Who's using all the drugs?

I saw today on the news where some semi submersible boat carrying around 5 TONS of cocaine was seized. Now that's a lot of dope! We hear all the time that drug trafficking prevention costs us X number of dollars each year. My question is, why are there so many ignorant, stupid, insane people that use this crap anyway? Are we a country of losers that just don't give a darn any more?
