Organophosphate poisoning
Organophosphate pesticides are one of the top causes of poisoning worldwide, with an annual incidence of poisonings among agricultural workers varying from 3-10% per country.
Opioid epidemic
In the late 1990s, around 100 million people or a third of the U.S. population were estimated to be affected by chronic pain. This led to a push by drug companies and the federal government to expand the use of painkilling opioids. In addition to this, organizations like the Joint Commission began to push for more attentive physician response to patient pain, referring to pain as the fifth vital sign. This exacerbated the already increasing number of opioids being prescribed by doctors to patients. Between 1991 and 2011, painkiller prescriptions in the U.S. tripled from 76 million to 219 million per year, and as of 2016 more than 289 million prescriptions were written for opioid drugs per year. Mirroring the positive trend in the volume of opioid pain relievers prescribed is an increase in the admissions for substance abuse treatments and increase in opioid-related deaths. This illustrates how legitimate clinical prescriptions of pain relievers are being diverted through an illegitimate market, leading to misuse, addiction, and death. With the increase in volume, the potency of opioids also increased. By 2002, one in six drug users were being prescribed drugs more powerful than morphine; by 2012, the ratio had doubled to one-in-three. The most commonly prescribed opioids have been oxycodone and hydrocodone.
