The phrase "how high" is best known as the title of a 2001 American stoner comedy film called "How High." The movie stars Method Man and Redman as two cannabis users who, after smoking a magical batch of marijuana fertilized with the ashes of a deceased friend, gain supernatural help to ace their college entrance exams and receive scholarships to Harvard University. The movie combines themes of college life, comedy, and stoner culture. It received generally negative reviews from critics but has a cult following and was noted for its humor and rap culture references. A sequel, "How High 2," was released in 2019.
