Iñárritu may not be Quentin Tarantino, but he gets pretty close with all the profanity thrown around. There's not a whole lot in terms of violence—unless two half-naked middle aged men rolling around makes you squeamish. Riggan does shoot his nose off, but we only have to see the after effects of the procedure. Drugs are mostly absent with the exception of a small joint that Riggan smokes briefly, and the drinking is mostly benign, until Riggan has a bit too much and falls asleep on the street.
There's nothing too graphic in terms of sex, other than a lingering shot of Mike's naked backside as he gets fitted, and Mike's erection through his pajamas, though. But these might not be images you want floating around in your mind.
