    Key Points

    • Laudanum is a tincture of opium produced by mixing opium with alcohol and played a significant role in early pain management.
    • Laudanum was once used extensively for all kinds of medical conditions before the dangers of dependency on opioids were fully acknowledged.
    • The widespread use of laudanum has been virtually eliminated due to the high incidence of overdose and addiction to opioids.
    • By understanding laudanum, it will allow you to better address concerns about opioids and the critical need for effective, evidence-based treatment.
    • The mental health, physical health, and relational impacts of opioid use disorder are far-reaching; therefore, there are numerous efficacious treatment options available.

    Laudanum is a medication produced from opium and has a long and complicated history, which is essential to comprehending how society’s understanding of opioids has evolved. In past centuries, laudanum was regarded as a universal remedy for many medical issues, but today it is a powerful drug with the potential to cause addiction.

    In this article, you will learn what laudanum is, how it was used, the health effects of laudanum on society, and why laudanum is not used frequently today. Additionally, we will examine the potential for laudanum addiction and the treatment of addiction to opioids through modern, evidence-based (practical application of the findings of the best available current research) methods that support long-term recovery for individuals and the people they know affected by opioid use disorder.

    What Is Laudanum? Definition and Composition

    Definition

    Laudanum is a tincture of opium produced by dissolving opium in ethanol (or alcohol). Opium is produced from the sap of the opium poppy plant and contains many naturally occurring opioid compounds. Historically, laudanum usually contained approximately 10 percent opium by weight, which equates to roughly 1 percent morphine content.

    Today, opium tincture is referred to as laudanum and illustrates the chemical nature of laudanum, rather than the commercial name that laudanum once had.

    What Is Laudanum Made Of?

    In order to determine what the active ingredient in laudanum is, it is essential to define the chemical composition of laudanum. The active ingredients in laudanum include several opium alkaloids (such as morphine and codeine), which are combined with alcohol (ethanol) and dissolved in laudanum. Morphine can be administered orally or via intravenous, intramuscular, or subcutaneous injection. Codeine is typically administered orally. The alkaloid compounds in the drug interact directly with receptors to reduce pain and manage symptoms [1].

    Since the concentration of the active ingredient in laudanum varies significantly, laudanum has historically had a very high overdose risk compared to all modern pharmaceuticals that have a standard formulation.

    Origin of the Term

    The term “laudanum” is thought to derive from the Latin word laudare, meaning “to praise.” This is indicative of the high regard in which laudanum was held when it was first discovered.

    Historical Context of Laudanum

    Early Origins

    Laudanum was first made and used in the 16th century and subsequently gained extensive popularity throughout Europe, as it became recognized as the best way to treat pain and was considered a medical breakthrough.

    Widespread Use in the 17th to 19th Centuries

    During the 17th to 19th centuries, laudanum was widely used to treat a variety of illnesses and conditions. Some of the many conditions for which laudanum was prescribed included pain, cough, diarrhea, insomnia, anxiety, and to calm infants and children. While historians note that calming newborns with tinctures was a common but dangerous household practice, at the time it was considered safe [2, 3].

    Laudanum was available over the counter and was included as an ingredient in many pharmaceutical and household medicinal products (patent medicines). To the extent that individuals across all walks of life consumed laudanum, it is clear that dependence and unintentional misuse were present among all social classes.

    Transition to Regulation

    As medical professionals began to see signs of addiction and overdose, governments instituted more significant developments of attitudes towards laudanum and the regulation of laudanum. The first example of regulation was included in the 1914 Harrison Narcotics Act in the United States, which included drugs made from opium [4]. These regulations marked a turning point in how opioids were prescribed and monitored.

    What Is Laudanum Used For Historically?

    To better understand how laudanum was used, it is necessary to examine what we recognize today as modern medicine.

    Pain Relief

    Laudanum has historically been used to manage pain, and the morphine contained in laudanum was what made it so effective, but also was the source of its potential for establishing a dependence.

    Cough Suppression and Sedation

    Physicians and alternative practitioners utilized laudanum as a treatment to suppress excessive cough and to sedate patients. The sedative effect of laudanum is attributed to opioids’ depressing activity in the CNS (the brain and spinal cord), slowing breathing, and promoting drowsiness.

