Based on my experiences with benzodiazapines (diazepam, tamazepam), there's definitely a feeling of "More of this would be _great_", even at very lose doses when I'm not really noticing it doing a lot else. With weak opioids (codeine, tramadol), I've never really noticed the same, even though they induce a far more noticeable high-like effect.
