Abstract

BACKGROUND: Until about 2010, people who inject drugs (PWIDs) injected almost exclusively heroin and amphetamines in Hungary. After 2010, self-reported studies have indicated a dominance of new psychoactive substances on the drug market for injectable drugs.

METHODS: Between March 2015 and February 2016, we collected used and discarded injecting paraphernalia. We utilized chemical analysis to assess and UCINet to visualize the connections between the most prevalent main substances and their respective co-occurring additional components at 7 locations in Hungary.

RESULTS: The samples (n=2977) contained a mean of 4.5 components (SD=3.1, range: 1-18); 422 contained only one component. We found that the most common main components were the diverted substitution medication methadone (32%) and cathinones: pentedrone (18%), mephedrone (13%), alpha-PHP (8%), and alpha-PEP (5%). While these main substances also occurred among the top co-occurring additional components, caffeine and benzoic acid (a preservative) also frequently co-occurred.

CONCLUSION: A large number of co-occurring additional components indicate either common reuse of injecting paraphernalia or the common addition of additives or both. While caffeine may indeed be an adulterant, the high prevalence of benzoic acid may be difficult to explain. The preference of methadone despite the availability of a wide array of drugs may indicate a preference for opioids during the current heroin drought and/or a true demand for opioid substitution therapy.
