Smoking weed and hip hop go together like Hall & Oates, Snoopy and Charlie Brown, and macaroni and cheese.
Along with the other main signifiers of the genre, which include a unique vernacular and dress code, getting high isn't so much a social necessity as a rite of passage.

There are traditionally two key factors that allow a particular album to be considered a great smoking album. First is the sound itself: laidback, mellow, trippy, and psychedelic sounds certainly help heighten the sensation of being high. For this, there are releases from every genre of music - be it classical, jazz, rock, house or world - and there are simply too many to mention (plus, it really depends on personal taste).
