I've been following related research with interest and concern ever since I first heard of it. If these techniques are used to allow addicts who wish to conquer their addictions to do so, that is a very good thing. If they become used an in involuntary fashion ("Vaccinate your child against the effects of dangerous drugs!") it would be morally reprehensible. Voluntary alteration of consciousness with chemicals is a freedom that society should preserve. Involuntary vaccination against recreational drugs is not very different from involuntary brain surgery to prevent forbidden thoughts.
