Addicted to a particular pleasure even when you know it has its drawbacks. There’s a passage where the Buddha says that the reason we get so stuck on sensual desires, sensual pleasures, is because we don’t see any other alternative to pain. But when you see that there is the alternative and, as you reflect on it, you see that it has fewer drawbacks, greater rewards, and that you can learn how to tap into it when you need it, then it can be your new attachment—a better one. Does anyone know in which sutta that this passage is found?  Could someone help me in this?
Even after one has seen and understood that there's a better way, that's still not sufficient to abandon sensual pleasures. One would need to attain and experience the higher path himself. As taught in MN 14:


  Even though a disciple of the noble ones has clearly seen as it actually is with right discernment that sensuality is of much stress, much despair, &amp; greater drawbacks, still — if he has not attained a rapture &amp; pleasure apart from sensuality, apart from unskillful mental qualities, or something more peaceful than that[4] — he can be tempted by sensuality. But when he has clearly seen as it actually is with right discernment that sensuality is of much stress, much despair, &amp; greater drawbacks, and he has attained a rapture &amp; pleasure apart from sensuality, apart from unskillful mental qualities, or something more peaceful than that, he cannot be tempted by sensuality.
