There are the local arguments that I've seen about race, incarceration rates, and possession of marijuana.
But I look at this globally and with a North-South lens.
All this big companies in Canada are going to make piles of money on the production and sale of weed.
Meanwhile, you've got the Caribbean, with the perfect growing conditions (literally can grow weed like a weed), and no one is having conversations about the global trade in marijuana.
This could be a form of reparations.
Open up the trading routes for weed from former slave states in the Caribbean, tax the shit out of it. Meanwhile it creates jobs (and an entire economy) and pumps money back in the region.
This could be a mini sugar revolution.
