The emergence of an illegal synthetic drug known as 'N-Bomb' or 'synthetic LSD' has seen five people treated in Christchurch Hospital's emergency department this week and left another in critical condition in ICU.
Canterbury Police and Canterbury District Health Board (CDHB) are concerned at the emergence of 25B-NBOMe, described as a powerful synthetic hallucinogen by the hospital's emergency medicine specialist, Dr Paul Gee.
"It is related to amphetamines so can cause toxicity associated with both classes of drug.
"Hallucinations , confusion and agitation are common symptoms, sometimes leading to uncontrollable violent behaviour."
NBOMe is sold as a white powder or in capsules. There have been deaths associated with NBOMe in Australia and in Asia.
