"In sum, these observations suggest that the relatively limited availability of black market opiates and stimulants and the relative ease of harvesting legal precursors to powerful analogues from the countryside and pharmacies inspired and sustained a Soviet-style homemade drug culture in the Eastern European region that remains radically different from those observed in countries where narco-traffickers dominate the production and distribution of drugs (Booth, Kennedy, Brewster, & Semerik, 2003; Grund et al., 2009; Grund, 2005; Subata & Tsukanov, 1999; Zábransky, 2007).
"The physical and logistical exigencies of home production; its locus in networks of drug injecting friends and the high degree of cooperative action involved (in foraging for, producing and using the drugs); the multiple roles and ambiguous status of injecting paraphernalia; the routine occurrence of well-known risk behaviours (e.g. syringe sharing, frontloading) and those currently less well understood, such as the slapdash nature of the bootleg drug synthesis and its unpredictable outcomes in terms of actual drug product, purity and pollution— indeed all of these factors contribute to and interact within the vastly complex high risk environment of home drug production in the region."
