This guy stashed 1,428 bags worth of heroin in his butt.

Vermont Police pulled over a man, Fernando Estrella, and a dog search showed the presence of narcotics.
 
No drugs were found, so a cavity search was ordered where they found three condoms full of Heroin, enough for 1,428 individual bags.
 
I dunno if there’s a record out there for most bags of heroin put up a butt, but if there is, this guy wins.
