Blackstone, medical use is just one aspect, Another is hemp fibres. Marijuana with very low THC levels can be grown on very marginal land to produce fibres for clothing rope or pulp for paper products.
At the moment we have tree farms on land that could support other agriculture which take years to grow before harvest to produce paper. Marijuana could be grown on lesser land and produce two crops a year, recall seeing some figures and works out cheaper and more productive than trees.
Alas, Marijuana even with very low THC levels are deemed illegal. I don't see the scene in that
