In 2025, the question of cannabis legality in Brazil is more relevant than ever. Between partial decriminalization and strict prohibitions, Brazilian legislation remains complex and constantly evolving. This article helps you understand the current state of cannabis laws in the country.
Historical context: The evolution of cannabis legislation in Brazil
Brazil has a complicated historical relationship with cannabis, influenced by cultural, political and international factors.
- 1930s : Under the influence of international conventions and US anti-drug policies, Brazil began to criminalize cannabis.
- 1938 : The law on narcotics officially banned the plant, classifying it as a dangerous substance.
- 2006 : Law No. 11.343 decriminalizes the possession of small quantities for personal use, but leaves a large margin of interpretation for law enforcement.
For decades, the lack of a clear threshold between personal use and trafficking has led to mass arrests and prison overcrowding, particularly affecting disadvantaged populations.
The legal framework for cannabis in Brazil in 2025
The decriminalization of possession for personal use
A major turning point occurred in June 2024, when the Federal Supreme Court (STF) decriminalized the possession of cannabis for personal use.
-
Defined threshold: 40 grams
The Court established that 40 grams or less is considered a quantity for personal use, thus distinguishing consumers from traffickers. -
Administrative sanctions instead of criminal prosecution
- Warning
- Community service obligations
- Drug awareness programs
However, this decision does not mean legalization:
- Possession of cannabis for personal use no longer carries a prison sentence.
- The cultivation, sale, or distribution of cannabis remains illegal and severely punished.
Drug traffickers still face 5 to 15 years in prison, as well as fines of up to 1.5 million reais.
Medical cannabis in Brazil
The medical use of cannabis is permitted under certain conditions in Brazil.
- 2015 : The National Health Surveillance Agency (Anvisa) authorizes the importation of cannabidiol (CBD) for specific treatments.
- 2019 : Anvisa allows the national production of cannabis-based medicines, reducing costs and facilitating access for patients.
Who will have access to medical cannabis in 2025?
By 2025, more than 50 companies are authorized to produce and market cannabis-based medicines. These treatments are prescribed for:
- Epilepsy
- Parkinson's disease
- Multiple sclerosis
- Chronic pain
Problems accessing treatments
- Not covered by the public health system (SUS)
- High cost of treatments, sometimes exceeding 2,000 reais per month
Patient associations are campaigning for these treatments to be reimbursed by the state, in order to allow equitable access to care.
The social and political implications of legalization
An intense public debate
Since the Supreme Court's decision in 2024, the legalization of cannabis has been at the heart of political discussions in Brazil.
-
Those in favor of legalization put forward several arguments:
- Reduction of the power of cartels and organized crime
- Creation of new jobs and economic opportunities
- Improving product quality and safety
-
Opponents raise several concerns:
- Possible increase in consumption among young people
- Risks to mental health (psychosis, addiction)
- Negative impact on vulnerable populations
A survey conducted in 2025 shows that 72% of Brazilians remain opposed to the legalization of recreational cannabis, although support for medical cannabis is growing rapidly.
The potential economic impact of full legalization
According to independent studies, regulated legalization of cannabis could:
- Create more than 300,000 direct and indirect jobs
- Generate billions of reais in tax revenue
- Funding public education and health programs
Are there international examples that serve as models?
Uruguay and Canada are often cited as examples of successful regulation of recreational cannabis.
Some experts believe that Brazil could draw inspiration from these models, but political divisions are hindering any legislative progress in the short term.
The future of cannabis in Brazil
Scientific research and cannabis cultivation
In February 2025, the Brazilian Agricultural Research Agency (Embrapa) launched a 12-year program to study cannabis cultivation and its industrial and medical applications.
The goal is to:
- Improving cannabis strains adapted to the Brazilian climate
- Establish regional production centers
- Encourage the development of new cannabis-derived medicines
This initiative could pave the way for wider legalization in the future.
Conclusion: What will the state of cannabis legislation in Brazil be in 2025?
- Cannabis is not yet legal in Brazil
- Possession for personal use (less than 40g) is decriminalized but remains an administrative offense
- Medical cannabis is permitted under certain conditions, but access to it is limited by its cost.
- Sales and cultivation remain illegal and severely punished.
The future of cannabis in Brazil will depend on many political, social, and economic factors. Pressure from social movements and scientific studies could encourage deeper reform, but the country is still far from full legalization.
If you are in Brazil, stay informed of the laws in force and respect local regulations to avoid any penalties.
