Does a man's divorce of his wife four separate times—one while intoxicated and three while consuming hallucinogenic pills—count, given his lack of awareness of his actions during those states, and is it permissible for him for him to take her back?

Taking drugs and intoxicants is a grave evil and a major sin that incurs Allah's wrath. The ruling on the divorce of an intoxicated person differs; the preponderant view is that if he has lost consciousness, his divorce is not effective. However, if he is aware of what he is saying, then his divorce is effective. It is necessary to refer the matter to the Sharia court for the judge to consider.
