in the 1990s, which led to the CDC ''Guideline for Prescribing Opioids for Chronic Pain'', 2016 and the resulting impact on medical access to prescription opioids "outside of active cancer treatment, palliative and end of life." Opioids initiated for post-surgical pain management have long been debated as one of the causative factors in the opioid crisis, with misuse/abuse estimated at 4.3% of people continuing opioid use after trauma or surgery. When people continue to use opioids beyond what a doctor prescribes, or when opioids are over-prescribed, whether to minimize pain or induce euphoric feelings, it can mark the beginning stages of an opiate addiction, with a tolerance developing and eventually leading to dependence, when a person relies on the drug to prevent withdrawal symptoms. Writers have pointed to a widespread desire among the public to find a pill for any problem, even if a better solution might be a lifestyle change, such as exercise, improved diet and stress reduction. Opioids are relatively inexpensive, and alternative interventions, such as physical therapy, may not be affordable. In 2017, around 100 million people or a third of the U.S. population was estimated to be affected by
chronic pain Chronic pain is pain that persists or recurs for longer than 3 months.https://icd.who.int/browse/2025-01/mms/en#1581976053 It is also known as gradual burning pain, electrical pain, throbbing pain, and nauseating pain. This type of pain is in cont ...

prescriptions in the U.S. tripled from 76 million to 219 million per year. In 2016, more than 289 million prescriptions were written for opioid drugs. This was exacerbated by the aggressive and misleading marketing of drug makers, e.g.

. Purdue trained its sales representatives to convey to doctors that the risk of addiction from OxyContin was "less than one percent." Mirroring the growth of opioid pain relievers prescribed was an increase in the admissions for substance abuse treatments and opioid-related deaths. This illustrates how legitimate clinical prescriptions of pain relievers were 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

. The epidemic has been described as a "uniquely American problem". The structure of the US healthcare system, in which people not qualifying for government programs are required to obtain private insurance, favors prescribing drugs over more expensive therapies. According to Professor Judith Feinberg in 2017, "Most insurance, especially for poor people, won't pay for anything but a pill." Prescription rates for opioids in the US are 40 percent higher than the rate in other developed countries, such as

pain, especially with post-pregnancy pain. The number of women who died from opioid pain relievers increased 5 times from 1999 to 2010. To help stop the spread of opioid abuse in women, it is advised that women are educated on the drugs that they are taking and the possible risk of addiction. Alternatives should always be used when possible in order to prevent addiction. Most research gone into understanding the epidemic is mostly focused on females, specifically anticipated mothers. Women are at the greatest risk for opioid addiction compared to men. Usually, opioid misuse in women stems from unused prescription drug hoarding, the dependence of the drugs and higher pain levels compared to men. Women are less likely to report opioid misuse in contrast to the male population. Analyzers of the epidemic stress that their main concern is the female victims, and studies tend to neglect the male population, when over 70% of prescription drug intake and overdose, happen to males. Adolescents can become easily addicted to opioids. Even before their teenage years, children go through the rapid growth of their reward center, the

. The development of the Mesolimbic pathway allows children to be easily satisfied by small rewards to encourage learning, motivation, and acceptable behavior. This growth peaks in their adolescent years, and they start to feel a need for larger, more meaningful rewards, such as psychoactive substances which produce reward signals through direct receptor binding. Teens have an underdeveloped

which governs impulse control and decision making. The combination of underdeveloped prefrontal cortex and a rundown reward system can lead to adolescents with addictive seeking behaviors and higher susceptibility to the neurological changes developed in substance use disorder (SUD). The

