All of these forms of opioid remain relevant to the current crisis. And there are plenty of people who start on one and die on another. During the first phase, from the mids to about , there was a steady increase in deaths from prescription-opioid overdoses. Patient-privacy laws and a lack of coordination between US states meant that users could amass numerous opioid prescriptions and then sell their excess pills. This was a departure from the supply chain of previous epidemics, says Jonathan Caulkins, a drug-policy researcher at Carnegie Mellon University in Pittsburgh, Pennsylvania.
Rather than the supply being dominated by organized drug traffickers, users were responsible for the drugs entering the black market. This enabled the epidemic to spread quickly, he says. This did discourage abuse. But at the same time, for unclear reasons, the supply of heroin increased, and its price dropped sharply. Some opioid users switched to heroin because it was easier to obtain than prescription opioids.
Switching also enabled those who still had access to OxyContin to sell more of the higher-value prescription opioids on the black market. And data from the US National Center for Health Statistics show that between and , deaths from heroin overdoses increased almost fivefold in the United States. Around , the contours of the epidemic shifted for a third time.
Heroin dealers who wanted to increase profits began to mix their products with fillers and fentanyl. Because fentanyl is more potent than heroin, it is also more deadly. Other characteristics of the epidemic are also shifting. For example, there has been a surge in overdoses in black people. Many overdose deaths also now involve other substances as well as opioids.
In the face of a backlash in the United States and Canada, opioid manufacturers are increasing their activities elsewhere. An investigation in by the Los Angeles Times see go. Van Zundert thinks that most countries in Europe will avoid an opioid crisis. Doctors in the region are more likely to use milder opioids, such as tramadol, that are thought to pose a lower risk of overdose.
And Mundipharma has curtailed the marketing of opioids in Belgium, Van Zundert says. Yet opioid-related deaths are rising in countries other than the United States and Canada, including England, Wales, Ireland, Norway and Sweden, according to a report by the Organisation for Economic Co-operation and Development go.
None of these countries is facing problems on the scale of North America. The opioid crisis could also spread to lower- and middle-income countries, where opioids are rarely prescribed for pain associated with surgery, cancer or the end of life. Such countries therefore have a genuine need for improved pain treatments in the same way as did the United States in the lead-up to its epidemic.
With tight health-care budgets, these countries could be vulnerable to regulatory capture, a phenomenon in which governments come to serve the interests of the agents that they are meant to regulate, Humphreys says. For example, if a deep-pocketed pharmaceutical company offers to build a much-needed hospital, the government might be inclined to draft regulations that would loosen the supply of opioids in the country.

And as hard as the authorities in the United States are working to address the opioid crisis , the country could still be vulnerable to epidemics of other types of prescription drug. Some researchers are concerned that benzodiazepines, a widely used class of sedative, are being overprescribed. Excess pills are often shared with family members or friends — in a similar way to what happened early on in the opioid crisis.
But benzodiazepines are addictive and can be dangerous when mixed with other drugs. Certain aspects of the drug regulatory system in the United States leave the country exposed to such problems, says Caulkins. This prevented them from focusing on the potential for opioid misuse, and could have the same effect for other types of drug.
The FDA also evaluates drugs one at a time, rather than as families of semi-interchangeable molecules such as opioids. This has made it difficult to respond to the ever-increasing diversity of synthetic opioids.

It is also used postoperatively and for pain relief after childbirth. Percocet, Percodan, and Tylox are other trade name oxycodone products. Oxycodone is a central nervous system depressant. Oxycodone's action appears to work through stimulating the opioid receptors found in the central nervous system that activate responses ranging from analgesia to respiratory depression to euphoria.
People who take the drug repeatedly can develop a tolerance or resistance to the drug's effects. Thus, a cancer patient can take a dose of oxycodone on a regular basis that would be fatal in a person never exposed to oxycodone or another opioid.
