The movie, like the book, has important messages about the purpose of life: what it means to make your mark in the world and to be loved and remembered, how love can feel infinite even in a finite number of days, and how what afflicts you isn't what defines you. Most of the messages are about life, love, and relationships -- as well as literature and what it means to feel connected to the books we read. Gus' motto that you can't keep yourself from getting hurt -- but you can choose wisely about who you allow to hurt you -- is a powerful one.
The way that cancer physically and emotionally affects the teen characters is likely to disturb and upset viewers. A key character's death devastates other characters (as well as the audience). Characters egg another character's car.
There's one love scene, and it's more emotional than physical in its depiction and doesn't feel gratuitous. It takes place between two teens who are both virgins, and this is their one and only time making love. The girl has her top off, but you just see her back and the boy's chest. Afterward they're shown sleeping in each other's arms. Also a few passionate kisses.
One use of "f--k," plus a couple of uses of "s--tty," "a--hole," "douchepants," and "goddamn."

Drinking, Drugs & Smoking
Gus has a habit of putting an unlit cigarette in his mouth and letting it dangle there, since unlit it can do no harm (he says it's a metaphor). He goes around with the same cigarette pack for most of the movie. Gus and Hazel drink champagne together twice. Author Peter Van Houten is a drunk and is nearly always shown with a drink or a flask in his hand. Hazel teases her parents that she should be allowed to be a regular teen with a fake ID so she can drink and "take" pot.