    Treatment of Diarrhea

    Laudanum has been historically used to treat severe diarrhea. In rare modern contexts, opium tincture may still be used under strict medical supervision for this purpose.

    Other Historical Uses

    Laudanum was used for insomnia and as a general treatment to alleviate pain and discomfort. However, as the practice became commonplace, many individuals had developed tolerance, meaning higher doses were needed to achieve the same effect.

    In modern medicine, laudanum is largely obsolete

    Modern Medical View of Laudanum

    Why Laudanum Is Rarely Used Today

    In modern medicine, laudanum is largely obsolete. Safer, more precise opioid medications and non-opioid alternatives are available. These newer treatments have standardized dosing and more straightforward safety guidelines.

    Is Laudanum Still Used?

    A common question is, is laudanum still used? In the United States, laudanum is classified as a Schedule II: High potential for abuse, which may lead to severe psychological or physical dependence. These drugs have a currently accepted medical use in treatment in the U.S. or a currently accepted medical use with severe restrictions. Today, laudanum is only prescribed in sporadic cases, typically for severe diarrhea that does not respond to other treatments.

    Regulatory Status

    The strict regulation of laudanum reflects lessons learned from its history. These controls aim to reduce misuse, dependence, and overdose risk.

    Side Effects and Health Risks

    Acute Side Effects

    Short-term side effects of laudanum may include nausea, constipation, sedation, and cognitive impairment.

    Overdose Risk

    One of the most serious dangers of laudanum is shortness of breath and respiratory depression (shallow breathing that leads to a buildup of carbon dioxide and a lack of oxygen), which is a slowed breathing rhythm that can result in a fatality [5, 3]. Since laudanum is highly concentrated, many small dosing mistakes can cause death from overdose.

    Comparison to Modern Opioids

    Compared to modern opioids, laudanum has less predictable dosing and greater risks associated with it, leading to increased chances of an accidental overdose when it is used without proper medical oversight.

    Laudanum and Addiction

    Addiction Potential

    Due to laudanum’s potent opioids and ability to create a physiological dependence in the brain after repeated exposure, people can have great difficulty ending their relationship with laudanum with additional support once the brain’s chemistry has changed.

    Signs of Dependence

    People can show signs of becoming dependent on opioids through intense cravings, increasing tolerance, withdrawal symptoms, and disruption of their daily lives, work, or relationships. Common withdrawal symptoms include anxiety and physical pain, gastrointestinal issues, and extreme discomfort [6].

    Historical Impact of Addiction

    Many people became dependent on laudanum without even realizing they were. It was viewed through a medical lens, and as such, the associated dangers were not considered. As a result, laudanum came to be abused long before the term Opioid Use Disorder was even established.

    Why Laudanum Is Dangerous Today

    Limited Medical Use

    Laudanum is no longer used for the treatment of pain or other common medical conditions due to the potency and risk of death from overdose.

    Opioid Epidemic Context

    The historical perspective of laudanum provides an essential foundation in understanding the ongoing opioid epidemic. There are significant public health implications associated with the chronic misuse of opioids, and many of today’s issues surrounding the prescribing of opioids and the need to establish comprehensive treatment.

    Cultural Myths

    Many people believe that natural products are safer than synthetic medications. However, laudanum demonstrates that a product derived from nature can be just as dangerous, particularly when it affects the CNS.

    Opioid Use Disorder and Treatment Pathways at SOBA NJ

    SOBA NJ, understands the impact of opioid addiction on both the individual and their family and how it often co-occurs with other mental health issues, such as depression, anxiety, and post-traumatic stress disorder (PTSD).

    Recognizing Opioid Use Disorder

    Patterns of misuse regarding laudanum are similar to those identified with other opioids, including loss of control over substance use, continued use or abuse despite adverse consequences, and difficulty stopping use.

    Evidence-Based Treatment Options

    At SOBA NJ, the mental health and addiction treatment provided to clients is evidence-based (the practical application of the findings of the best available current research), meaning that care options are based on the best available scientific research. According to the Centers for Disease Control, comprehensive clinical care for OUD typically includes FDA-approved medications like buprenorphine or methadone [7, 1].

