To answer your question, it is not a defene to a criminal charge that the victim was impaired. Self-defense is another matter. If you wish to recant whatever allegations you made while effectively unconscious due to the substance you had ingested, you can, which may or may not be considered by the prosecutor.
Your boyfriend should consult with qualified criminal defense counsel. And you should consider a course of counseling with someone experienced in drug and alcohol dependency, for his sake and your own, before something irreversible happens during one of those blackouts.
