You are correct:
John P. Walters, director of the Office of National Drug Control Policy, said marijuana, not heroin or cocaine, is the "bread and butter," "the center of gravity" for Mexican drug cartels that every year smuggle tons of it through the porous U.S.-Mexico border. Of the $13.8 billion that Americans contributed to Mexican drug traffickers in 2004-05, about 62 percent, or $8.6 billion, comes from marijuana consumption.

Gee, so let’s just legalize pot and that will eliminate the problem? LOL, don’t think so. Today’s pot is not the pot of the hippie generation, and once that’s OK, the crooks will be busy getting you hooked on the heroine they produce. Crime is a never-ending business that requires more vigilance than ever, not capitulation.
Question: Do you think the drug cartels would cease conducting illegal business if marijuana were legalized?
