Practical guidance
Avoid cross-border transport of cannabis products. Do not assume informal tolerance equals legality.
Legislative Background
Brazil's Supreme Court has decriminalized personal possession and private home cultivation, treating them as non-criminal acts distinct from trafficking. Medical cannabis products are regulated and available via prescription or authorized imports for patients with approved conditions, while commercial sales outside this framework remain prohibited.
Law Enforcement
“Always watch for the police. They’ll want to find you doing something to get some money out of you!” I felt officers were especially alert for gringos smoking. People claimed a few dollars would resolve a stop, but that was no guarantee. The newer Marijuana Laws section covers Brazil’s later change in how personal possession is treated.
Where to Buy Marijuana
Friendly Brazilian smokers were my best bet. Beach vendors and hippies selling jewelry sometimes knew somebody. For a better evening, there was Santa Teresa or Lapa.
People described weed turning up in streets and vielas in favelas, even while warning it wasn’t a safe place to buy or smoke. A traveler who’d already been in Brazil a while was easier to ask.
Marijuana Prices
The quotes were US$0.50 for poor favela weed, US$4 for mid-grade and US$15 for rare good stuff, without weights given. Another quote was R$2–5 per gram.
One exchange-rate note gave R$1 as US$2. That’s the figure quoted at the time, with no date to verify it.
Types of Marijuana
Mostly low-potency brick, “from brown to green, depending on how lucky you are.” Good weed was rare and dearer.
The best stuff I heard about came from Colombia or Paraguay, though Brazilian weed occasionally surprised me. Hash was plentiful.
