Ley 23.737 · 2026
Argentina has not legalised cannabis. The 1989 drug law is still in force, but in 2009 the Supreme Court limited it for private use by adults. Here is what applies in Buenos Aires, as everywhere in Argentina.
Art. 14 of law 23.737 still punishes it (1 month to 2 years), but since the Arriola ruling (Supreme Court, 2009) punishing an adult's private use that harms no one is unconstitutional. Police can still seize it and open a case.
Using openly where others can see you can fall under art. 12 (2 to 6 years on paper). The Arriola protection covers private use only.
Growing is a crime (art. 5): 1 month to 2 years for a small grow for yourself. Only patients registered in REPROCANN with a medical indication can grow legally.
Selling: 4 to 15 years in prison. Giving a small amount for free, occasionally: 6 months to 3 years.
National traffic law 24.449 bans driving under the influence of drugs: fines and loss of your licence.
Legal since 2017 (law 27.350) for patients with a medical indication, through REPROCANN, which also allows home growing.
No coffee shops, no legal sales and no clubs open to everyone. Arriola is applied case by case. Uruguay's legal cannabis is only for registered residents, and taking it across the river is smuggling.
Quick tool
Montevideo is just across the River Plate, and many visitors think its legal cannabis rules also apply here. Pick a situation and compare. It is a guide, not legal advice.
In Argentina (Buenos Aires)
Still in the law, but courts should not punish an adult for a small amount kept for private use.
Across the river in Uruguay
Having a small amount for personal use is not punished in Uruguay.
Look after yourself
No. The law still punishes possession, but since the Arriola ruling (2009) courts should not punish an adult for a small amount kept for private use that harms no one. Selling, giving and smoking openly in public are still risky.
No. Uruguay's legal cannabis is only for registered residents, and taking it across the River Plate is smuggling in both countries.
The national register of medical cannabis patients (law 27.350). With a medical indication, registered patients can grow at home or through an authorised third party or organisation.
Cannabis oils, including CBD, are allowed for medical use with a prescription.
Giving cannabis, even for free, is a crime: 6 months to 3 years for a small, occasional gift, and 4 to 15 years if it counts as trafficking.
