Exploring THC labelling preferences to communicate the strength of cannabis products: Insights from U.S. consumers.

As cannabis becomes legal in more places around the world, the products available to consumers have become more potent and varied—especially in terms of their THC (the main psychoactive ingredient) content. However, manufacturers don't always report THC levels consistently, which makes it difficult for consumers to understand how strong a product is or to use it safely. This research study investigated what type of THC labeling information consumers actually want to see on cannabis products to help them make informed choices.

The researchers explored different ways THC strength could be communicated on product labels, including standard units (like standardized servings), concentration percentages (how much THC is in the product), and total THC content (the absolute amount of THC in the entire package). By gathering preferences from U.S. consumers in legal cannabis markets, the team aimed to identify labeling approaches that would best help people understand product potency and understand the risks associated with different products.

This work has important practical implications: clear and consistent THC labeling could help consumers choose products appropriate for their experience level, reduce the risk of accidentally consuming too much THC, and support public health efforts in newly legal markets. The findings could inform policy decisions about how cannabis should be labeled and regulated, potentially setting standards that other regions might adopt as cannabis legalization continues to spread globally.
