The father of a 20-year-old man on life support after taking an illegal synthetic drug has described his shock at discovering his son was dabbling in drugs.
Canterbury dad Murray, who did not wish to use his last name, said in statement today that he was still lost for words after the shocking news his son Michael had been hospitalised in a critical condition.
Michael was brought to Christchurch Hospital on Wednesday suffering an adverse reaction to a drug known as 'N-Bomb'.
He was among five people hospitalised that day after taking 25B-NBOMe, also known as synthetic LSD - a powerful synthetic hallucinogen related to amphetamines, which can cause toxicity associated with both classes of drug.
Michael is in the worst condition, suffering multiple organ failure and requiring life support in the intensive care unit where he has been since his admission.
His father said he was unaware Michael had been dabbling in recreational drug use.
"I've had a couple of shocks over the past week. I thought Michael had been going to uni - but he hasn't."
Murray said he and the rest of the family were still trying to come to grips with the events leading up to Michael's admission.
"I have never seen so many young boys crying. It's been a hell of a shock. I didn't even know this stuff existed before last week," Murray said.
"The other thing I'm quite shocked about is just how prolific the use of cannabis as well as all this synthetic stuff is. I'm also concerned about how many young people know where to get it and how cheap it is."
Murray said it was difficult to give other parents advice on how to avoid this happening.
"Being a parent - it's all about trust. I guess, it's probably watching the peer group. But sometimes it's the people you least expect."
NBOMe is sold as a white powder or in capsules. Recreational doses are measured in tiny microgram quantities - less than the size of a match-head - so it is very easy to use too much.
Hallucinations, confusion and agitation are common symptoms, sometimes leading to uncontrollable violent behaviour. Use of the drug has been associated with deaths in Australia and Asia.
Police and health officials are warning people to avoid any drug that is sold as an NBOMe or an 'LSD-type drug' and seek medical help immediately for anyone suffering from adverse reactions.
Detective Senior Sergeant Jason Stewart said the last time there was a cluster of people requiring treatment after using synthetic drugs in Christchurch was around six months ago.
Police were working closely with Customs and other agencies nationwide to target users and distributors of these substances, as the effects of these drugs could be unpredictable and highly dangerous.
Investigations into the drug incidents were ongoing and police were keen to hear from anyone with any information that may assist.
