Nitrous Oxide (Laughing Gas): The Science, History, and Controversy For over two centuries, nitrous oxide-commonly known as laughing gas-has captivated scientists, doctors, thrill-seekers, and policymakers alike. Once a parlor trick for 19th-century socialites, this colorless gas soon revolutionized the fields of anesthesia and dentistry. But alongside its medical marvels, nitrous oxide has also fueled underground recreational use, environmental concerns, and legal battles around the world. In Nitrous Oxide (Laughing Gas): The Science, History, and Controversy, author Ethan Sawyer takes readers on a gripping journey through the fascinating, and sometimes alarming, evolution of this gas. From its discovery by early chemists to its pivotal role in modern surgery, from the rise of recreational inhalation to the latest regulatory crackdowns, this book explores the delicate balance between scientific innovation and societal impact. How did a 19th-century chemist's experiments with nitrous oxide lay the foundation for modern anesthesia? What happens in the brain when inhaling nitrous oxide, and why does it create euphoria? Why is nitrous oxide increasingly targeted by law enforcement agencies, despite its common use in medicine and industry? How does this gas contribute to climate change, and what can be done about it? Combining scientific analysis, historical anecdotes, and cultural insights, Nitrous Oxide (Laughing Gas) provides a nuanced perspective on a substance that has shaped both medicine and popular culture. Whether you are a scientist, medical professional, historian, or simply someone intrigued by the curious intersections of medicine and human behavior, this book offers a deep dive into one of the world's most misunderstood gases.
