A new report from Bloomberg states that more Chicagoans are currently using heroin than there were in the 1970s, when heroin usage was at its previous "peak." Usage is up 79 percent in the last five years.

The report blames the the Sinaloa cartel, a Mexican drug organization, for the resurgence of heroin in the area that has spread to the Chicago surburbs and surrounding states like Wisconsin and Indiana. DuPage country has seen 43 fatal overdoses this year alone and Will Country recorded 53 in 2012. 

The cartel's hold on narcotics sales in the city has allowed them to increase the purity of street level heroin and decrease the price, making it cheaper and more powerful than pills. Local police believe this is why the drug has seen a spike amongst suburban teenagers.