says that for every opioid death of a teen there are 119 emergency visits and 22 treatment admissions related to opioid abuse. Half a million teenagers in 2014 were reported as non medically prescribed opioid users and a third of those as having a substance use disorder (SUD). Family is widely discussed as an influence for factors affecting adolescent opioid misuse behavior and in the treatment of adolescent opioid misuse. Family involvement has been shown to be effective in decreasing substance use in adolescents by addressing family risk factors that may be contributing to an adolescent's substance use. Easy accessibility is a risk factor. The late 1990s, increases in opioid recommendations from pharmaceutical companies created an abundance of prescription painkillers in adult households. If family members are taking opioids for pains or have taken them in the past and did not dispose of them correctly or do not protect them properly, it can make it easy for adolescents to get their hands on them. Proper disposal of these drugs is crucial to reducing adolescent misuse. A national insurance cohort reviewed almost 90,000 opioid prescribed patients, 13–21 years old, and found that 5% continued to fill their prescription 90 days or more after surgery. Medicine take-back programs are the most recommended and regulated disposal method by the United States Drug Enforcement Agency, although, it is not guaranteed that the prescribed patient will comply with this recommendation. There are eight different at-home drug disposal products on the market but none of them is federal agency approved or in the process of being evaluated. The main concern of proper opioid disposal is trash and sewage disposal that create pharmaceutical pollution and still grants access for adolescents with substance use disorders. Youth are at a heightened risk of developing opioid addictions, and treating youth opioid use disorder is more difficult than it is for older individuals. A systematic review of the epidemiological literature has found that adolescents and young adults consistently have shorter retention times in medication treatments for opioid use disorder than do older adults. This is why it is important for schools to implement effective strategies and programs to teach young children about the dangers and consequences of opioid misuse. Although the retention time of adolescents is much lower than adults, educating them from a younger age on opioid misuse should help keep children away from these drugs. In 2018, there was a lack of appropriate treatments and treatment centers across the nation. In 2018, big cities like New York City were lacking in treatment services and health offices as well as small
rural areas In general, a rural area or a countryside is a geographic area that is located outside towns and cities. Typical rural areas have a low population density and small settlements. Agricultural areas and areas with forestry are typically descri ...
. Another reason the opioid epidemic is hard to combat is due to available housing being limited to recovering addicts. Having limited housing makes it easy for recovering substance users to return to the environments and relationships that promoted drug misuse. Jobs for recovering addicts can be difficult to find. Individuals with substance use disorders that have criminal records have a more difficult time finding jobs once they leave recovery. Having to combat job insecurity can lead to stress, which can cause someone to relapse. "Wraparound services", or programs that provide services for patients who have just come out of rehabilitation centers or programs, are rare to non-existent, and are a contributing reason as to why the opioid epidemic has gone on for so long.


Public policy response

The 2019 lawsuit filed by the state of Oklahoma against
Purdue Pharma Purdue Pharma L.P., formerly the Purdue Frederick Company (1892–2019), was an American privately held pharmaceutical company founded by John Purdue Gray. It was sold to Arthur Sackler, Arthur, Mortimer Sackler, Mortimer, and Raymond Sackler in 1 ...
was the first significant step in prompting public action toward ending the opioid epidemic. The state of Oklahoma argued that Purdue Pharma helped start the opioid epidemic because of assertive marketing and deceptive claims on the dangers of addiction. One of the marketing strategies was to redefine "substance use disorder" as "pseudo addiction". In 2019, Purdue Pharma agreed to settle and pay 270 million dollars to the state of Oklahoma that would go towards addiction research and treatment. The settlement could indicate a win for other states that have taken legal action against similar opioid manufacturers. Specifically, states like California are raising similar claims that Purdue Pharma marketed the drug Oxycontin as a safe and effective treatment, which led to the opioid crisis leaving thousands dead in California from opioid overdoses.


Treatment within legal landscape

Title II of the Comprehensive Drug Abuse Prevention and Control Act of 1970, otherwise known as the Controlled Substance Act, established five drug schedules to regulate and control their manufacture and distribution. In 2017, President Donald Trump officially declared the opioid crisis a "public health emergency." In 2018, the United States federal government enacted the SUPPORT Act which aims to help Americans gain access to opioid addiction treatment and help and reduce the amount of opioids prescribed. Other efforts include enacting legislation that provides funds from the Department of Health and Human Services to help support the creation and use of Syringe Services Programs. From 2019, legislatures have started to advocate for the implementation of supervised injection sites as another way to help the opioid crisis and reduce harm. In 2021, the United States Court of Appeals for the Third Circuit held that supervised injection sites violate the Federal Crack House Statute.


Safe injection sites

Safe injection sites, also known as supervised injection sites are designated facilities where individuals can use pre-obtained drugs under the supervision of trained medical staff. These sites are designed to reduce the health and societal impacts of drug use by providing a controlled, hygienic environment for drug consumption. The primary goal is to prevent overdose deaths through immediate medical intervention and to reduce the transmission of infectious diseases such as HIV and
Hepatitis Hepatitis is inflammation of the liver parenchyma, liver tissue. Some people or animals with hepatitis have no symptoms, whereas others develop yellow discoloration of the skin and whites of the eyes (jaundice), Anorexia (symptom), poor appetite ...
, by offering sterile injection equipment. These sites often provide a range of services, including access to addiction treatment, healthcare, and social support systems, acting as critical points of contact for individuals who might otherwise be disconnected from the healthcare system. The concept of safe injection sites first emerged in Europe during the 1980s, with

Despite the documented benefits and support from certain quarters, the establishment of safe injection sites in the US remains highly controversial. Opponents argue that these sites may enable drug use and attract crime, while proponents contend that the evidence from other countries demonstrates significant public health benefits.

