'Marijuana' is considered a racist term in the industry. The preferred word is 'cannabis'.
so here's some history. the name "marijuana" was pushed by Harry Anslinger[0] as a way to trigger racial anxiety amongst conservative whites who held negative views with respect towards Mexicans. the other names for the plant being "hemp" (a non-psychoactive strain used as an industrial fiber crop) and "cannabis" (latin name for the genus of the plant).
