True. Luckily it's a much smaller market to begin with since most of the population drinks and only a relatively small fraction is interested in drugs besides marijuana.

I'm not really worried about the employment angle because cartel jobs aren't productive jobs. Essentially you're freeing up labor for the productive part of the economy which makes for a higher standard of living for everyone.

It might take a year or two to have nicely packaged heroin from well known companies available in pretty boxes in liquor stores, but I think you'd be rid of all the cartel violence within 6 months.