France

A study of prescription opioid use in France over 2004-2017 found that the use of strong prescription opioids more than doubled over the period. There was a large increase in the use of oxycodone for chronic non-cancer pain, by nearly 20-fold. Prescription opioid-related hospitalizations increased from 15 to 40 per 1,000,000 population (+167%, 2000–2017). Heroin and methadone hospitalisations were much lower, increasing from 2.6 to 6.9 per 100,000, with all of the increase due to methadone use rather than heroin. Opioid-related deaths, including drugs of abuse, rose from 1.3 to 3.2 per 1,000,000 population (+146%, 2000–2015).

receive less than 0.2% of what they need. 90% of all the morphine in the world is used by the world's richest 10%. America's opioid epidemic has resulted in an "opiophobia" that is stirring conversations among some Western legislators and philanthropists about adopting a " war on drugs rhetoric" to oppose the idea of increasing opioid accessibility in other countries, in fear of starting similar opioid epidemics abroad. The International Narcotics Control Board (INCB), a monitoring agency established by the U.N. to prevent addiction and ensure appropriate opioid availability for medical use, has written model laws limiting opioid accessibility that it encourages countries to enact. Many of these laws more significantly impact low-income countries; for instance, one model law ruled that only doctors could supply opioids, which limited opioid accessibility in poorer countries that had a scarce number of doctors. In 2018, deputy head of China's National Narcotics Commission Liu Yuejin criticized the U.S. market's role in driving opioid demand. In 2016, it was reported that while Mexican cartels are the main source of heroin smuggled into the U.S., Chinese suppliers provide both raw fentanyl and the machinery necessary for its production.

. 90 people in Calgary overdosed on the drug in 2015. In 2016 in Southern California, a home-operated drug lab with six pill presses was uncovered by federal agents. Each machine was capable of producing thousands of pills an hour. In 2018, a woman died in London after getting a prescription for tramadol from an online doctor based in Prague who had not considered her medical history. Regulators in the UK admitted that there was nothing they could do to stop this from happening again. A reporter from The Times was able to buy opioids from five online pharmacies in September 2019 without any contact with their GP by filling in an online questionnaire and sending a photocopy of their passport.


Alternative for opioids

Alternative drug options for opioids include over the counter pain medication such as Ibuprofen, Tylenol (acetaminophen/paracetamol), and Aspirin or steroid options. A German study comparing legal opioid use between different countries concluded that a high consumption of oxycodone could be attributed to the non-availability of the drug metamizole, a non-opioid pain reliever which is heavily used in some countries such as Germany and Austria, but which is banned in others such as the US and Canada. Along with drug alternatives, many other alternatives can provide relief through physical activities. Physical therapy, acupuncture, injections/nerve blocks, massages, and relaxation techniques are physical activities that have been found to help with chronic pain. New pain management drugs like Cannabis (drug), cannabis and cannabinoids have also been found to help treat symptoms of pain. Many treatments like cancer treatments are using these drugs to help manage pain.


Signs of addiction

People that are addicted to opioids can have many changes in behavior. Some of the common signs or symptoms of addiction include spending more time alone, losing interest in activities, quickly changing moods, sleeping at odd hours, getting in trouble with the law, and financial hardships. People that notice any of these behaviors in a peer or in oneself, are usually advised to consult a physician.


Treatment and prevention of addiction

Opioid use disorder can be treated in a number of different ways: Medication assisted treatment pathways offer methadone, Suboxone (Buprenorphine/naloxone) and Vivitrol (naltrexone), though naltrexone has poor treatment outcomes due to low patient retention. According to the 2017 Surgeon General's report, medication (buprenorphine/methadone) assisted therapies (MAT's) remain the gold standard in evidence-based care for opiate addiction, with the highest reduction in morbidity, mortality, and general negative outcomes achieved through long term opioid replacement therapy. The report makes recommendations concerning expanding access to MAT in order to combat the opioid epidemic. Social stigma regarding medication-assisted treatment in nations like the USA have been a major barrier in implementing evidence based treatments for opiate addiction. Cognitive behavioral therapies and counseling are proven effective (though less efficacious on their own than medication assisted therapies) as well as digital care programs to increase abstinence rates. A number of methods for the prevention of opioid addiction have been used and suggested. One method is the creation of anti-opioid advertisements. In the 1990s, advertisements depicting drug-seeking people purposefully slamming their arms into doors and crashing their cars, were unsuccessfully targeted at teens. These ads were unsuccessful because they emphasized the risk of danger, pain, and death caused by opioids. While this tactic would make adults acknowledge the risks and stop using opioids, for many teenagers, the perceived danger adds to the appeal, as smoking becomes a form of rebellion against authoritative adults. When ads were created that instead channeled teenage rebellion toward resisting the tobacco industry's manipulative tactics, the numbers of teens smoking went down. The makers of these ads feel that since the internet allows teenagers to view gruesome things anyway, it is perfectly acceptable to subject them to images of self-mutilation in order to protect their lives. It is felt that thirty seconds of gruesomeness is a small price to pay for sparing a lifetime (however short) of opioid abuse and its accompanying poverty and crime. These advertisements, which started in the 1980s, are continuing to play on television today, utilizing donated advertisement time. The goals of the most recent advertisements are to show teenagers that addiction can begin after only five days, and that feeding this addiction can consume a person's entire life.
