Alright mate i was there in October through to November for 3 weeks but previously worked there for 13 months between 2022 & 23.
Don’t go anywhere on your own would be my advice, Don’t go walking on your own and stay in well lit areas.
It’s a dangerous place for sure so keep your wits about you.
There’s been a resent spate of Alcohol getting poisoned with drugs. sorry i can’t remember the drug but it’s been rife recently especially in Rio & São Paulo.
If your having beer always drink bottles if possible it’s the only thing they can’t tamper with and i’m not talking about backstreet bars i’m talking hotels, nightclubs and so on. Draughtcis the easiest for them to tamper with but they can also do it with cans.
Watch the woman as well,
as you know some are very attractive and they’ll want to buy you drinks then the next thing your back in your hotel room they’ve slipped something in your beer & cleared you out this has happened regular to colleagues of mine.
You will have a great time it’s some place but just don’t get taken in.
