Universal Symbol

The Marijuana Legalization Act requires the use of an 'universal symbol' indicating that a container, package or product contains marijuana or is a marijuana product.

To deploy Maine’s universal symbol, OMP chose to partner with the Massachusetts Cannabis Control Commission to unveil the first-ever shared universal symbol for marijuana and marijuana products. The symbol—which has already been successfully used in the Commonwealth of Massachusetts—features a red triangle above text reading “CONTAINS THC”. Centered within the triangle is a black marijuana leaf superimposed on a field of white. THC is the common acronym for tetrahydrocannabinol, the psychoactive compound found in marijuana.

In Maine, use of the universal symbol is required by adult use marijuana licensees. For product packaging and labeling, the symbol must appear on the front or most predominantly displayed area of the marketing layer. It may appear no smaller than half an inch by half an inch. For edible marijuana products, each single standardized serving of marijuana must be marked, stamped or otherwise imprinted with the universal symbol directly on at least one side of the product. It may not appear less than a quarter of an inch by a quarter of an inch. These details and more are included in a non-exhaustive guidance document made available to interested parties. 

While not required, OMP encourages caregivers and dispensaries currently operating within Maine’s Medical Use of Marijuana Program to consider utilizing Maine’s universal symbol. In addition, it is making an optional "Not Safe for Kids" icon available for use by interested program registrants and licensees.
