By killing or capturing at least seven top drug cartel leaders in the past year, the Mexican government is sending a message: "Kingpins, beware." But without confronting deeper problems of corruption, money laundering, weak police and courts, and overcrowded prisons, taking down capos will have little effect on the lucrative drug trade, instead risking more of the violence that is scaring off some investors, security experts say.

Of course you could just legalize it, and tax that "lucrative" market, while removing the "kingpins" source of income...
Prohibition of alcohol created the mafia in America... prohibbition of soft drugs creates the "cartels"....
legalize pot, and other soft drugs, and focus on the drugs that make addicts, thieves, and murderers out of once normal people...
