Amphetamine and methamphetamine are both pharmaceutical drugs used to treat a variety of conditions, and recreational drugs which are colloquially known as "speed." Amphetamine was first synthesized in 1887 in Germany by Romanian chemist Lazăr Edeleanu who named it phenylisopropylamine. Shortly after, methamphetamine was synthesized from ephedrine in 1893 by Japanese chemist Nagai Nagayoshi. Neither drug had a pharmacological use until 1934, when Smith, Kline and French began selling amphetamine as an inhaler under the trade name Benzedrine as a decongestant.
