Ethylamphetamine

Ethylamphetamine was used as an appetite suppressant in the 1950s but was not as commonly used as other amphetamine derivatives such as dextroamphetamine or benzphetamine, and went out of fashion once newer drugs such as phenmetrazine were introduced.

Ethylamphetamine is intermediate between amphetamine and methamphetamine in potency, and concerns about its abuse potential were a likely factor that it was not so widely used as other similar drugs.

Ethylamphetamine is still encountered as a drug of abuse on the black market, but is very uncommon.
