The public debate surrounding drug use has recently been stirred by narratives regarding the “return” or resurgence of heroin. These stories, often laden with apocalyptic imagery and comparisons to zombie films, have led to the declaration of national emergencies in countries like the United States. However, to understand the true magnitude of the problem, it is imperative to move past sensationalist headlines and engage in a critical reading that distinguishes between illicit heroin use and the epidemic caused by the misuse of prescription opioid painkillers. This analysis is situated within the realm of medicine and pharmacology, examining the history of these drugs, failures in the healthcare system, and the implications for public health.
In brief
- Crucial differentiation: It is vital to distinguish between heroin (an illicit drug) and prescription opioids (legal pharmaceuticals), even though both share mechanisms of action.
- Industrial role: The pharmaceutical industry developed molecules more potent than morphine to treat pain, but failed to completely eliminate the risk of dependence and euphoria.
- Mass prescription: The problem in the United States originated primarily from the excessive prescription of synthetic opioids (such as oxycodone) without adequate clinical justification.
- Deadly risk: Overdose with these drugs causes respiratory depression, making euphoria a serious and potentially fatal adverse effect if not managed correctly.
- European context: Unlike the U.S., Europe does not show conclusive data regarding a massive increase in heroin consumption, although media focus has generated unnecessary social alarm in some regions.
History and foundations: morphine as a therapeutic pillar
Active ingredients derived from opium have been fundamental in the history of human medicine. Morphine, discovered in the mid-19th century, quickly became the standard analgesic for managing severe pain and remains on the World Health Organization (WHO) list of essential medicines today. Its utility is undeniable: it allows for the relief of intense physical suffering that was previously unbearable.
However, like any potent drug, morphine presents unwanted side effects. These include constipation, nausea, blurred vision, and dry mouth. Furthermore, the body develops adaptation mechanisms known as pharmacological tolerance; this means that over time, higher doses are required to achieve the same analgesic effect. Simultaneously, physical dependence can arise, characterized by withdrawal symptoms upon abruptly stopping treatment and, in cases of overdose, fatal respiratory depression.
In responsible clinical practice, these effects are managed through specific formulations, progressive dose titration, and gradual withdrawal. The euphoria sometimes experienced by patients under treatment should not be considered a minor adverse effect; it is a real physiological response of the brain’s reward system which, while desirable in brief contexts, becomes a risk when medical necessity justifies it.
The pharmaceutical industry and the development of new opioids
For decades, industrial research focused on designing molecules that would multiply the analgesic effect of morphine, allow for alternative routes of administration (sublingual, intranasal, transdermal), and minimize adverse effects. The goal was clear: to offer superior pain relief without the disadvantages of traditional morphine.
The results were mixed. More potent drugs such as oxycodone, hydromorphone, and fentanyl (an extremely potent synthetic derivative) were indeed achieved, as were options like buprenorphine for maintenance treatments. However, in one critical aspect, progress was insufficient: the potential for dependence.
Drugs like oxycodone can induce euphoria similar to heroin, especially if administered via rapid routes (such as nasal injection after crushing tablets). Manufacturers had to reformulate products in the face of mass abuse cases where patients and doctors discovered how to alter the formulations to enhance the psychoactive effect. Although these medications are much more expensive than morphine, their cost does not guarantee absolute safety against misuse.
The U.S. case: between deregulated prescription and the current crisis
The situation in the United States perfectly illustrates how a public health problem can escalate into an epidemic. Between 2005 and 2015, opioid-related deaths increased significantly, while the number of regular users went from 200,000 to more than 600,000. This increase was particularly pronounced in women.
The main trigger was not necessarily illicit heroin, but the massive and disproportionate prescription of opioid painkillers by healthcare professionals. Dentists, orthopedists, and rheumatologists began prescribing oxycodone and fentanyl as if they were common medications, without adequately evaluating the risks of dependence or the available alternatives.
This phenomenon was aggravated by the availability of cryptomarkets and illegal derivatives that mimicked legal drugs but with unknown purity. The combination of increasing illicit production worldwide and a lax prescription system created the conditions for what we now call a “perfect storm.”
Terminological confusion: heroin vs. opioids
One of the greatest obstacles to understanding the crisis is the linguistic confusion between “heroin,” “opiates,” and “opioids.” Heroin is a specific opiate derived from natural opium, while the term “opioids” encompasses both synthetic and semi-synthetic drugs (such as fentanyl or methadone) used for medical purposes. Saying that “the heroin zombies are returning” is inaccurate if what is occurring is an overdose crisis caused by prescription medications.
This distinction is vital to avoid inadequate solutions. Attacking the problem as if it were solely a resurgence of street drug use ignores the structural root: the lack of control in medical prescribing and the cultural normalization of opioid use for chronic pain.
Harm reduction and critical reading
Faced with this complexity, it is essential to adopt a stance based on scientific evidence rather than unfounded fears. For anyone who uses or observes the use of opioids:
- Never mix opioids with central nervous system depressants (alcohol, benzodiazepines), as this drastically increases the risk of respiratory arrest.
- Store medications in secure, locked places, out of the reach of minors or vulnerable individuals.
- Never share prescription medication, even with family members, as individual doses vary according to metabolism.
- Seek professional help for signs of dependence: persistent nausea, anxiety about taking the drug, or increased tolerance.
- Know the available antidotes, such as naloxone, which can reverse a fatal overdose in minutes if administered in time.
The pharmaceutical industry has contributed to the problem with research that prioritized profitability over long-term safety. However, this does not imply that opioids are inherently “bad”; they are vital therapeutic tools for millions of patients with chronic pain or cancer. The challenge lies in balancing equitable access to pain treatment with strict measures to prevent abuse.
Future expectations and conclusions
The response to this crisis requires international coordination involving governments, healthcare systems, and civil society. Measures proposed by authorities such as the Office of National Drug Control Policy in the United States include educational campaigns, prescription restrictions, and substitution treatment programs. However, the most urgent task is to change the public narrative: stop viewing patients with dependence as “addicts” and start treating them as sick people who need specialized medical attention.
At Psiconáutica.org, we understand that the path toward a healthier society involves education, prevention, and harm reduction. Heroin has not magically returned; what we have seen is a multifactorial crisis where historical errors, economic interests, and social vulnerabilities converge. Only by addressing it with scientific rigor and empathy can we build a future where pain relief does not come at the price of life itself.
