2,5-Dimethoxy-4-ethylamphetamine (DOET) is a psychedelic drug of the phenethylamine, amphetamine, and DOx families.[8][6][3][2] It is closely related to DOM and is a synthetic analogue of the naturally occurring phenethylamine psychedelic mescaline.[2][9] The drug acts as a selective agonist of the serotonin 5-HT2 receptors, including of the serotonin 5-HT2A, 5-HT2B, and 5-HT2C receptors.[10][11]

DOET was first discovered by Alexander Shulgin in the 1960s.[12] It was clinically studied at low and sub-hallucinogenic doses for potential use as a pharmaceutical drug acting as a "psychic energizer" by Dow Chemical Company in the 1960s.[12] However, its development was terminated after DOM emerged as a street drug and caused a public health crisis in San Francisco in 1967.[12][13] Nonetheless, DOET's effects at low doses were extensively characterized in small clinical trials.[2][4][14][15][5] The psychedelic effects of DOET at higher doses were subsequently described by Shulgin in his book PiHKAL in 1991.[6]

DOET is taken by mouth.[6][3][4] It has a slow onset of 1 to 3 hours, a delayed peak of 3 to 5 hours, and a dose-dependent and potentially very long duration of 5 to 20 hours.[6][16][2][3] Effects at low doses include mild euphoria, enhanced self-awareness, and talkativeness, among others.[2][3][4] Mild closed-eye visuals can also occur.[15][5] At higher doses, DOET produces psychedelic effects including heightened emotions, sensory enhancement, rich closed-eye visuals, and open-eye visuals, among others.[6][5] Physical effects include pupil dilation, increased heart rate, and increased blood pressure.[4][14][17]
