Public Health Sudbury and Districts is warning of the presence of a new potent substance in its region.
The health unit says the Community Drug Strategy's received confirmation of flubromazolam, a potent designer "benzo" also known as "liquid Xanax", warning it "can result in strong sedation and partial amnesia lasting more than 24 hours" or even death, "if taken in large quantities".
It further warns that taking benzos and opioids together increases the risk of poisoning - overdose - and death, recommending avoiding mixing drugs or alcohol, to carry a naloxone kit, not using drugs when you're alone - but also not at the same time as an accompanying friend - and - in the case of a suspected overdose - call 9-1-1.
