Some kissing

A man gets a cut on his hand. It happens in a dark shot, but we can see blood and can't really figure out what has been cut especifically

Throughout the film there are many insults, that is the atmosphere of the place the main characters are and their socio-economic context.

There is some smoking throughout the film. In few scenes some of the protagonists are seen smoking what seems to be marihuana, but not specified or not really noticeable

A comment on soft drug (marihuanna). At the end of the movie, as a rhyme joke, a character says "Y como dijo Juana, a fumar marihuana" ("As Juana said, let's smoke marihuanna")
