4f-MPH

4F-MPH falls within the generic structural definition for compounds derived from 2-phenethylamine in Anlage 1 Nr. 1 of the Neue-psychoaktive-Stoffe-Gesetz (NpSG). Section 3 prohibits trade, placing on the market, manufacture, import, export, transit, acquisition, possession, and administration to another person, subject to exceptions for recognized commercial, industrial, scientific, and specified official uses. Under section 4(1), trade, placing on the market, or administration to another person, as well as manufacture or import for the purpose of placing it on the market, is punishable by imprisonment for up to three years or a fine; simple acquisition or possession is not enumerated as a standalone offense in that provision. The NpSG excludes substances controlled under the Betäubungsmittelgesetz and qualifying medicinal products, veterinary medicinal products, and specified medical devices.

4F-MPH is expressly listed as 4-Fluormethylphenidat, 4F-MPH, and Methyl-2-(4-fluorphenyl)-2-(piperidin-2-yl)acetat in item 196 of Annex 6, Verzeichnis e. Under BetmKV Article 3(2)(e), Verzeichnis e materials and products are subject to the control measures applicable to Verzeichnis a narcotics, and BetmG Article 7 requires authorization from the Federal Department of Home Affairs for their cultivation, manufacture, import, export, storage, use, or placing on the market. BetmG Article 20(1)(c) makes those acts without authorization punishable by up to three years' imprisonment or a monetary penalty.

4-Fluoromethylphenidate (4F-MPH) is prohibited in Turkey. The annex to Presidential Decision No. 1335 of 19 July 2019 expressly lists 4-fluoromethylphenidate (4F-MPH) as methyl 2-(4-fluorophenyl)-2-(2-piperidyl)acetate and subjects it to Law No. 2313 under article 19; the decision was published in Resmî Gazete No. 30837 on 20 July 2019 and states no separate commencement clause. Turkish Penal Code article 188 prescribes twenty to thirty years' imprisonment and a judicial fine of 2,000 to 20,000 days for unauthorized manufacture, import, or export, and at least ten years' imprisonment and a judicial fine of 1,000 to 20,000 days for unauthorized domestic sale, offering for sale, supply, dispatch, transport, storage, purchase, acceptance, or possession. Article 191 prescribes two to five years' imprisonment for purchasing, accepting, or possessing the substance for personal use, or using it.

4-Fluoromethylphenidate has been expressly listed as a Class B drug in Schedule 2 Part II of the Misuse of Drugs Act 1971 since 31 May 2017. The Act makes its production, supply, and possession unlawful, subject to regulations under section 7 and to the applicable offence provisions and defences.

Schedule I(f) also covers the listed substance's salts, isomers, and salts of isomers when those forms can exist, unless specifically excepted. The DEA controlled-substances list dated August 27, 2026 does not name 4-Fluoromethylphenidate, 4F-MPH, or 4-FTMP, but an unlisted substance may still be regulated federally as a controlled-substance analogue when 21 U.S.C. §§ 802(32) and 813 apply.

4F-MPH is expressly listed in Tabella I as methyl (4-fluorophenyl)(piperidin-2-yl)acetate and 4-fluoromethylphenidate, effective 2 November 2021. Under article 73 of D.P.R. 9 ottobre 1990, n. 309, unauthorized production and sale are criminal offences, as are unauthorized import, export, purchase, and possession when the substance is intended for use that is not exclusively personal. Under article 75, illicit import, export, purchase, receipt, or possession for personal use is an administrative offence rather than a criminal offence. Activities authorized under article 17 are outside article 73's unauthorized-conduct offences.
