A “significantly dangerous substance” linked to at least one sudden death on the northeast Avalon is circulating in the community, and Naloxone does not counter its effects.

The substance in question is Bromazolam, (a benzodiazepine) and it’s such a concern for law enforcement, RNC issued a warning to the public this week.

Health Canada confirmed the presence of the substance, which was being passed off as Xanax. Bromazolam is not approved for medical use in any country and can result in serious adverse effects, including death.

The greatest concern, says RNC Constable James Cadigan, is when the drug, also known as benzos, are used with opioids, a practice known as a benzo-dope.

He says Naloxone, which is used to counteract the effects of opioids, has no effect if a person is suffering an overdose from benzodiazepines.

And that’s why law enforcement is trying to get the message out says Cadigan. For those who use illicit drugs, it’s important to check the strength by starting with small amounts and pace yourself. Never use alone, and if you are going to use alone, keep your door unlocked and ask someone you trust to check on you.

The bottom line says Cadigan, is that it’s difficult to know for certain what you’re getting on the illicit market.
