Recent incidents in Melbourne have highlighted a serious concern regarding the sale of heroin disguised as cocaine and methamphetamine. This alarming trend has resulted in two individuals requiring emergency medical attention due to overdoses, prompting Health Victoria to advise the community to be vigilant about potentially contaminated or fraudulent drugs.
Investigations into these cases suggest that the cocaine and methamphetamine consumed by the victims were mixed with heroin. Comprehensive blood tests revealed the presence of all three substances, indicating adulteration. The risks associated with such combinations are significant; even minuscule quantities of heroin can lead to fatal overdoses, especially in individuals with no prior exposure to opioids. The danger escalates further when these drugs are consumed alongside alcohol or other depressants like GHB and benzodiazepines (e.g., Xanax, Valium).
While cocaine and methamphetamine act as stimulants, heroin depresses the nervous system, which can produce erratic and unpredictable reactions in the body. Recognising the signs of an opioid overdose is critical; symptoms to look out for include shallow breathing, difficulty staying awake, or unresponsive behaviour, alongside constricted pupils.
Health authorities urge individuals who intend to use drugs to be especially cautious about adulteration, even when there are no specific alerts regarding the substances they are taking. Carrying naloxone, an opioid reversal medication, is recommended. Naloxone is accessible without a prescription in various forms, including nasal spray and injections, at certain pharmacies, needle exchange programs, and medically supervised injecting centres.
Health Victoria advises that even ‘pure’ substances pose significant risks, and the mantra of ‘start low and go slow’ should be adhered to for safety.
