TIJUANA, MEXICO: MARCH 11, 2009: Man shooting Heroin in another man's neck near the U.S. border in Tijuana, Mexico on March 11, 2009. The border canal has become a regular spot for junkies to use Heroin, while the Mexican police do nothing the U.S border patrol are just out of jurisdiction. Tijuana is one of the major battlegrounds of the cartels in the ongoing Mexico Drug War, which has taken the lives of over 7,000 people since the beginning of 2007. The Obama administration is challenged to address Mexico's escalating war with drug cartels near the shared border.
