Customers buying from black markets have less choice.

If I want drugs, I buy the drugs the dealer is pushing.

In a legal market for sex, a customer can be more selective, so the less desired workers will lose customers.

When weed was legalized the bottom rung of the weed dealers, lost their market to stores who suddenly offered a better option to consumers.

Marginalization in the cannabis dealer scene would be poor people who sell a bit of weed to make ends meet or cheap/free weed in exchange for dealing.

I think you are over estimating a cross over between these customers. Cheap Mexican brick weed is still being sold because legal cannabis is pricing poorer users out of the legal market.

Legal stores are employing people legitimately and paying taxes, so I don't mind if some dealers now have to quit or diversify. The more jobs we have in legal drugs the fewer required in the illegal drug trade. This is a net positive to society.
