2C-B-FLY

Not specifically scheduled or controlled under federal law. However, the Federal Analogue Act may apply if the substance is sold or possessed with intent for human consumption, given its structural and pharmacological similarity to the Schedule I substance 2C-B.

Argentina's current individual-substances schedule retains 2C-B-FLY in Annex I, as substituted by Decree 122/2026; it is listed by name and chemical designation rather than controlled only through an analog or group definition. Article 2 of the underlying Decree 560/2019 treats substances in Annex I as "estupefacientes" for the ninth paragraph of Penal Code article 77. Decree 122/2026 was published on 2 March 2026 and entered into force the following day, so the current replacement annex—not the unqualified 2019 annex—is the operative schedule.

2C-B-FLY is covered in Austria as a phenethylamine derivative under Anlage II of the Neue-Psychoaktive-Substanzen-Verordnung. The annex covers every compound derivable from a phenethylamine core, including one with a heterocyclic or polycyclic ring system in place of the phenyl structure; this encompasses 2C-B-FLY’s tetrahydrofurobenzofuran-substituted phenethylamine structure. Under the Neue-Psychoaktive-Substanzen-Gesetz, producing, importing, exporting, supplying, or procuring a covered substance for psychoactive human use for gain is punishable by up to two years’ imprisonment, and the substance may be forfeited.

2C-B-FLY is listed by name in Annex IVB of Belgium’s Royal Decree of 6 September 2017 regulating narcotic drugs and psychotropic substances. The February 2023 amending decree inserted it into that annex, effective 17 March 2023. Importation, export, transport, manufacture, production, possession, sale, supply, dispensing, and acquisition of Annex IV substances require prior authorization; breaches are punishable under the Drugs Act.

2C-B-FLY is not named in Lista F2(a); it is covered by the generic phenethylamine structural class in Lista F2(d). The current ANVISA consolidated annex retains control of a 1-feniletan-2-amina bearing one or two furan, dihydrofuran, or tetrahydrofuran groups formed at adjacent ring carbons; PubChem identifies 2C-B-FLY as 2-(4-bromo-2,3,6,7-tetrahydrofuro[2,3-f][1]benzofuran-8-yl)ethanamine, which has that benzodifuran/phenethylamine arrangement. RDC nº 581 altered F2(d) and entered into force on 3 January 2022; later official updates, including the current version, retain the same operative class. The current F2(d) also excepts substances described nominally elsewhere in the regulation and registered-Anvisa medicines fitting items b–d; neither exception identifies 2C-B-FLY itself.

2C-B-FLY is a controlled substance in Schedule III of the Controlled Drugs and Substances Act because it is a 2C-phenethylamine with adjacent benzene-ring substitutions that form furan groups. Except as authorized by regulation, the Act prohibits its possession, trafficking, import or export, and production.

Chile classifies 2C-B-FLY as a narcotic or psychotropic substance capable of causing serious toxic effects or considerable harm to health under Article 1 of the Regulation of Law No. 20,000. The listing was added by Supreme Decree No. 220 of 2022, published on 13 September 2022. Unauthorized manufacture, preparation, extraction, importation, exportation, transport, acquisition, transfer, possession, supply, sale, or distribution of Article 1 substances is punishable under Law No. 20,000.

2C-B-FLY is controlled as a simple derivative of the listed substance 2C-B under Denmark’s Bekendtgørelse om euforiserende stoffer. List B substances may be used only for medical and scientific purposes; import, export, sale, purchase, supply, receipt, manufacture, processing and possession are permitted only under the regulation’s authorization rules. The current consolidated instrument takes effect on 29 March 2026.

Regulated under the Neue-psychoaktive-Stoffe-Gesetz (New Psychoactive Substances Act) since November 26, 2016.³⁴ Production and importation with intent to distribute, administration to others, and trading are criminally punishable.³⁴ Possession is prohibited but carries no penalty.

2C-B-FLY is a hallucinogenic substance and therefore falls within the Act's functional definition of a psychoactive substance, subject to the Act's exclusions. Ireland prohibits its sale or supply, and its import or export, where the actor knows or is reckless that it is being acquired or supplied for human consumption. This is not a blanket possession offence: section 3 does not prohibit simple possession, and the Act excludes a substance that is already a controlled drug. 2C-B-FLY is not a controlled drug in Ireland. It is named neither in the Schedule to the Misuse of Drugs Act 1977, consolidated to 29 July 2026, nor in any declaration order in force under section 2(2) of that Act. The designation order made under section 13 of that Act does not name it either.³⁷ The generic phenethylamine class, at paragraph 1A(l) of the Schedule and at paragraph 1(c) of the Misuse of Drugs Act, 1977 (Controlled Drugs) (Declaration) Order, 1987, which remains in force, reaches rings substituted with alkyl, alkoxy, alkylenedioxy or halo groups and further univalent substituents. Absence from those lists is not what puts 2C-B-FLY outside the controlled-drug regime: the class captures phenethylamines that Irish law never names, and 2C-B itself is controlled through it, its two methoxy groups and its bromine being alkoxy and halo ring substituents. Neither paragraph reaches 2C-B-FLY: its two fused dihydrofuran rings are divalent oxygen-to-carbon bridges, and the paragraphs admit alkylenedioxy bridges and otherwise only univalent substituents. No published Irish ruling applying either paragraph to a benzodifuran has been reported, so the position rests on the paragraphs' own wording. Ireland named the closely related benzodifuran Bromo-DragonFLY expressly in 2011, twenty-three years after the class entered Irish law. No order has been made excluding 2C-B-FLY from the 2010 Act, so its supply and importation fall under that Act rather than the Misuse of Drugs Acts.

Listed as a Schedule I controlled substance. Possession, production, sale, and purchase are illegal.

