Cocaine was first used therapeutically in 1884 for ophthalmologic procedures, accompanied closely by reports of severe toxicity. Amphetamines were synthesized in 1887, and in 1932, they were marketed medicinally in an inhaler form as a bronchodilator. Use of methamphetamine to enhance physical and intellectual performance began in the 1930s. Amphetamines were widely used as an alertness aid for troops by both Allied and Axis powers during World War II. Today, cocaine and amphetamines have limited therapeutic roles but are widely used as drugs of abuse. Clinical effects and toxicity are due to sympathetic nervous system stimulation.
