This is a song about smoking weed I think. The double bubble reference goes two ways, cheech and chong obviously and then also a bong (double bubble). Usually "hits" are used when referring to smoking weed (although she could be smoking heroin), but the dry mouth thing has me believing it's weed. I've never really heard of junkies having cottonmouth. Lastly, I think the Junkie heart comment is just a sentimental reference to being a junkie at HEART and not necessarily in person.
