The use of phenethylamines in the dance scene is now well established. Apart from amphetamine, the commonest phenethylamine encountered in clinical and forensic settings is 3,4-methylenedioxymethamphetamine (MDMA) commonly known as ecstasy. Other phenethylamines, which have similar effects are encountered, such as 3,4-methylenedioxyethylamphetamine (MDEA) and their use has resulted in death. We report two deaths associated with another less commonly encountered member of the group, N-methyl-1-(3,4-methylenedioxyphenyl)-2-butanamine (MBDB), also known as Methyl-J and Eden.
