Is 2C-B legal in Mexico?

Legal status

2C-B is not a controlled substance by name in Mexico. It is not named in article 234 of the Ley General de Salud, which prints the estupefacientes, and it is not named in any of the five groups of article 245, which prints the psychotropics. The first group prints several dimethoxy phenethylamines, and a reader who finds one of them can easily take it for this row. Article 246 lets the Secretaria de Salud add further psychotropic substances by lists published in the Diario Oficial de la Federacion, and the consolidated text records one such addition with the note «Sustancia adicionada por Acuerdo DOF 24-12-2018», so the printed lists are open. Every note the Diario Oficial published between 1 January 2019 and 21 September 2026 was checked for a later such acuerdo and none adds anything to article 245. That absence is stated against the Ley General de Salud as it stands after the decree published in the Diario Oficial de la Federacion on 15 January 2026, which reforms article 234 whole and article 245 fracciones I segundo parrafo, II and IV, read together with the Orden Juridico Nacional consolidated text to 7 June 2024 for the articles that decree does not touch, read as at 21 September 2026.

Consequences if caught

Where this row sits is settled by the fact that no printed entry carries it. The closest printed entry is brolamfetamina, given as «2,5-dimetoxi-4-bromoanfetamina.», which carries a bromine in the same position but is an amphetamine and not a phenethylamine. Article 479 gives this row no line: the table names eight narcotics and this is not one of them. Articles 475, 476, 477 and 478 all run on the narcotics listed in that table, and article 474 puts a narcotic outside it with the federal authorities, «El narcótico no esté contemplado en la tabla». The eight amounts recited below therefore belong to the eight narcotics the table names and not to this row. The two Ley General de Salud penalty articles that follow are printed here because the live cell printed them for every Mexican row. They run on the narcotics the table names, and this row is not one of them. Article 477 sets ten months to three years of prison, «Se aplicará pena de diez meses a tres años de prisión y hasta ochenta días multa al que posea alguno de los narcóticos señalados en la tabla». It applies to possession below one thousand times a table amount where the circumstances do not make it possession for supply. Its fine is up to eighty dias multa. Article 475 of the Ley General de Salud sets four to eight years of prison, in the words «Se impondrá prisión de cuatro a ocho años y de doscientos a cuatrocientos días multa». It applies to commerce or supply, even free of charge, below one thousand times a table amount. Its fine is two hundred to four hundred dias multa. Its second paragraph raises the prison term to seven to fifteen years where the person supplied is a minor or cannot resist, «se aplicará una pena de siete a quince años de prisión y de doscientos a cuatrocientos días multa», and the previous version of this cell called eight years the small-scale ceiling, so that figure is carried forward and corrected here rather than dropped. The federal code articles below are printed on the same carried-forward footing. Article 193 of that code names articles 237, 245 fracciones I, II and III and 248, and this row is in none of them. Article 194 of the Codigo Penal Federal sets ten to twenty five years of prison, «Se impondrá prisión de diez a veinticinco años y de cien hasta quinientos días multa». It applies to production, transport, traffic, commerce, supply or prescription of a narcotic without the authorisation the Ley General de Salud requires. Its fine is one hundred to five hundred dias multa. Article 195 sets five to fifteen years of prison. It applies to possession with one of those purposes. Its fine is one hundred to three hundred fifty dias multa. Article 195 bis sets four years to seven years six months of prison. It applies where possession cannot be so considered. Its fine is fifty to one hundred fifty dias multa. Article 196 raises the article 194 penalties by one half in the listed cases. Article 193 of the same code defines narcoticos in its first paragraph as those the Ley General de Salud determines, and in its second names a narrower set, «son punibles las conductas que se relacionan con los estupefacientes, psicotrópicos y demás sustancias previstos en los artículos 237, 245, fracciones I, II, y III y 248 de la Ley General de Salud, que constituyen un problema grave para la salud pública». This row is outside the set that second paragraph names, and no reading of the first paragraph was adopted here to put it back inside. Article 479 is not the controlled-substance list and is routinely misreported as one. It is a short table of eight maximum amounts used by articles 477 and 478 for strict, immediate personal consumption: opium two grams, heroin fifty milligrams, cannabis five grams, cocaine five hundred milligrams, LSD fifteen thousandths of a milligram, and MDA, MDMA and methamphetamine at forty milligrams or one tablet or capsule of not more than two hundred milligrams. Mexico has no death penalty for any offence, which article 22 of the Constitucion Politica de los Estados Unidos Mexicanos settles in the words «Quedan prohibidas las penas de muerte». Those figures are set out here because this row is placed outside that regime, so they are recorded as Mexico's published drug penalties and not as this substance's exposure.

If prescribed or medical

No Mexican medicine contains it and none ever has, so no prescription regime attaches to it by any route. No narcotics or psychotropics prescription route follows from the Ley General de Salud, because neither of its two lists reaches this row. The special duties articles 240 onward impose on estupefacientes are not engaged, and the group specific rules of articles 250, 251 and 252 have no group to attach to. Ordinary Mexican medicines and consumer regulation may still apply, and a foreign prescription evidences therapeutic purpose and nothing more.

Documentation

Carry nothing on the strength of this name alone on the drug-control side, because neither article 234 nor article 245 of the Ley General de Salud reaches this row. Ordinary customs, quantity and medicines rules still apply, and a prescription and labelled packaging remain the sensible thing to carry. The first group prints several dimethoxy phenethylamines, and a reader who finds one of them can easily take it for this row. The absence was established by reading the whole of the Ley General de Salud as it stands after the decree published in the Diario Oficial de la Federacion on 15 January 2026, which reforms article 234 whole and article 245 fracciones I segundo parrafo, II and IV, read together with the Orden Juridico Nacional consolidated text to 7 June 2024 for the articles that decree does not touch, read as at 21 September 2026.

Drug laws and enforcement change and vary within a country. This is not legal advice. Always confirm with Mexico’s embassy or official drug authority before traveling; penalties can be severe, including imprisonment.
