YOUNG people are being warned about the dangers of inhaling ‘laughing gas’ following a sharp increase in the number of empty canisters being found across Swindon.

Also known as ‘hippy crack’, nitrous oxide is a legal way for people to get high and is on the increase.

It is often sold in small canisters which have been found littering parks, especially across North Swindon. In May, more than 70 were found at Moulden Hill.

Wiltshire Police say while it is unable to pin down exactly who is taking the substance, it is most likely to be youngsters. Officers also stressed that while it is not as dangerous as other drugs, there are substantial risks.

PCSO Emma Harriman said: “About a year ago this was not something which was a concern to us but over the last year we have been finding more of the empty canisters.

“There have also been more reports from members of the public, who are understandably concerned.

“We go into the schools to talk about the dangers of drugs and this term was the first we have had to raise the issue.

“I have to say, we were surprised by just how many knew exactly what we were talking about. With the summer holidays starting we have increased our patrols in parks and we are finding more and more.”

As well as being concerned about what could happen to someone while they are under the influence of laughing gas, PCSO Harriman is also worried at how people are taking the gas.

The gas is often taken through a balloon as if it is inhaled there is a small chance of getting frost bite on the face or suffocating due to the pressure.

But officers are not finding balloons with the canisters.

PCSO Harriman said: “There is a small percentage of this but it is a risk so we would ask parents to speak with their children about the dangers.”

This week, Lambeth Council in London became the first in the country to make it illegal to consume the substance in public.

Swindon Borough Council has said there are currently no plans to bring in similar laws here but if the problem grows it has not been ruled out.

Leader David Renard (Con, Haydon Wick) said: “We are not looking at introducing any laws at the moment but if it continues to be an issue we will monitor Lambeth to see how it works out.

“The health of residents is obviously important but we need to look at things properly and not make a kneejerk reaction.”
