There are a couple scenes in which people make out and sex is implied; a woman is impregnated after one such scene.

No nudity.

A woman gives a man a blowjob off-screen.

A woman wears a white T-shirt, which gets wet in one scene; her breasts are somewhat visible.

Several people are killed by spear or knife, though none are very bloody.

A man is eaten by zombies, not very graphic.

A couple cannibalistic rituals are shown, and blood is shown in the first one.

I don't remember profanity very well but a few swear words were used.

People snort cocaine in several scenes.

A man smokes a joint in one scene.

People drink in one or two scenes.

The scenes in which people are killed may be scary for some viewers, though it is very low-budget so it is unlikely to scare many people.
