The European Monitoring Centre for Drugs and Drug Addiction reports that the retail price of brown heroin varies from €14.5 per gram in Turkey to €110 per gram in Sweden, with most European countries reporting typical prices of €35-40 per gram. The price of white heroin is reported only by a few European countries and ranged between €27 and €110 per gram.
The United Nations Office on Drugs and Crime claims in its 2008 World Drug Report that typical US retail prices are US$172 per gram."
so 40,000 grams * (average) $100= $4,000,000
$4mn of heroin makes him a drug lord to me, esp cuz doubtful they found the whole amount he possessed
