If Δ9-THC has effects on core brain reward circuits that are fundamentally similar to cocaine and heroin, why is Marijuana said to be "non habit-forming?"

"Non-habit forming" is really bad terminology.  A better terminology would be "not physiologically addictive."  The euphoric qualities of marijuana can certainly make people seek it out more, and this can turn into a habitual behavior.  But ultimately marijuana (unlike many other drugs) doesn't create a neurological situation where its continued presence is needed to avoid discomfort, sickness, or other negative effects.  The only negative effect of being a long-term marijuana user who is suddenly deprived of marijuana is that you don't have something in your life that you enjoy, much like being a football fan who suddenly can't watch the game.
