The rules vary by state but MDs, DOs can inject botox anywhere in the United States. In some states Nurse practioners are allowed to inject botox. As long as someone is familiar with the anatomy, it should be fine. Remember, botox wears off in 3-4 months so the risks are relatively small. There are small risks however and I have had to treat patients treated by surgeons, nonsurgeons and nonphysicians who have trouble closing their eyes after overaggressive botox. Granted these patients are rare but it is a possibility in untrained hands.
A July 2013 study by US Geological Survey scientist William Ellsworth links earthquakes to wastewater injection sites. In the four years from 2010-2013 the number of earthquakes of magnitude or greater in the central and eastern United States increased dramatically. After decades of a steady earthquake rate (average of 21 events/year), activity increased starting in 2001 and peaked at 188 earthquakes in 2011, including a record-breaking -magnitude earthquake near Prague, Oklahoma which was the strongest earthquake ever recorded in Oklahoma. USGS scientists have found that at some locations the increase in seismicity coincides with the injection of wastewater in deep disposal wells. Injection-induced earthquakes are thought to be caused by pressure changes due to excess fluid injected deep below the surface and are being dubbed “man-made” earthquakes.  On September 3, 2016, a -magnitude earthquake occurred near Pawnee, Oklahoma , followed by nine aftershocks between magnitudes and within three and one-half hours. The earthquake broke the previous record set five years earlier. Tremors were felt as far away as Memphis, Tennessee , and Gilbert, Arizona . Mary Fallin , the Oklahoma governor, declared a local emergency and shutdown orders for local disposal wells were ordered by the Oklahoma Corporation Commission.   Results of ongoing multi-year research on induced earthquakes by the United States Geological Survey (USGS) published in 2015 suggested that most of the significant earthquakes in Oklahoma, such as the 1952 magnitude El Reno earthquake may have been induced by deep injection of waste water by the oil industry. 
ENBREL is a medicine that affects your immune system. ENBREL can lower the ability of your immune system to fight infections. Serious infections have happened in patients taking ENBREL. These infections include tuberculosis (TB) and infections caused by viruses, fungi, or bacteria that have spread throughout the body. Some patients have died from these infections. Your healthcare provider should test you for TB before you take ENBREL and monitor you closely for TB before, during, and after ENBREL treatment, even if you have tested negative for TB.
