disposal of used needles and syringes". NEP were first established in the US in the late 1980s as a response to the HIV pandemic. Because federal funding has long been banned from being used for NEP, their prominence in the US has been minimal. However, in early 2016, in the face of the ever-increasing heroin crisis, Congress effectively rolled back those regulations and is now allowing federal funding to support certain aspects of NEP. NEP are cited by the CDC as a vital aspect of the multi-faceted approach to the opioid crisis. While opposition to NEP includes fears of increased drug use, studies have shown that they do not increase drug use among users or within a community. NEP have also been known to increase admittance into addiction treatment centers, offer counseling, housing support and help users begin the path to recovery through outreach from trusted staff.

Both the Center for Disease Control and National Institute of Health support the idea that NEP are a crucial aspect to a comprehensive approach to the opioid crisis.

However, a 2013 study has found that the use of blue lights are unlikely to deter drugs users from injecting in public washrooms and may increase drug use-related harm. Pill mill A "pill mill" is a clinic that dispenses narcotics to patients without a legitimate medical purpose. This is done at clinics and doctors offices, where doctors examine patients extremely quickly with a purpose of prescribing painkillers. These clinics often charge an office fee of $200 to $400 and can see up to 60 patients a day, which is very profitable for the clinic. Pill mills are also large suppliers of the illegal painkiller black markets on the streets. Dealers may hire people to go to pill mills to get painkiller prescriptions. There have been attempts to shut down pill mills. 250 pill mills in Florida were shut down in 2015. Florida clinics also are no longer allowed to dispense painkillers directly from their clinics, which has helped reduce the
