That's a nice variation of Nozick's experience machine [1] :). I wouldn't consider taking such a drug, because it leads attachment to that good mood. Attachment leads to unhappiness: that state may not be maintainable (shortage of drugs, rebirth if you believe in that, etc.) and we can always wish for more or better. I think that the highest form of happiness is non-attachment, being aware but not under control of pleasant and unpleasant experiences (akin to enlightenment in Buddhism).
