The Creation of Methamphetamine
Methamphetamine was first invented in 1893 by a Japanese chemist, Nagai Nagayoshi, who succeeded in extracting this substance from ephedrine. In 1919, another Japanese scientist, Akira Ogata, found a way to synthesize methamphetamine in its crystalline form by combining ephedrine with red phosphorus and iodine.
The stimulant properties of methamphetamine were quickly recognized, leading to the drug being used for various medical and military purposes in the following decades. Today, methamphetamine is classified as a Schedule II drug, and its production and use are highly regulated.
The History of Methamphetamine
The history of methamphetamine spans over a century. After its invention in Japan, methamphetamine was introduced to the United States in the 1930s as a treatment for asthma, narcolepsy, and sinus inflammation. During World War II, both Allied and Axis forces provided their troops with methamphetamine to increase their alertness and stamina on the battlefield.
In the 1950s, methamphetamine became widely available to the American public in the form of injectable medication. The dangerous side effects of meth addiction became apparent soon after, prompting the U.S. government to pass the Controlled Substances Act in 1970 and classify methamphetamine as an illegal drug.
The Uses of Methamphetamine
Before the risks of methamphetamine became known, the drug was used to treat a variety of medical conditions thanks to its stimulating properties. It is still legal to use methamphetamine in the United States for medicinal purposes with a prescription—for example, meth is sometimes used to address the symptoms of ADHD or help patients struggling with obesity.
Unfortunately, most people who use methamphetamine today obtain it illegally. Substance users may turn to meth to experience its euphoric short-term effects—increased energy, reduced appetite, and improved mood—without being aware of the long-term consequences of meth addiction.
The Dangers of Methamphetamine
Misusing methamphetamine can lead to numerous physical and mental health problems. On a physical level, meth addiction is associated with dental issues (tooth decay), skin problems (acne and sores), and weight loss. Psychologically, meth use may result in anxiety, insomnia, confusion, and hallucinations.
Methamphetamine addiction is characterized by the inability to stop using the drug, withdrawal symptoms (from nausea to depression), and drug-seeking behavior that disrupts the life of the individual with substance use disorder, as well as their friends and family. If you suspect someone you love is abusing meth, pay attention to the changes in their appearance, behavior, and social life, and contact a professional addiction specialist for advice.
