Empty canisters containing a substance known as ‘Hippy Crack’ have been found by police at Abergavenny’s Bailey Park.

The used silver bullet-shaped capsules which usually contain Nitrous Oxide were discovered on New Year’s Eve, by a local Police community support officer, sparking fears that locals are using the canisters for their drug-like effects.

Abergavenny PCSO Amanda Yung, said, “It is something we see from time to time with no real pattern to where or when they appear. 

“We’re really looking to educate members of the public on the dangers, so they can pass on the information to others.”

The Chronicle reported last year on the growing evidence of use of the canisters in Bailey Park after a large number of used canisters were found.

Police have said recreational use of the drug is on the rise, with users reporting a brief but intense high that leaves them feeling euphoric, relaxed and giggly.

Users often fill balloons with the gas and inhale deeply, causing a short-lived high which can cause significant risks to the respiratory system, in some cases leading to death.

Drug treatment groups have said people have reported suffering from seizures, falls and breathing problems after inhaling the drug.

The anaesthetic is still used for pain relief during dentistry and childbirth, but has been a topic of concern recently as governments seek to stem the growth of so-called legal highs.

According to the drugs advice website, Talk to Frank, Nitrous oxide is a gas with several legitimate uses, including to numb pain during medical procedures, and in the catering industry.

It is currently illegal to sell to under-18s, but the gas is legitimately sold as a ‘whipped cream charger’ usually employed by caterers, and could be easier to purchase than alcohol.
