What King Vultan said is right on. I just also wanted to point out the fact that 2D6 is unique in that it is *uninducible*. No known drugs or foods speed up its processes -- certainly not the case for 1A2, 2C19, 3A4, and the rest.
Also, about inhibitors of 2D6 causing reduced efficacy of some drugs, this *does* happen in a few cases. Codeine, hydrocodone, oxycodone, and tramadol, for example, will not be (as) effective when administered with a 2D6-inhibitor. They all rely on this enzyme to convert to their prodrug forms -- morphine, hydromorphone, oxymorphone, and o-desmethyltramadol respectively.
