Derived from its parent drug, amphetamine, which was originally used in nasal decongestants, methamphetamine was developed in the early 1900s as a more potent form of amphetamine. Compared to its parent drug, methamphetamine has longer-lasting and more harsh effects on the central nervous system. Because of their strength, methamphetamines have become widely misused in the US. Now, methamphetamine addiction is a pervasive problem, with 1.6 million people diagnosed with methamphetamine use disorder in 2022 alone.
