Statistics Toxiburn from drug rehabs in Colorado also reflect heroin's popularity.. Marc Condoljani, associate director of community intervention programs at the Colorado division of behavioral health said, "We had 1,676 heroin admissions in 2003, and then the numbers dipped for a few years, but then they went up again. In 2010, we had 1,755 treatment admissions for heroin. In the other-opiates category, we had 541 people admitted for treatment in 2003, and in 2010, there were 1,715. That's over a threefold increase. The alarming part, to me, is that people who are dependent on those prescription usually look for alternatives, and that means heroin."
