Just like the other Home Alones there's slapstick violence:

A man gets a bunch of large beeds shot at him from a machine.

A woman has black liquid dumped on her head.

A man has a white liquidy substance thrown onto him.

A woman is hit in the face with a filled stocking.

Policemen slip and fall on top of each other.

Some other action and slapstick violence is in the movie but it's meant for laughs.

1 use of hell and damn 2 uses of crap and sucks

The only thing is eggnog, also referred to in the film as 'adult eggnog'. There's no drug references (Besides the Eggnog and caffine) and I don't recall a single person smoking.

None

The main kid in the film is afraid of the haunted house and is scared of ghosts. No ghosts appear in the film.
