I'd also add there's the complicating factor of tolerance depending on the agent used (even if it took effect fast enough). Opiates would be a good choice (due to being relatively easily reversible by naloxone), but obviously would have diminished/unpredictable effects on a heavy opiate user. Likewise, benzodiazepines can have a huge range of active doses - a few hundred milligrams of, say, Temazepam could be bad news for a non-user (especially if they've been drinking), but I'm aware of people who have been awake and active despite having double that in their system.
