5-MeO-DiBF, also known as 5-methoxy-N,N-diisopropyl-3-(2-aminoethyl)benzofuran or as 1-oxa-5-MeO-DiPT, is a psychedelic drug of the benzofuran family related to the psychedelic tryptamine 5-MeO-DiPT. [2] [1] [3] It is the analogue and bioisostere of 5-MeO-DiPT in which the indole nitrogen has been replaced with an oxygen atom, making it a benzofuran rather than tryptamine. [2] The drug has been sold online as a novel designer drug starting in 2015. [1] [4]
The dose of 5-MeO-DiBF has been given as 10 to 40 mg orally, with a light dose being 10 mg, a common dose being 20 mg, and a strong dose being 40 mg. [1] Its onset is said to be 45 minutes and its duration is variably said to be 4 to 9 hours. [1] In addition to oral administration, the drug may also be insufflated. [1] The effects of 5-MeO-DiBF have been reported to include psychedelic head space, tactile sensations and tingling, and increased sexual desire, among others. [1]
Analogues of 5-MeO-DiBF have been found to interact with serotonin receptors including the serotonin 5-HT1A and 5-HT2 receptors. [5] [6]
Analogues of 5-MeO-DiBF include the benzofurans dimemebfe (5-MeO-BFE), MiPBF (1-oxa-MiPT), 3-APB (1-oxa-AMT), and mebfap (5-MeO-3-APB; 1-oxa-5-MeO-AMT) and the tryptamine 5-MeO-DiPT, among others. [3] [2]
5-MeO-DiBF has been sold online as a designer drug and was first definitively identified in December 2015 by a forensic laboratory in Slovenia. [1] [4]
5-MeO-DiBF is not controlled under the United Nations 1971 Convention on Psychotropic Substances, so thus it has a legal grey area in many countries, but it's possible it could be illegal under so-called analogue acts if sold for human consumption.[ citation needed ]
The drug is a controlled substance in Armenia as of 2022. [7]
5-MeO-DiBF is not a controlled substance in Canada as of 2025. [8]
5-MeO-DiBF is not an explicitly controlled substance in the United States. [9] However, it could be considered a controlled substance under the Federal Analogue Act if intended for human consumption.
