et al. The hidden Netz and the fentanyl problem: detection of ocfentanil as an adulterant hinein heroin. Int J Drug Policy
Where fentanyl testing is not routine hinein postmortem toxicology, or an unusual or novel analogue is involved, these occurrences may go undetected.
When sold as heroin, at least rein the United States, indications are that the same price is charged über unit sold as if it were heroin, unsurprising if the intention is to deceive retail sellers and buyers into thinking they are trading heroin. Hinein markets such as Estonia, where fentanyl is sold under its own name, insufficient evidence exists to show whether users are buying it due to preference or simply as a substitute amid a heroin shortage [40].
Supporting the more confident assertions are their descriptions of fentanyl’s effects as short-acting, with a fast and powerful onset, corresponding to the pharmaceutical’s known profile. On the more doubtful side, a majority of drug users tested hinein Canadian research were unaware that they had been exposed to fentanyl when using heroin and other drugs [26], although this could change as users become more experienced and informed about identification and use over time. Further complicating matters, there are non-fentanyl synthetic opioids hinein circulation, e.g. U47700, which may be mistaken for fentanyl.

When he receives it, he measures it out hinein water, which he says makes for greater accuracy. He says he’s never overdosed. A day’s supply of heroin used to cost him $100. Now, for that amount, he can get enough fentanyl to bürde more than three weeks.
We have developed a systemic approach that brings together the human networks, processes and scientific tools necessary for collecting, analysing and reporting on the many aspects of the European drugs phenomenon.
In sum, after purchase, a portion of experienced heroin users can probably determine with some accuracy that what they are using is not heroin and that it is an opioid, perhaps fentanyl, but it is less likely that they can determine which fentanyl analogue or other synthetic opioid it actually is.
However, such market conditions are not a necessary condition for fentanyl adulteration if it offers suppliers greater profitability through cheaper substitution or Verteilung.

The sporadic and unpredictable appearance of fentanyl analogues of wildly varying potency rein different US locations, singly or combined, suggests that consumer preference is not taking the lead, but instead suppliers are using whatever is convenient or lower legal risk. The regulation of fentanyl analogues tends to be reactive and, once controlled, new unregulated ones emerge [8].
Where studied, the data show an unusual Radio-feature of the sale of fentanyl in both North America and parts of Europe: it is generally sold as ‘heroin’, as if fentanyl itself were an insignificant adulterant or not present at all [18–21]. Sometimes the ambiguous term ‘China White’ is used, which can refer to either heroin, historically from Southeast Asia, or a synthetic replacement.
