5-Thioasymbescaline (5-TASB), also known as 3,4-diethoxy-5-methylthiophenethylamine, is a psychedelic drug of the phenethylamine and scaline families related to mescaline.^[1][2][3][4] It is the analogue of asymbescaline in which the methoxy group at the 5 position has been replaced with a methylthio group.^[1][2][3][4] The drug is one of three possible thioasymbescaline (TASB) positional isomers, the others being 3-thioasymbescaline (3-TASB) and 4-thioasymbescaline (4-TASB).^[1][2][3][4]

In his book PiHKAL (Phenethylamines I Have Known and Loved) and other publications, Alexander Shulgin lists 5-TASB’s dose as approximately 160 mg orally and its duration as about 8 hours.^[1] The drug has been variously described as having lower potency than mescaline to having twice the potency of mescaline.^[4][2][3][1]

The effects of 5-TASB have been reported to include hints of strangeness, neurological hyperactivity, slight physical effects, extremities feeling warm, slight lightheadedness, slight hyperreflexia, slight diarrhea, and extended physical malaise.^[1][3][4] It was said that there was more physical than mental and that it was not all entirely nice.^[1] In addition, it was said that the effects are real, but the person didn’t want to go any higher.^[1] It was concluded that the drug’s somatic effects overshadowed the psychological effects.^[1] Besides hints of strangeness, no hallucinogenic or other perceptual effects were described.^[1]

The chemical synthesis of 5-TASB has been described.^[1][4]

5-TASB was first described in the scientific literature by Shulgin and Peyton Jacob III in 1984.^[4] Subsequently, it was described in greater detail by Shulgin in PiHKAL in 1991.^[1]
