I have an old thread somewhere explaining why it's heroin. But I've come to accept the Devo part as well. Pretty simple really, the actual substance of the song is about heroin, it's dedicated and about his son because his son is what caused him and gave him the reason/relization that he couldn't go down the path of a junky rockstar. Being a heroin addict, no one could ever convince me different, even Maynard himself, even if he didn't intend it, it's hits me too perfectly to mean anything but heroin.