2C-B-FLY is a designated drug (指定薬物) under the Ministry of Health, Labour and Welfare ordinance, which lists it by its chemical name and salts; the Ministry’s current list records the designation date as 10 February 2016. Except for specified medical and other authorized purposes, Japanese law prohibits manufacturing, importing, selling, supplying, possessing, purchasing, storing, or displaying designated drugs and products containing them; the Ministry states that the general penalty is up to three years’ imprisonment, a fine of up to ¥3 million, or both.

2C-B-FLY is covered by the Netherlands' generic ban on substances derived from 2-phenethylamine because its tetrahydrobenzodifuranyl ring system and 2-aminoethyl side chain fall within the structure group in Lijst IA. Since 1 July 2025, the Opiumwet prohibits importing, exporting, preparing, processing, selling, supplying, transporting, possessing, or manufacturing a substance in that group or a preparation containing it. Intentional contravention is punishable by up to six years' imprisonment or a fifth-category fine.

2C-B-fly is listed in Norway's narcotics regulations as prohibited under section 5. The amendment's table identifies the substance by name without an international-control designation.

2C-B-FLY is controlled in Poland as a derivative of 2-phenylethylamine in group I-NPS. The statutory class expressly includes tetrahydrobenzodifuranyl ring systems and bromine substitution, which captures 2C-B-FLY's substituted tetrahydrobenzodifuran phenethylamine structure. Possession of a new psychoactive substance contrary to the Act is punishable by a fine.

Portugal lists 2C-B-Fly as a new psychoactive substance in the annex to Portaria n.º 154/2013, as republished by Portaria n.º 232/2022. Under Decreto-Lei n.º 54/2013, production, import, export, advertising, distribution, sale, possession, and making listed new psychoactive substances available are prohibited; the 2022 amendment entered into force on 8 September 2022.

2C-B-FLY is controlled in Russia under List I as a derivative of 2,5-dimethoxyphenethylamine, rather than through the separate analogue definition. List I covers narcotic drugs whose circulation is prohibited; the relevant generic entry was added by Government Decree No. 822 and excludes derivatives separately listed in the schedule.

Singapore's Misuse of Drugs Act 1973 captures 2C-B-FLY through its blanket psychoactive-substance regime rather than a substance-specific First Schedule entry. A psychoactive substance is one capable of stimulating or depressing the central nervous system and affecting mental functioning or emotional state when consumed; the Act's Part 2A regulates offences involving such substances, subject to the Fifth Schedule exclusions.

2C-B-FLY is a psychotropic substance listed as item 128 of Appendix 3 to the Enforcement Decree of the Narcotics Control Act. The Act prohibits unapproved possession, use, manufacture, import, export, sale, transfer, transport, and brokerage of a psychotropic substance in this category; the Ministry of Food and Drug Safety had already designated 2C-B-FLY as a temporary narcotic effective 26 August 2016.

Controlled substance as of April 2018. Possession, sale, purchase, and use are prohibited under Swedish narcotics legislation.

Turkey does not use a US-style schedule number for 2C-B-FLY; the substance is individually named in Annex 2 to Decision 2013/5742, which subjected 113 new psychoactive substances to Law No. 2313. Turkey's later generic-classification system, in use since 2015, controls qualifying chemical groups; 2C-B-FLY has no separate analogue classification, and none is needed because it is individually named. The 2025 EGM Narkotik report states that 1,078 NPS had been brought under Law No. 2313 during 2008-2024 through 31 July 2025 and that the EWS process continues to bring qualifying NPS under that law. The 2013/5742 entry has not been repealed or excluded, so the named listing remains the legal basis. TCK Article 188 penalties are conduct-specific: unauthorized manufacture, import or export carries 20-30 years' imprisonment, while trade-related conduct carries 10-20 years plus fines; TCK Article 191 use or possession for use carries 2-5 years, subject to the statutory deferred-prosecution, treatment and probation mechanisms. These ranges do not constitute one automatic sentence; authorization, facts, quantity and judicial findings can affect their application.

2C-B-FLY is not separately named in Ukraine's national controlled-substances list and is controlled as a derivative of the phenethylamine group under the note to List No. 2 of Table I. List No. 2 covers especially dangerous psychotropic substances whose circulation is prohibited; the statutory definition of circulation includes production, manufacture, storage, transport, acquisition, sale, import, export, transit, use, and destruction.

Controlled under the Psychoactive Substances Act 2016, which came into effect on May 26, 2016.⁸⁸ Production, supply, and importation are criminal offenses.⁸⁹ The compound was legally available on the open market prior to this blanket ban.

2C-B-Fly is expressly named, together with its chemical name, in the Annex to Decree 1130/2014; the original decree entered into force on 20 December 2014, rather than first adding it in 2015. The Annex was replaced by Decree 152/2025, effective 5 May 2025, and still expressly lists the exact substance. The later 2026 amendment removed only 4-BMC, 2-MMC and NEP from this consumer-market list for transfer to the narcotics decree, so it did not remove or reclassify 2C-B-Fly. Finland's Ministry of Social Affairs and Health states that manufacture, import, storage and placing these listed psychoactive substances on the consumer market are prohibited; this is distinct from the narcotics category.

2C-B-FLY has been expressly listed in Annex 4 of the Czech Government Regulation on lists of addictive substances since the 1 July 2022 amendment and remains in the current consolidated regulation. Its unauthorized possession in a small amount for personal use is an administrative offence under Act No. 167/1998 Coll. § 39(2)(e), while Criminal Code § 284 criminalizes unauthorized personal possession only in an amount greater than small. Accordingly, this decriminalized classification is limited to small-amount personal possession; it does not authorize supply, commercial dealing, import/export, or other unauthorized handling of the scheduled substance.
