Depends on how you unblock your chakras.
Both the addiction and the chakra energy blockages are symptoms of a deeper root cause: underlying beliefs or perspectives or fears causing the blockage and the addiction.
So if temporarily energy work is done to unblock the chakra, without actually changing the root cause belief, the addiction will remain, though there may be a temporary pause. If the beliefs change, thereby unblocking the chakra, then the addiction will indeed naturally fall away (unless the beliefs change back to the addiction-causing belief of course).
