First of all, I've taken them, so I know anecdotally. Secondly, the bond strength is what makes them much more addictive. It's why Heroin is more addictive than Morphine. Why Fentanyl is more addictive than Heroin. And so on. Weaker drugs, one may need to take higher mg doses but tend to be less addictive.
