The trademark infringement lawsuit was filed in U.S. District Court in Denver this week against TinctureBelle LLC and TinctureBelle Marijuanka LLC.
It alleges TinctureBelle's Ganja Joy, Hasheath, Hashees and Dabby Patty mimic Hershey's Almond Joy, Heath, Reese's peanut butter cups and York peppermint patty candies, respectively.
TinctureBelle did not immediately return messages seeking comment. The Denver Business Journal first reported about the lawsuit filed Tuesday.
The company's website says its products, which include lotions and balms, are "diabetic safe and delicious" and helpful with a variety of issues, including pain, headaches and insomnia.
The edibles are sold in Colorado's legal pot shops and medical marijuana dispensaries.
Pennsylvania-based Hershey says TinctureBelle products are packaged in a way that will confuse consumers, including children. Hershey's suit says TinctureBelle "creates a genuine safety risk with regard to consumers" who may inadvertently eat them thinking they are ordinary chocolate candy.
