"30 Days in the Hole" is a song by English rock band Humble Pie.

Released in late 1972, it was composed by the band's guitarist/singer Steve Marriott for the group's fifth album Smokin' (1972).

The song, a Steve Marriott composition, bemoans being arrested for possession of small quantities of illegal drugs, including cocaine; Durban poison, a potent strain of marijuana; and Red Lebanese and Black Nepalese, two types of hashish.

"[1] Marriott regularly played the song in the 1980s with his band Packet Of Three (with Jim Leverton and Jerry Shirley).

In the years since, "30 Days" has been recorded by several artists, most notably Gov't Mule, Mr. Big, Ace Frehley, The Black Crowes, Kick Axe, and The Dead Daisies, and is a live staple of Canadian rock band The Trews.
