Couples are seen but they are covered up with no nudity and nothing happens.

Clothes are torn off due to the vampires' superhuman strength. Nudity is only implied.

Two vampires make out including tearing of a shirt and a dress and lots of slamming each other against walls at vampire speed. Neither one of them is hurt by this. There is no nudity and the scene is mild and brief. The detail shown is very brief. It is blurry because of the vampires super speed and a short scene.

Uses of the words ass, bitch, bastard, damn, hell, dick and other mild words.

Quite strong but infrequent drug use in the first few series, but it dies down almost completely by later seasons.

One boy is a drug dealer and abuser and would be no older than 15/16 years old and he is shown getting high. But it's not too inappropriate or detailed and the scenes are brief.

Lots of drinking, mostly from underage teenagers.

One of the main characters drinks almost every episode and due to being a vampire his tolerance for alcohol is very high so it takes quite a but of drinking to get him drunk. This is more humorous and ironic than it is inappropriate or intense.

In season 6 a female vampire uses a hallucinogenic magic drug which allows her to see her dead boyfriend whilst under its influence and is seen using it quite a few times, but it is not inappropriate and is obviously supernatural.

The entire series features shocking and frightening scenes due to the supernatural elements that are vampires and other supernatural beings.

Many torture scenes are featured.
