Ok well all that is great....but maybe someone can answer my question?
Since people on methadone/Bup will sometimes fall off the wagon, let's find a test to easily determine heroin's potency, b/c those on 'done/Bup, might think they're not getting high due to tolerance when in fact it may be due to the blocking effects of the drugs mentioned above, and that could be dangerous. (I.e.: someone uses triple normal dose to get high, then drugs wear off, and BAM--overdose). So if one can determine the strength of heroin with an easy test, they'd be able to know if it was a blocking problem, tolerance, or weak product.
Any input welcomed, thanks