    Integrated Mental Health Support

    Successful, safe recovery must address both mental health and substance use disorder concurrently. To achieve this, specific therapies such as cognitive-behavioral therapy (CBT) (a form of talk therapy that focuses on identifying and changing unhelpful behaviors) help recognize and change maladaptive behaviors. In contrast, dialectical behavior therapy (DBT) (a form of talk therapy that helps people manage intense emotions and behaviors) assists in managing overwhelming emotions and behaviors. These types of therapies are components of many comprehensive care plans.

    Laudanum: An Early Opioid

    Understanding laudanum is essential to understanding the evolution of opioid prescribing practices and establishing the need for safe, regulated medical care. At one time, laudanum was considered a “cure-all.” Today, laudanum is recognized as a potent and highly dangerous opioid that presents a risk for overdose and dependence. Even though it is not commonly used anymore, its historical use lays the groundwork for our current approaches to ensuring that we prescribe opioids safely and appropriately, and how we continue to treat individuals who are currently opioid dependent.

    If you or someone you know has an addiction to opioids or another underlying mental health issue, compassionate, evidence-based support can provide you with helpful information for taking the following steps on the road to recovery. SOBA NJ is here for you and the people you know, helping them along the way to recovery.

    Frequently Asked Questions About Laudanum

    Is laudanum still legally prescribed?

    Yes. Although laudanum is still legal in the United States, it is classified as a Schedule II substance due to its high potential for abuse, which may lead to psychological or physical dependence. These drugs have a currently accepted medical use in treatment in the U.S. or a currently accepted medical use with severe restrictions. It has a significantly higher potential for abuse and addiction. As such, the use of laudanum has been minimal and is only prescribed in very rare instances after all other therapeutic options have failed to provide relief.

    Did people really use laudanum for many conditions in the past?

    Yes, there were a multitude of medical purposes attributed to the use of laudanum, including but not limited to pain, cough, diarrhea, insomnia, anxiety, and other ailments. In fact, before the advent of prescription medications, the many household remedies that contained laudanum were easy to obtain without a prescription. However, during this time period, the detrimental impact of laudanum on the body through addiction and overdose had not yet been fully understood.

    What is the difference between laudanum and modern opioid medications?

    The main difference between laudanum and modern opioid medications is predictability and safety. Most modern opioids are manufactured with standard dosages and obvious guidelines for prescribing. In contrast, laudanum, which is an opium tincture, varies from bottle to bottle in terms of the degree of concentration, which is why it is much more challenging to control the dosage of laudanum accurately and safely, compared to many modern opioids, resulting in a much higher likelihood of overdose because of this unpredictability.

    Can laudanum cause overdose faster than other opioids?

    Yes. Laudanum is a very concentrated form of opiate mixed with alcohol; therefore, because of the concentration of laudanum and the number of different opiate alkaloids in the liquid, even a small error in dosing could be fatal due to the increased risk of respiratory depression, a dangerous slowing of breathing, thereby making it a unique risk compared to many modern-day opioid medications.

    Is the laudium drug the same as laudanum?

    The term “laudium drug” is often a typographical error or an informal reference to the drug laudanum. The correct reference is “laudanum”; laudanum refers explicitly to an opium tincture made by dissolving opium in alcohol. There is no separate medication or use of a “laudanum drug.”

    What are the main dangers of opium tincture misuse?

    The misuse of opium tincture has the potential to create opioid dependence, overdose risk, respiratory depression, cognitive impairment, and withdrawal symptoms. As laudanum affects the CNS, it has the ability to severely harm both mental and physical health, and severely limit daily functioning capabilities when used without any form of medical oversight [3].

    How does laudanum relate to today's opioid epidemic?

    The history of laudanum illustrates how opioid misuse can have a direct impact on public health [4]. In addition, the legacy of laudanum acts as a reminder of the continued need for adequate monitoring of prescription practices and to ensure individuals have access to evidence-based (practical application of the findings of the best available current research) treatment options and mental health services.
