If a drink is infused with cannabis but not alcohol, it technically falls under the category of a "mocktail" since the term "mocktail" is used to describe non-alcoholic beverages that resemble cocktails. However, given the psychoactive effects of cannabis (assuming the cannabis used contains THC), it's not just an ordinary mocktail. The term "cannabis-infused mocktail" or "THC-infused mocktail" would be more descriptive and accurate.
