    The history of methamphetamine involves key scientific breakthroughs in both Europe and Asia. In 1887, Romanian chemist Lazăr Edeleanu synthesized phenylisopropylamine, the compound now known as amphetamine, in a German lab. Shortly after in 1893, Japanese chemist Nagai Nagayoshi successfully synthesized methamphetamine. Nagayoshi achieved this by isolating ephedrine from the Chinese ephedra plant, a botanical stimulant used in traditional medicine for centuries, marking the transition from a natural plant extract to a potent synthetic substance.

    Before becoming associated with a global health crisis, methamphetamine and its derivatives were common pharmaceutical products. In the 1930s, these substances moved from the laboratory to the medicine cabinet via the Benzedrine inhaler. This product was widely marketed as an over-the-counter decongestant designed to treat stuffy noses and the common cold. It is a striking historical fact that a drug now known for societal destruction began its commercial life as a simple, accessible remedy for respiratory issues.

    Ephedrine served as the foundational building block for the creation of methamphetamine. Nagai Nagayoshi isolated ephedrine from the ephedra plant, which had been a staple of traditional medicine for a long time. By 1893, Nagayoshi used this isolated ephedrine to synthesize methamphetamine. This discovery, alongside Lazăr Edeleanu’s earlier work on amphetamines, created a new branch of pharmaceutical history that eventually evolved from medicinal curiosity to the potent substances discussed in modern society today.
