Mars Wrigley has taken legal action in both the United States and Canada to send the illicit cannabis market a signal to stop illegally using the company's brands and products. 

The lawsuit is intended to stop the illegal misuse of its trademarks in the marketing and sale of THC-infused edibles, which closely resemble Mars Wrigley's genuine products such as Skittles and Starburst. Mars Wrigley does not manufacture or sell any products containing THC.

Like other consumer packaged goods brands, Mars Wrigley brands are being used without authorization to create fake THC packaging, which is sold empty and then filled with THC-infused candies to market and sell THC products that look substantially like genuine candies.

Mars Wrigley strongly condemns the use of popular candy brands in the marketing and sale of THC products, which it considers deceptive and irresponsible. The use of Mars Wrigley's brands in this manner is unauthorized, inappropriate and must cease, especially to protect children from mistakenly ingesting these unlawful THC products.

Mars Wrigley has filed an additional lawsuit in the U.S. against a company selling a marijuana strain and related products under the name Zkittlez, bearing an extreme likeness to a Mars Wrigley brand.
