Just my perspective. Seeking alone implies lack, for we only seek when we don't feel like having "it" already.

As to alcohol, for me it is quite difficult to believe that someone really drinks it for the taste. Sure, we all perceive things different with our senses, but personally I don't like the taste at all. Not to even speak of the noxious effects. I almost only drink water, yet should I ever choose something else it will never be alcohol. Same applies to all those other addictions.
