Today, the multicultural face of Toronto is well reflected in the city's underworld, which includes everything from Jamaican posses to Eastern European bratvas and to American biker gangs. The genesis of many foreign criminal organizations in Toronto has often been linked to the drug trade, as with the large influx of heroin and various Asian triads during the 1970s, or cocaine and South American cartels in the 1980s. These criminal groups, however, occasionally have a political bent as well, as with the Tamil organized crime groups such as the VVT and rival AK Kannan gangs, which warred with each other in the city's streets during the 1990s and early 2000s over the brown heroin trade. In recent decades, Toronto has also seen an infiltration of major American street gangs such as the Bloods, Crips, and Mara Salvatrucha.
