Abstract:Introduction and Aims. Acetyl fentanyl, a fentanyl analogue emerging onto the recreational drug scene, has been responsible for numerous recent fatal overdoses in the USA, Europe and Russia. Studies reporting acetyl fentanyl use are presently limited to case studies and mortality reports. This study explores the nature of acetyl fentanyl use through the collection of first-hand qualitative data from users to inform public health and drug control policy responses. Design and Methods. A series of focus group int… Show more
“…We do not know if these are experimental one-time users or recurrent fentanyl users, nor do we know the reasons why respondents sought fentanyl. However, existing studies and anecdotal reports indicate that fentanyl enables a different drug experience than heroin (Miller, Stogner, Miller, & Blough, 2017). In their qualitative study of persons using heroin in Massachusetts and New Hampshire, Ciccarone and colleagues (2017) found that fentanyl’s intensity and potent ability to surpass heroin tolerance or OAT medicine was appealing to some people.…”
Nearly nine in ten participants tested positive for fentanyl, including participants who anticipated their tests would be negative. Leveraging toxicology results in opioid withdrawal settings may be helpful in educating patients about fentanyl exposure and risks.

“…Scientific literature reported a mixture of p-fluorofentanyl, alphamethylfentanyl, 3-methylfentanyl, acetyl-fentanyl which may include heroin constituents. [11][12][13][14] The danger related to fentanyl derivatives is due to: 1) the variability of compounds that may exist in a given sample 2) the inconsistency of dosages 3) their potency 4) easy access by consumers through the deep web or black market 14,15 and 5) fatal respiratory depression. In recent years, the great spread of fentanyl-like compounds has created massive problems from social, health, normative and analytical points of view.…”
Synthetic opioids, such as fentanyl and its analogues, are a new public health warning. Clandestine laboratories produce drug analogues at a faster rate than these compounds can be controlled or scheduled by drug agencies. Detection requires specific testing and clinicians may be confronted with a sequence of severe issues concerning the diagnosis and management of these contemporary opioid overdoses. This paper deals with methods for biological sample treatment, as well as the methodologies of analysis that have been reported, in the last decade, in the field of fentanyl-like compounds. From this analysis, it emerges that the gold standard for the identification and quantification of 4-anilinopiperidines is LC-MS/MS, coupled with liquid-liquid or solid-phase extraction. In the end, the return to the scene of illicit fentanyls can be considered as a critical problem that can be tackled only with a global multidisciplinary approach.
“…However, increasing variability in the evolving supply means that some individuals may be unable to discern fentanyl-adulteration (Amlani et al, 2015; Kenney et al, 2018). Research suggests that the fentanyl-adulteration does result in different intoxication effects in comparison heroin, including: intensity of onset, duration of action, increased overdose risk, and other embodied effects (Carroll et al, 2017; Ciccarone, 2017; Ciccarone et al, 2017; Macmadu et al, 2017; Mars et al, 2018; Miller et al, 2017; Somerville, 2017). As a result, fentanyl-adulteration has implications for overdose response in terms of rapid progression, and atypical physical symptoms (Somerville, 2017).…”
Background:
North America is experiencing an opioid overdose epidemic, fuelled by the proliferation of fentanyl, related analogues, and fentanyl-adulterated opioids. British Columbia, Canada has similarly experienced a rapid increase in the proportion of opioid overdose deaths associated with fentanyl. This study builds off of research characterizing fentanyl exposure to further explore the presentation of fentanyl use and related overdoses among people who use drugs.
Methods:
From December 2016 to April 2017, rapid ethnographic fieldwork was conducted in Vancouver, Canada to examine the implementation of low-threshold overdose prevention sites, where people use drugs under the supervision of staff and peers trained to respond to overdose. Data collection included 185 hours of ethnographic observation and in-depth interviews with 72 people who inject drugs, 44 of whom reported experiencing an overdose in the year prior to the interviews.
Results:
While most participants had experienced previous opioid-related overdose, they characterized how fentanyl was markedly distinct in terms of: potency, and rapid onset. Ethnographic observations and participant narratives highlighted how fentanyl use and related overdoses had implications for frontline response, including: rapid onset, multiple concurrent overdoses, body and chest rigidity, and the need to administer larger doses of naloxone.
Conclusions:
Participant narratives, and observational data documented distinct symptoms for fentanyl-attributed overdoses compared to other opioid related overdose events, which had implications for response. Findings may serve to inform best practices in responding to fentanyl-related overdoses including; the provision of oxygen and effective doses of naloxone, and also considerations regarding overdose identification.
