Infused edibles can take many forms, candies, chocolate, gummies; but how can you tell an edible from a regular candy?

THC-infused edibles are the fastest growing sector in the cannabis consumables market. Safe consumption has been a hot topic in many States, resulting in the creation of regulations to establish safeguards for the public. A few surefire ways have been put forward to ban any resemblance to mainstream candy, restrict shapes and designs to make them less appealing to children, and even restrict how products can be advertised.

The simple fact however remains, a bare product in your hand, with no packaging, no labeling, could be anything. Even adults may struggle to spot the difference between an edible and a regular candy. And so began the creation of the first cannabis warning symbol for products containing cannabis, specifically THC.

On October 1, 2016, Oregon released a symbol for use on cannabis products. This paved the way for the use of symbols to determine cannabis content. But this symbol was only required on the labeling of a product - was this enough?

Colorado went one step further that very same year - a direct imprint of the symbol itself onto the physical edible. The Colorado THC Symbol, or the ‘Universal Symbol’, quickly became the ‘recognized’ symbol.

Universal? Yes. Adopted elsewhere? Yes (Florida, Ohio, and a variant in New Mexico). The success of the Colorado Symbol led to the creation of a symbol in Massachusetts, which in turn became a stable symbol for a number of States in New England.

The Universal Symbol, however, almost seemed set to become the face of edibles in North America (hence the name). Did it? Not entirely. As of 2022, there are approximately 18 symbols across North America.

It is worth noting that not all States require symbols to be printed directly on to an edible, but packaging and labeling regulations have been introduced to ensure products (whether individual servings, or mass packaged) are marked appropriately.

Maryland THC Symbol

Michigan THC Symbol

Updated by the Cannabis Regulatory Agency, the State of Michigan adopted its own Symbol for use in all products as regulated under the Administrative Rules for the Medical Marihuana Facilities Licensing Act.

MO State Symbol

Missouri THC Symbol 

The Revised Statutes of Missouri brought an amended take to the Colorado Universal Symbol in 2020, requiring each package contain the symbol along with “the letter ‘M’ located under the ‘THC’ in the diamond, to signify that the product is for medical purposes”.

Montana THC Symbol

Montana THC Symbol

Beginning January 1 2022, the State of Montana adopted the IICPS Marijuana Symbol, with the wording ‘Marijuana’ added to the design. The general labeling requirements dictate a minimum size of 0.33 by 0.33 inches.

New Jersey THC Symbol

Also adopting the IICPS Marijuana Symbol, New Jersey’s Cannabis Regulatory Commission requires edibles be marked with the adopted symbol, in a size no smaller than 0.25 by 0.25 inches.

New York Symbol

New York THC Symbol

New York recently designed and introduced a THC Warning Symbol, however the State became a first in combining three symbols into one design (the THC element shown above); requiring the symbols be affixed to packaging of any edible and beverage cannabis product in the State.

Nevada THC Symbol

Nevada THC Symbol

January 1, 2019 saw the introduction of the Nevada State Symbol, requiring products that are ‘practical to stamp or mold’ be stamped accordingly. Nevada went one step further in stating any other way of demarking edibles be approved at a State Level.

Ohio THC Symbol

Ohio THC Symbol

The State of Ohio Board of Pharmacy indicated use of the Colorado Universal Symbol from May 2019, requiring each serving be marked with the Symbol - the main purpose being to ‘protect public health in reducing the risk of accidental ingestion’.

Rhode Island THC Symbol

Rhode Island THC Symbol

The Office of Cannabis Regulation introduced the Massachusetts Symbol in March 2020. May 2022 saw the legalization of recreational cannabis in the State.

Vermont THC Symbol

Vermont THC Symbol

The State of Vermont appears to use the same symbol as Massachusetts, Maine and Rhode Island, however there is a subtle difference. Where the overall design of the symbol is the same, the State appears to have adopted the IICPS leaf instead of the existing leaf on the Massachusetts symbol. The regulations dictate its usage as no less than 0.25 by 0.25 inches. Think you can use the Massachusetts symbol instead? That’s not the case - the State indicates the symbol cannot be modified in any manner.

Washington THC Symbol

Washington THC Symbol

The State of Washington updated labeling policies in 2019. The distinct symbol is used for all labeling of cannabis products, along with a secondary ‘Not for Kids’ logo.

The Future of THC Symbols

Authorities Logos


With just under half of the United States yet to achieve legal cannabis legislation (if at all), it is possible that further symbols will be designed/created/recreated at a State Level. It also remains to be seen if the IICPS symbol could become the primary symbol for cannabis use. One thing to be sure of is that symbols are not going away. The adoption of symbols has proven to be effective in safeguarding the public from accidental ingestion of cannabis products.
