Older teenagers and adults have admitted to enjoying "Scooby-Doo" because of presumed subversive themes which involve theories of drug use and sexuality, in particular that Shaggy is assumed to be a user of cannabis and Velma is assumed to be a lesbian. Such themes were pervasive enough in popular culture to find their way into Warner Bros.' initial "Scooby-Doo" feature film in 2002, though several of the scenes were edited before release to secure a family-friendly "PG" rating. Series creators Joe Ruby and Ken Spears reported that they "took umbrage" to the inclusion of such themes in the "Scooby-Doo" feature and other places, and denied intending their characters to be drug users in any way.
