n Columbia you can score a KG of really pure coke for ~$1200 USD and in the US it's like $25,000 USD if you're lucky and it's probably cut to shit.
The only logical reason I can think of why it's so expensive outside of South America is because the methods the cartels use to transport it. Like having to build submarines and shit the costs add up.
Is this the only reason why?
Supply and Demand.
