Not terribly explicit. Rape and sex between minors are both implied or talked about at times. Sexual violence is certainly a topic the show deals with in some detail.

Brief but bloody violence - especially in the second season. There are shootings, dismemberment, drownings, etc.

F**k is said at least once per episode.

Our Lord's Name is abused a handful of times per season. Plenty of lower-tier obscenities, including sh** and the f-word.

Drugs is a major thematic ingredient. Although portrayed negatively, sometimes the use of drugs is shown explicitly.
