If a Doctor doesn't knuckle-under to the DEA's demands to quit prescribing these medications, they send field agents out to pore over the medical records of their patients, scrutinizing each and every patient who is prescribed substances on their "hit lists" and demand justification for each and every prescription they write. This is costly for Doctors who are already struggling under heavy patient loads, who have neither the time nor resources to withstand the inquisitions by DEA agents who use this tactic as a method of intimidating them into violating their "Hippocratic Oath" and cave-in to DEA demands. This practice of intimidation and fear has proven to be remarkably successful, and Family Practice physicians as well as some specialists have quit prescribing medications for their patients who do suffer from chronic pain and refer them to "Chronic Pain Clinics," birthing another "medical specialty" that is costing taxpayers millions, if not billions, of dollars per year. In attempting to corral the majority of those who require chronic pain care into separate medical practices to allow them to monitor these patients more effectively, the DEA has created the "Pill Mills" that now require even more taxpayer money to uncover and prosecute for illegally prescribing dangerous drugs to addicts who illegally "Doctor Shop" and visit multiple physicians to satisfy their own cravings and/or seek these prescriptions to sell on the streets; this is a threat to the health and safety of those who purchase these drugs and do not understand the danger that these substances pose to recreational drug users, who often underestimate their power and, inadvertently, pay the ultimate price for their ignorance by overdosing and losing their lives.
