hemp isn't marijuana (referring to psychoactive cannabis strains), by design.
(and less importantly (imo), marijuana is a slang term born from racist origins.[0][1])
I think that you mean 'cannabis related'.
Sorry if there is a perceived pedantry on my part; I just think that the distinction is important both conceptually and legislatively, especially given that other countries have understood the distinction between hemp and other cannabis products for some time.
