I've only been trying to respond to this statement above, which wasn't yours >The exact same 'homogenized' batch can kill you at any time. One dose you can slam half a syringe, next dose a day or two later, you can do 1/4 that amount and die. Based on your elaboration, I suspect you agree with me that it is nonsense, and that opioids are far more predictible than it implies. Still, I believe you are overstating the danger associated with opioid dosing. This subjective tolerance you speak of likely falls within a reasonable narrow normal distribution and is the reason that based on your weight and gender, doctors may estimate a safe effective dose without titration. Also, I don't believe morphine injections are titrated.
