When you're high, where you are depends on the drug. They don't all cause the same incapacitating euphoria that fentanyl zombies experience. Alcoholics famously have a problem with driving while intoxicated, which is to say there's a state between sober and being blacked out. Some alcoholics just like a pleasant buzz and don't get to a point of euphoria and nothing else. Of course, cocaine addicts hash together elaborate business schemes while high to (to your point of stimulants being a gogogo drug), but then they're not in blissed out euphoria either, but actively thinking and planning and doing.
