Our researchers and interviewees perceived vein loss stemming from the injection of heroin alone to be a particular problem of BTH while among the Philadelphia sample, those who avoided the temptations of nearby cocaine sales displayed healthier injecting sites and reported few vein problems.
Abscesses were common across both sites, the Philadelphia sample generally blaming missing a vein when injecting cocaine and the San Francisco group finding several explanations, including the properties of BTH.

Street heroin is well known to vary in purity and adulterants Akhgari et al. Regional monopolies separate most US heroin consumers from the full range of heroin source-types sold in their country Ciccarone Since the s, consumers on the East Coast have been almost exclusively offered Naked vagina Bluff city Kansas powder heroin PH.
In the mids the sources of heroin shifted from four international regions to these two countries Ciccarone In the middle of the US, more competition exists between each source Rosenblum, Unick, and Ciccarone Strang et al first raised the ificance of these differences, specifically in relation to their comparative health risks in the United Kingdom.
In the US, Ciccarone and Bourgois hypothesized that injection preparation practices associated with these specific heroin source-types explain the higher prevalence of HIV among injection drug users IDUs in cities with PH market dominance relative to cities with BTH market dominance. In addition, BTH appears to induce venous scarring rapidly causing users to migrate to subcutaneous or intramuscular injection routes, with lower Younger guy seeking older mature woman transmission risks Bourgois and SchonbergRich et al.
Other public health risks have also been linked to particular source-types. BTH is also associated with specific infections: wound botulism Passaro et al. CiccaroneBinswanger et al.

A doubling in SSTI rates nationally between and was a particularly worrying finding. Adulteration by dealers could be seen as negative diluting or positive in the enhancement of the high and potency was not considered analogous with purity Bancroft and Scott Reid This study used ethnography and qualitative interviewing in Philadelphia and San Francisco. The ethnographic insertion of the same anthropological team in both cities provided privileged access to observational and interview data in the natural environment of street-based users and allowed comparative observations.
It informed the preparation of the interview guide and the recruitment priorities and sites for cross-regional comparison. For the qualitative interviews, the ethnographic work enabled a targeted sampling strategy, with purposive recruitment augmented by the snowball convenience sampling techniques generally used to Abandoned cars philadelphia hidden populations.
Interviewees over 18 who were current heroin injectors and living in either San Francisco or Philadelphia were recruited in What is black tar cut with of known open-air drug markets in both cities East haven vt free adult dating through needle exchanges. When it became clear that the effects of heroin on vein health was complicated by the injection of cocaine powder, we recruited additional users who injected only heroin.
All participants were interviewed once in and several were accompanied on multiple occasions. All the interviews were audio recorded and transcribed verbatim. Transcriptions were verified against the audio recordings for accuracy.
Twenty-two current heroin injectors were interviewed in Philadelphia and 19 in San Francisco. Details of the methods have been reported ly Rosenblum et al.

In San Francisco, BTH is a comparatively less refined substance which includes a mixture of alkaloids. It can require a knife to cut, be brittle enough to shatter or soft enough to stretch and tear apart when warmed to body temperature, perhaps in a pocket. Some speculated that it was cut with molasses, sugar, lactose or shoe polish but few had direct experience of the cutting process. Among many of the interviewees it had gained popularity as a higher potency alternative to the longer established product.
Some of the interviewees mentioned that it clumped together and became tar with small amounts of moisture, as when breathed on. Like tar, it needed heat to dissolve quickly but tended to be more soluble than BTH. A more refined powder heroin of widely varying purity was also reported on sale in San Francisco.

Only three of the Philadelphia sample used heroin but no cocaine at the time of the interview. However, others who had formerly injected only PH observed that they too Free older mature experienced few vein problems until they had added cocaine to San diego manscaping repertoire.
In their wider observations, the ethnographers witnessed no devastating vein loss among heroin injectors in Philadelphia except among those who also injected cocaine powder. Users in the Philadelphia group who had lost venous access Seeking Syracuse New York gordita often transitioned to injecting in their neck jugular vein but most drew the line at the groin femoral vein.
Some, like this 29 year old man, considered injecting into their neck particularly pleasurable:. It hits you a lot quicker, a lot more — it seems like it takes less and it just hits you better.

Seven had either never or only very rarely injected cocaine in the past or present. Most thought cocaine more destructive to their veins than BTH but some considered BTH equally damaging and several attributed the loss of many usable veins to black tar alone.
Some San Francisco users avoided intentionally muscling or skin popping BTH because, they said, it was painful or led to abscesses. The longer term use of more than one heroin source-type, enabling users to observe their comparative vascular effects was rare among the Philadelphia group, Hoover al craigslist one of whom had traveled extensively in her drug using career, sampling heroin across the US.
When asked to compare the different source-types, she was skeptical of differences between them aside from their injecting implications, saying:. People here want tar. I personally prefer China White honestly because the tar tears up your veins.
