A few mild scenes that are slightly sensual, such as characters grinding but are shown for a very short time. Partial nudity (eg; a teenage girl's bare back)

A girl searches through a boy's desk for his car keys and sees condoms. She makes a disgusted face and keeps looking. Played for laughs.

A brief sex scene between an older couple. Thrusting and moaning shown.

Two skinny dipping scenes.

One male rear nudity scene in a locker room.

A teenage boy kisses another teenage boy at a party.

40 f-words.

Book had no profanity, but this tv adaptation had f-words and profanity throughout. This would be enough to give it a more mature rating.

Lots of underage drinking amongst the characters, especially during party scenes.

The mothers are often shown smoking marijuana with each other and experiencing the effects.

Conrad is frequently shown smoking and drinking.

Underage drinking and frequent drug use throughout like it is normal behavior for teens. Parents encourage drug use and sex.
