point overlaid on the leaf emphasizes the importance of caution before using cannabis.

Universal Cannabis Information Label (UCIL)

The UCIL includes essential information relevant to the product, ensuring transparency and safety for consumers. It covers:

  1. Cannabis Information: This section provides details about the product form, weight, serving size (if applicable), total servings, and a QR code for additional information.
  2. Cannabinoid Profile: It outlines information about cannabinoids, terpenes, and flavonoids, with a focus on THC and CBD content. Nutritional information is included for edibles.
  3. Ingredients: This section lists all ingredients for edibles and inactive ingredients for other product forms.
  4. Warnings: A comprehensive warning section targets key at-risk groups, including all users, children, minors, individuals with psychiatric disorders, pregnant/breastfeeding women, and those operating machinery. Specific warnings for different product forms are provided.
  5. Lot Number and Expiration Date: These essential details help track product quality and safety.

Adapting the UCIL for Medical and Adult-Use Cannabis

The UCIL is designed to accommodate both medical and adult-use cannabis products, using terminology like “serving” and “consumer” for adult use and “dose” and “patient” for medical use. A clear “FOR MEDICAL USE ONLY” label distinguishes medical products.

Individually Boxed Sections of the UCIL

For some product forms, individual sections of the UCIL may be customized to each lot, while others allow for identical labels across many lots. The flexibility of the UCIL design accommodates these variations.

Style Guide

The template is designed for ease of use, employing different typefaces and weights to enhance readability and comprehension. The typeface, font size, and layout ensure information is organized and clear for laypeople.

Layout Options

The UCIL’s sections can be rearranged to suit different package sizes and shapes, with some exceptions, such as the brown “Ingredients” box, which must not be placed at the top of stacked UCIL sections.

Sample UCILs for Different Product Forms

Specific UCIL templates are provided for various product forms, including flower, inhaled extracts, oral extracts, edibles, topicals, suppositories, and transdermal patches, catering to the unique requirements of each product category.


The Universal Cannabis Product Symbol (UCPS) and Universal Cannabis Information Label (UCIL) set a new standard for cannabis labeling in the evolving regulated cannabis industry. These elements prioritize the interests of patients, consumers, public health, and public safety.

When federal law permits interstate cannabis commerce, the UCPS will play a vital role in facilitating product identification across state boundaries. The UCIL ensures consistency in presenting product information.

In addition to the UCPS and UCIL, other aspects of cannabis packaging, such as additional product information and design, should be considered to enhance safety, transparency, and market competitiveness.

Key questions, such as color scheme selection and serving size estimation for inhaled extracts, deserve further research and discussion. Cannabis stakeholders are encouraged to collaborate and adapt these proposed standards to their specific needs, promoting a safer and more consistent cannabis market.
