Strange question there, seeing as i'm posting from a biological perspective, purely scientifically in nature and not social which would comprise the "racist" concept that you speak of.Soooo...are you saying weed is racist?
From a biological perspective, the very same thing that protects black people from getting sun-induced skin cancer, is turned into poison through the chemical (burned) change of weed within the black mind.
Little note, Melanin and it's effect on the human black body has been classified above-top secret since 1945......
You wouldn't call black people dominating biologically such as the 100m in olympics or the 10.000m racist, but that's your pre-conditioned programming to protect white supremacy structure, including fighting against the myth that melanin makes black people superior even though we see it everywhere and in every sport and art.
Read this evidence by the world's foremost scientist into Melanin and it's effects and you'll understand. In your case, skip to part of the effects of drugs and alcohol on the black mind.
But musicians sing about getting high all the time right, so it must be cool...Who cares if it kills you...
