Use and effects
NsBT was briefly described by Alexander Shulgin in his 1997 book TiHKAL (Tryptamines I Have Known and Loved).[1] According to Shulgin, NsBT is active at a dose of 25 to 75 mg orally and has a short-lived duration.[1][2] Its effects included a generalized and somewhat diffuse intoxication, intellectual excitement, modest sensory enhancements, and "a lot of erotic horniness".[1] However, no "plus-three" ratings occurred on the Shulgin Rating Scale.[1]
Shulgin has said that along with N-tert-butyltryptamine (NtBT), it is one of only two N-mono-substituted tryptamines with known psychoactivity.[1] He also said that N-mono-substituted tryptamines might be GHB-like intoxicants devoid of psychedelic effects.[1] However, N-methyltryptamine (NMT) has been reported to produce psychedelic effects.[1][3][4]
