Drug: the story on HearLore

Drug

The word drug itself emerged from a mundane storage method rather than a mystical potion. In the 14th century, the term likely derived from the Middle Dutch word droge, meaning dry, referring to medicinal plants that were preserved as dry matter inside wooden barrels. This etymological root reveals how early medicine relied on the simple preservation of botanical matter before the era of modern chemistry. By the 1990s, Spanish lexicographer Federico Corriente Córdoba proposed an even older lineage, tracing the term to an early Romanized form of the Al-Andalus language, possibly transcribed as hatruka. This linguistic journey from dry barrels to ancient Iberian dialects illustrates how the definition of a drug has shifted from a physical state of preservation to a complex biological agent. The term has since become skunked with negative connotations, often serving as a synonym for illegal substances like cocaine or heroin, yet in medical contexts, the words drug and medicine remain interchangeable. This duality defines the modern struggle between healing and harm, where the same substance can be a life-saving cure or a destructive vice depending on intent and regulation.

The Personalized Medicine Revolution

A single drug may help only 4 to 25 percent of the people who take it, revealing a startling inefficiency in modern pharmacology. The activity of a drug often depends entirely on the genotype of the patient, meaning that a treatment effective for one individual might be useless or even dangerous for another. For instance, the drug Erbitux increases the survival rate of colorectal cancer patients only if they carry a specific mutation in the EGFR gene. Similarly, Vemurafenib is approved specifically for melanoma patients who possess a mutation in the BRAF gene. This genetic specificity drives the high cost of development, where phase III trials can cost between 100 million and 700 million dollars per drug. The financial risk of developing a medication that only works for a small genetic subset has motivated the field of personalized medicine. This approach seeks to develop drugs adapted to individual patients rather than relying on a one-size-fits-all model. The number of people who benefit from a drug ultimately determines whether the massive investment in drug trials is worth carrying out, forcing researchers to look deeper into the genetic code of humanity to unlock true efficacy.

Sacred Brews and Ancient Roots

For at least five thousand years, Native Americans have used peyote, a small spineless cactus, as a major source of the psychedelic mescaline. While most mescaline is now obtained from columnar cacti like San Pedro to protect the vulnerable peyote, the ancient tradition remains intact. Amazonian shamans utilize ayahuasca, a hallucinogenic brew, to achieve religious ecstasy and generate the divine within. The Mazatec people maintain a long and continuous tradition of using Salvia divinorum, a psychoactive plant, to facilitate visionary states of consciousness during spiritual healing sessions. In the Pacific Ocean cultures, the roots of the kava plant produce a drink that acts as a stimulant, sedative, euphoriant, and anesthetic. The Xhosa people regard Silene undulata as a sacred plant, using its roots to induce vivid and prophetic lucid dreams during the initiation process of shamans. These entheogens, defined as substances that generate the divine within, form the basis of many ethnic religions. The Rastafari movement uses marijuana, or ganja, as a sacrament in their religious ceremonies, while psychedelic mushrooms, commonly called magic mushrooms, have been used for centuries to alter consciousness for spiritual purposes.

Common questions

What is the origin of the word drug?

The word drug emerged from the Middle Dutch word droge meaning dry in the 14th century to refer to medicinal plants preserved as dry matter inside wooden barrels. Spanish lexicographer Federico Corriente Córdoba proposed an even older lineage tracing the term to an early Romanized form of the Al-Andalus language possibly transcribed as hatruka.

How effective are drugs for the general population?

A single drug may help only 4 to 25 percent of the people who take it revealing a startling inefficiency in modern pharmacology. The activity of a drug often depends entirely on the genotype of the patient meaning that a treatment effective for one individual might be useless or even dangerous for another.

Which plants have been used as entheogens by Native Americans and other cultures?

Native Americans have used peyote as a major source of the psychedelic mescaline for at least five thousand years while Amazonian shamans utilize ayahuasca to achieve religious ecstasy. The Mazatec people maintain a long and continuous tradition of using Salvia divinorum to facilitate visionary states of consciousness during spiritual healing sessions.

What are the health risks associated with methylphenidate or Ritalin?

At high doses this medication can become highly addictive leading to serious consequences including psychosis anxiety and heart problems. Intravenous use of methylphenidate can lead to emphysematous damage to the lungs a condition known as Ritalin lung.

When were the Single Convention on Narcotic Drugs and the Convention on Psychotropic Substances established?

The Single Convention on Narcotic Drugs was brought about in 1961 to prohibit the use of narcotics save for those used in medical research and treatment. A second treaty the Convention on Psychotropic Substances had to be introduced in 1971 to deal with newer recreational psychoactive and psychedelic drugs.

How are pharmaceutical drugs classified into groups?

The Anatomical Therapeutic Chemical Classification System assigns drugs a unique alphanumeric code that assigns it to specific drug classes within the ATC system. Another major classification system is the Biopharmaceutics Classification System which groups drugs according to their solubility and permeability or absorption properties.
