Depends on how it affects. For Example if it changes something inside the body which causes the effect, it could be Transmutation only, if you want to affect them for a while, by binding your aura to them it could still be mainly transmutation since you don't need to extend it that far or that long. These two possibilities are both mainly transmutation since you don't extend it to far, but the main question is what causes the effect. Does your aura take on the properties  of Ethanol or even Methanol and it is then changed by the body into Etanal or Methanal, or does the Aura directly effect the brain thhrough its effect. Even if option two is the case I would still go for bigger effect rather than longer duration since even an Transmuter can propably with enought training maintain it over the duration of a fight.

Ps: If two is the case I would see it as necessary to hit the head for effect. To how the difficulty of Transmutating these is I would think option two is harder, since it is a mor abstract concept.(Its easier to learn by coming into touch with the object in question, than an abstract thing such as drunkenes, even if the person is drunk all the time)
