If you have a decent income, it is possible to live with a oxycodone addiction. You know that the substance is free of adulterants and is consistently dosed. Pure oxycodone should have limited side effects.
However, if you are not in such a good financial position, a heroin addiction will almost certainly ruin your life. From the financial burden of the substance itself, to side effects from adulterants and the impredictability of a dose, you roll the dice every time you shoot up.
I'm not convinced that heroin ruins your life only because the dose is unpredictable. There's much more to it than that. Lets not pretend a heroin addiction could be a safe and normal way to live.
