Not a world capital of the stuff exactly but, due to slow-rolled legalization, New York City is having a gray market boom right now - there's some sort of tacit 'they can't catch all of us at once' strategy going on, there's a bazillion illegal (yet formalized) cannabis vendors springing up all over the place into every available empty storefront. You can also find them at farmer's markets, concerts, outside movie theaters, etc. Most of the gray market is just surplus California pot (it is the cheapest, after all) but if you go to one of the very few legal dispensaries in the city you can buy New York (State) grown cannabis which is pretty neat.
