Expo Cannabis Argentina is the country’s major cannabis fair and one of the best attended in Latin America: its first edition, in 2019, drew 56,000 visitors according to La Nación. It brings together industry, cultivation, health and culture, with an unusual feature: families are part of its intended audience too. The 2027 edition has not yet been announced. In the meantime, here is what is useful to know.

When is Expo Cannabis 2027?

As of 1 November 2026, the organisers have not announced a date or venue for 2027. The seventh edition has just taken place, from 23 to 25 October 2026, at La Rural in Palermo.

The fair usually takes place in October or November, but the venue is not fixed: the 2025 edition was held at Centro Costa Salguero, and it returned to La Rural in 2026. That is why we cannot confirm a venue for 2027. Once the announcement is made, we will add it to the calendar.

Visitor rules and Argentina’s legal framework

All ages. Minors must be accompanied by a responsible adult.
No smoking or alcohol. All pavilions are smoke-free, and bringing in, consuming or selling alcohol is prohibited throughout the grounds.

The law. Medicinal use is regulated by Law 27.350, and the REPROCANN register permits cultivation on medical advice within limits on plant numbers and growing area. Adult use has not been legalised: Law 23.737 remains in force. The sources we consulted on this framework date from 2021 and 2022, so any subsequent changes should be checked.
