Labeling for opiates does not matter as opiates in and of themselves are highly unpredictable. Example: The same batch of heroin - first dose could be fine. You come back several hours later, take 1/3 the dose you did before and you're dead from an OD.

That's how a couple of people in my rehab ministry died. Meth is more reliably predictable in comparison.
