Seda, Piteira and Ice-o-lator: Inside Brazil’s Two Pre-Roll Cultures
Brazil’s consumption culture is deep, informal and highly specific. It even has its own vocabulary.
Seda and piteira
Seda is the everyday word for rolling paper, covering the different types of rolling papers used for hand-rolled cigarettes and cannabis. Piteira is the word for the tip, and it’s where Brazil diverges most visibly from Europe. Cardboard is the baseline, but reusable glass, wood and ceramic piteiras are genuinely mainstream. Tip design also influences airflow and draw resistance, both important parts of the science behind the perfect pre-roll. Every head shop sells them, and people treat them as personal objects rather than disposables.
The supplies trade is big business. In its 2025 yearbook on growshops, headshops and brands, the consultancy Kaya Mind sized the market at about R$967 million. Hand-rolling tobacco made up 65.2% of it, at R$630.3 million, and rolling papers the other 34.8%. Sedas aimed specifically at cannabis consumption accounted for R$138.4 million. [1]
A regulated market growing in parallel
The medical side has grown fast. Brazil reached 873,111 patients in 2025, a 30% increase on 2024, and the market generated R$970.9 million, according to Kaya Mind’s Medical Cannabis Yearbook 2025. [2] Brazil is another example of how cannabis legality by country can differ between medical access and recreational sales. Patients reach treatment through three routes:
| Access route | Patients (2025) | Share |
|---|---|---|
| Imports | 354,000 | 40.55% |
| Pharmacies | 293,000 | 33.6% |
| Patient associations | 226,000 | 25.85% |

The association route is worth watching. Brazil has 315 provider associations, 47 of which hold court authorization to cultivate, with 27 hectares planted. [4]
The 2026 ANVISA framework
In February 2026 ANVISA published a package of resolutions that redesigned Brazil’s medical cannabis framework. [5] Here is what each one does:
| Resolution | What it covers | In force |
|---|---|---|
| RDC 1.012 | Cultivation for scientific research, with no THC limit, by authorized institutions. [6] | 4 Aug 2026 |
| RDC 1.013 | Domestic cultivation for medical and pharmaceutical purposes. Full production chain, Special Authorization per establishment, THC ≤ 0.3%, legal entities only. [7] | 4 Aug 2026 |
| RDC 1.014 | A regulatory sandbox for non-profit patient associations to cultivate and produce under ANVISA supervision, for up to five years. [6] | On publication (3 Feb 2026) |
| RDC 1.015 | Manufacturing, import and sale of cannabis products. Replaces RDC 327/2019 and creates a five-year Sanitary Authorization. [7] | 4 May 2026 |
Two details matter for anyone thinking about inhalables. First, commercial domestic cultivation is capped at 0.3% THC and limited to companies. Second, recreational use remains prohibited. This is a pharmaceutical framework, not a consumer one.
Brazil has written traceability into the chain from the plant forward, before a consumer market even exists.
São Paulo vs Rio: opposite paths
Latin America’s two biggest consumer cities have gone in opposite directions.
São Paulo
São Paulo has developed a hash-and-tobacco culture that looks European on the surface but isn’t. Hand-rolling tobacco gets mixed with extractions, and ice-o-lator, a solventless hash produced using ice water and mechanical separation, has become the city’s reference extract rather than a niche connoisseur item. It belongs to the broader family of cannabis concentrates, which differ in texture, composition and production methods. The tip is a long cardboard piteira, noticeably longer than the standard tips sold in Europe or North America. That format hasn’t been normalized anywhere else in the world.
Rio de Janeiro
Rio runs the other way. It’s flower-forward, with a clear preference for no tobacco at all.
So a single country has one city building a sticky, solventless-extract-plus-tobacco format around an oversized tip, and another consuming dry flower clean. Those differences affect how pre-rolls are made, from material preparation and filling to tip handling. That calls for two production lines, not two recipes.
What this means for producers
- Pharmaceutical documentation from day one. The first compliant Brazilian products will be held to ANVISA standards, with authorization per establishment and traceability written into the chain from cultivation forward.
- Two material paths. Serving both São Paulo and Rio means handling sticky, extract-heavy mixes and dry flower on the same operation. For the flower-based formats, understanding how to choose an industrial cannabis grinder becomes relevant to preparing material with consistent particle characteristics before filling.
- A filter no cone supplier stocks by default. The long piteira is a format problem in its own right. Standard pre-roll sizes offer a useful reference, but producers would need to account for the longer tip when determining the finished product’s dimensions.
- Association-scale economics. The sandbox is built around non-profit associations, which means small, frequent batches rather than industrial runs.
Final part of the series: why all of this variety is an automation problem, not a labor problem.
Frequently asked questions
What is a piteira?
A piteira is the Brazilian term for a pre-roll filter tip. Cardboard is the baseline, but reusable glass, wood and ceramic piteiras are mainstream, and São Paulo favors a noticeably longer cardboard format than Europe or North America.
Is cannabis legal in Brazil?
Medical cannabis is regulated by ANVISA and available through imports, pharmacies and patient associations. Recreational use remains prohibited.
Can companies grow cannabis in Brazil?
Since 4 August 2026, RDC 1.013 allows legal entities with a Special Authorization to cultivate cannabis with up to 0.3% THC for medical and pharmaceutical purposes. Research cultivation without a THC limit is covered by RDC 1.012.
How many medical cannabis patients are there in Brazil?
Kaya Mind counted 873,111 patients in 2025, a 30% increase on 2024, in a market worth about R$970.9 million.
