Drugs

PROHIBITED

Penalties for drug offenses in Argentina are severe even for small amounts, including long prison terms; drug-facilitated robbery (via bars or dating apps) is increasingly common.

Cannabis

PROHIBITED

Cannabis is illegal in Argentina - possessing even a small amount for your own use is a crime under article 14 of Ley 23.737, punishable by one month to two years in prison. In 2009 the Supreme Court ruled in "Arriola" that punishing an adult for private personal use was unconstitutional, but the Court said expressly that it was not ordering general decriminalisation, and the article is still in force - so it is a defence a judge may apply after an arrest, not a licence to carry. Medical cannabis is legal only through the REPROCANN registry, which requires an Argentine national-ID account and a locally registered prescribing doctor.

Possession for personal use: one month to two years in prison (Ley 23.737 art. 14, second paragraph). Possession not established as personal use: one to six years plus a fine. Growing plants where the small quantity shows it is for personal consumption: one month to two years; otherwise cultivation, supply or sale carries four to fifteen years (art. 5). A first-time user who is not dependent may, once only, have the sentence replaced by a mandatory educational measure lasting at least three months (art. 21).

Vaping / E-cigs

RESTRICTED

Argentina swapped its vape ban for a registration regime in May 2026, but the rules exclude most American gear: single-use pre-filled vapes may not be imported or sold at all, e-liquid must be under 20 mg/ml nicotine (US pods are usually 50), tanks are capped at 2 ml, and tobacco is the ONLY permitted flavour.

Resolucion 549/2026 sets no monetary penalty of its own and routes enforcement to Ley 26.687 and its implementing decree. Within the registration regime, falsity in the sworn declarations filed for any register category is classed as a fault of maximum gravity, removing the product from the register until it is brought into compliance and without prejudice to any other sanction applicable under the rules in force. No traveller-facing fine for personal possession or personal use is published in this resolution.

Tobacco

PROHIBITED

Argentina bans smoking in enclosed workplaces and enclosed public places, schools at every level, childcare and elderly homes, museums and libraries, cultural and sports venues, public transport, transport terminals, and petrol stations - plus a catch-all covering ANY other enclosed space open to the public. The trap for visitors: merely HOLDING A LIT cigarette is caught, because the law defines "consumo" as inhaling, exhaling, chewing, sucking OR keeping a tobacco product lit. Outdoor patios, terraces and balconies ARE exempt - except at health and teaching establishments, where university grounds are the only outdoor places carved back in. A roofed terrace usually does not qualify as outdoors.

Art. 32 a) verbatim: "Multa en moneda de curso legal, equivalente al valor al consumidor final de entre doscientos cincuenta (250) y un mil (1000) paquetes de veinte (20) cigarrillos de los de mayor precio comercializados en el pais... En caso de reincidencia dicha multa podra alcanzar un valor de hasta dos mil quinientos (2500) paquetes con las mismas caracteristicas." The smoking ban sits in Chapter VI (arts. 23-26), which art. 32 a) expressly reaches. NO PESO CONVERSION IS PUBLISHED HERE ON PURPOSE: the fine floats with the retail price of the most expensive 20-cigarette pack sold in the country, and no official source publishes that reference price - any dollar or peso figure would be invented. Enforcement in practice runs through the venue first: art. 23 final paragraph gives non-smokers the right to require the owner or manager to order the offender to stop, and the implementing decree escalates to refusing service and then calling the police. Art. 34 requires a sumario guaranteeing the right of defence before any sanction. Separately, in the City of Buenos Aires the individual-facing offences that were located concern throwing butts and smoking in playground areas of parks and plazas rather than smoking indoors - CABA texts were not read first-hand this run.
