I know at least one person who joined a commune there and said it was part of every day life. Plus, just look it up. Drugs are "cheap and plentiful" there
You know where drugs are cheap and plentiful? The US, Europe, London, Russia, Africa, basically everywhere. To say "Be aware drug trafficking is part of the culture there." is extremely weird and probably racist. Why are you saying that? If you think, "Oh it's central America" is that it? Costa Rica is actually not in any of the traditional drug trafficking routes (say from Peru to the US) so that line of thought just doesn't go anywhere. I've spent a lot of time in Costa Rica and I've never trafficked any drugs nor have I witnessed this cultural drug trafficking.
I imagine there is some sort of drug trafficking fiesta or holiday that I'm just constantly missing.
Clarified in another comment, what I should have said is it's decriminalized, and therefore may have a different culture around recreational use that may or may not suit everyone.
