I think its a weird one. From my interpretation of videos ive seen of him he seriously advocated marijuana consumption, also disliked capitalism and its forces.
The most valuable assets bob marley left behind are in my opinion his pictures. And im very sure the family lawyers have spent a fuck lot of money buying his photos from journal;ists over time. His image is whats valuable.
In a way i think itd be glad a lot of people are consuming weed though i think itd make so that his organization would break even or use profits to help with the healing of the nation.
Overall i dont think weed was as big an aspect to bob marley as a whole as people already see him and might see even more. He clearly was all about the music.
