News reports regarding a potential resurgence in opioid use, with diacetylmorphine (heroin) taking center stage, are a recurring theme. However, behind these alarmist headlines lies a complex reality that requires careful unraveling with scientific rigor and ethical prudence. “Horse” remains the quintessential symbol of social harm in our collective memory, but understanding its current role requires us to distinguish between the pharmacological properties inherent to the substance and the consequences derived from inadequate public policies.
In brief
- Conceptual differentiation: The term “drug” is inherently ambiguous; the real distinction lies in the context of use (therapeutic vs. recreational), not in the chemical molecule itself.
- The weight of stigma: Heroin carries a historical stigma rooted in the health traumas of the 1980s and 1990s, which often obscures an objective analysis of its current risks.
- Evidence on harm reduction: Programs such as needle exchanges and substitution therapy (methadone/buprenorphine) are cost-effective measures backed by international organizations to reduce viral transmission.
- Cause vs. consequence: Increased consumption is not an inevitable consequence of the molecule, but frequently the result of failures in health policy and access to regulated treatments.
Definitions and perceptions of psychoactive substances
Public discussion about drugs usually begins with a confusing definition. In clinical and legal practice, there is a tendency to label any psychoactive substance not prescribed for therapeutic purposes as a “drug.” This dichotomy creates paradoxes: a medication approved for multiple sclerosis (nabiximols) has the same legal status as an illicit substance, even if its chemical composition differs from other recreational drugs. Similarly, drugs like methylphenidate are essential in pediatric psychiatry, while minimal doses of synthetic analogs can be grounds for customs detention.
Social perception tends to normalize certain habits: the consumption of alcohol, tobacco, or caffeine is considered part of a modern lifestyle. However, from a rigorous pharmacological perspective, all these substances are drugs with the potential for dependence and systemic effects. The distinction society makes between “drugs” (heroin, cocaine) and “normal substances” (alcohol, tobacco) does not respond to scientific criteria regarding toxicity or addiction, but rather to moral and cultural factors and the phenomenon of stigma.
The stigma of heroin: A persistent historical trauma
While cannabis is perceived by many young people as a low-risk substance, heroin occupies a unique place in the collective imagination. This status is due to the devastating effects observed during the 1980s and 1990s. In those years, unregulated intravenous use led to epidemics of HIV and hepatitis C, saturating hospital services with young, emaciated patients.
This period left an indelible mark: pharmacies guarded by private security, urban legends about discarded needles, and widespread social fear. Although some historical accounts have been questioned later (such as the alleged deliberate distribution of heroin in the Basque Country), the actual damage was massive. Overdose deaths and opportunistic infections defined a generation, creating a narrative where heroin is synonymous with premature death and social degradation.
Current problems: Crisis or systemic failure?
Globally, reports from organizations such as the United Nations Office on Drugs and Crime (UNODC) confirm that opioids remain a critical threat. Data indicate a high risk of fatal and non-fatal overdoses, as well as a high prevalence of infectious comorbidities among people who inject drugs.
It is crucial to analyze the cause-and-effect relationship in this context. Diacetylmorphine possesses pharmacological properties that confer a high potential for dependence and tolerance, with a narrow therapeutic margin. However, attributing the entire problem to the molecule ignores determining external factors. Increased consumption is not an unavoidable biological consequence, but frequently the result of restrictive policies that limit access to alternative treatments and drive up prices on the black market.
The difference between cause and consequence
Current international policies, dictated by UN conventions, have prioritized absolute prohibition over public health-based approaches. This strategy has led to situations where people who were dependent on prescription painkillers (synthetic opioids) seek cheaper and more accessible alternatives on the illegal market, such as heroin or fentanyl.
By restricting access to methadone or buprenorphine maintenance treatments in certain countries, users are forced into unsafe practices. Scientific evidence shows that sharing consumption equipment is the primary factor in viral transmission (HIV, hepatitis C), not the substance itself. A clean syringe can prevent infections regardless of the drug used.
The need to change drug policies
From an ethical and legal perspective, the current prohibitionist approach conflicts with fundamental principles such as the right to health. The Universal Declaration of Human Rights establishes that everyone has the right to the enjoyment of the highest attainable standard of physical and mental health. When public policies ignore robust scientific studies to impose ideological or political criteria, it constitutes moral negligence.
Organizations such as the International Narcotics Control Board (INCB) systematically express their concern regarding the failure of these measures. Despite international warnings, many states maintain prohibitions that prevent access to substitution therapies or harm reduction programs.
Practical examples and the efficacy of harm reduction
The evidence is conclusive: needle exchange programs are a cheap and highly effective intervention to reduce the prevalence of HIV and hepatitis C in populations that inject drugs. Similarly, therapies with methadone or buprenorphine have been shown to stabilize chronic use and improve the patient’s quality of life.
The Cochrane Database, a global leader in systematic reviews, has confirmed that treatment with pharmaceutical heroin (heroin-assisted treatment) improves clinical outcomes in dependent patients. Although this approach is politically controversial, from a medical point of view, treating dependence with the same substance under strict control drastically reduces mortality and associated crime.
In Spain, for example, the late implementation of needle exchange programs in prisons (only five penitentiary centers offered them in the year 2000) reflects a cultural resistance to accepting that consumption occurs within the prison system. This denial has an unacceptable human cost.
Conclusions and warnings about the future
The international landscape shows a generalized repugnance toward drugs, but also a disconnect between epidemiological reality and government actions. Despite recognizing an increase in consumption and associated problems, many measures focus on controlling production without addressing demand or offering viable therapeutic alternatives.
It is imperative to distinguish between the intrinsic danger of a substance and the consequences of its inadequate regulation. Heroin is not a biological weapon, but it is a drug with significant risks if used without medical supervision. However, the greatest risk comes from the illegal market: indeterminate purity, toxic adulterants (such as fentanyl), and a lack of hygiene.
For modern medicine, the challenge is to humanize health policies. This implies recognizing that opioid dependence is a treatable chronic disease, not a moral crime. Awareness of the risks must be accompanied by universal access to evidence-based treatments, without stigma or unnecessary legal barriers.
At Psiconáutica.org, we will continue to analyze how culture, science, and policy converge to define the future of substance use. The next part of this analysis will delve into the real motives behind the current resurgence of heroin in developed countries and evaluate whether new dynamics justify the concern or if it is once again a foreseeable consequence of current policies.
