The acute shortage has created widespread disorder among Canberra's drug-using community and raised fears by health workers about the impact on the already poor health of many addicted heroin users. They fear outbreaks of violence as dealers battle each other over scarce supplies, and supplies of cheap cocaine arriving on Canberra's streets at half the price of heroin. The head of ACT police operations, Commander Ben McDevitt, warned yesterday that the purity of street heroin had decreased dramatically in recent months and led to other drugs gaining favour. "We are seeing heroin being mixed with other drugs such as amphetamines," Mr McDevitt said. "Information from the street indicates the drug is scarce and in most cases non-existent. The impurity of the product has increased and local heroin has been cut or substituted with substances such as Gravox and gyprock." There was a clear message to illicit drug users to be aware because they did not know what they were injecting. Heroin supplies had been in decline for about two months and prices had increased threefold. The cost of an ounce of heroin had increased from between $4000 and $6000 in December to between $8000 and $15,000. Civil unrest and seasonal growing conditions in cultivating countries were factors. Another was Australia becoming a tougher target to penetrate. Huge national seizures showed it is more difficult to import drugs into Australia and this was having a dramatic impact on supplies. - ---
