I dunno about the LSD part, but, in my experience, whenever I have a craving, I try to first (not always, and probably not most of the time) feel the feeling that I'm trying to avoid with the addiction.  Whatever it is.  And, depending on the severity of suffering in that feeling, I may just mindfully feel it for a few seconds and then do the addiction, or, sometimes, I'm able to fully be with it without letting the addictive behavior happen and then transcend and heal that suffering feeling by feeling it all the way through.  Usually something comes up when feeling these unwanted feelings, I think often pain of some sort.
