Being in control doesn't negate altered judgement. Putting on a uniform and listing for a flight at sea level doesn't mean at a different time and a different cabin pressure altitude, he didn't experience different signs or symptoms.
There's nothing to imply premeditation here. His crime was taking the drug into his system in the first place and picking up an end of the stick . Pick up one end, own the consequences for the entire stick. By taking the drugs, he picked up one end, thus picked up the other, and owned the consequences that came as a result of taking the drugs in the first place. He may well have not been fully aware of his actions or the implications, or may have indeed thought he was dreaming, but that's still a consequence of his act of taking the drug. He owns the whole enchilada.
