They are small, silver, metallic and cylindrical - and increasingly can be found almost anywhere.
But their innocent appearance belies the potentially dangerous contents, and their ubiquity has prompted concern amongst law-enforcers. Police said that, although the canisters had been spotted for some years, they have witnessed a recent increase in their number across Swansea and Neath Port Talbot, particularly in areas where young people are known to meet and congregate.
Before use, they contain nitrous oxide, more commonly known as laughing gas, but also referred to as whippits, chargers, hippy crack, balloons, noz or nos, and people use them to feel a 'high'. Officers have reported them becoming a common site for officers patrolling parks and open spaces, prompting a warning from South Wales Police for parents to be vigilant for signs children might be purchasing the substance online.
Chief Inspector Gareth Prosser said: “The apparent rise in the use of nitrous oxide is worrying, particularly with young people now spending increasing amounts of time together following the easing of lockdown restrictions. People may believe that because this gas is widely available and easily purchased, that it is harmless.
"However, inhaling nitrous oxide can be dangerous and can lead to loss of blood pressure, heart attack, unconsciousness and can ultimately lead to death".
There are a host of risks associated with inhaling nitrous oxide, including dizziness, while heavy regular use can lead to a deficiency of vitamin B12 and to a form of anaemia. Severe B12 deficiency can lead to serious nerve damage, causing tingling and numbness in the fingers and toes, which can become very painful and make walking difficult.
Regular use can also stop white blood cells forming properly. It can also be hard to judge the amount to use safely, leading to the risk of fainting, or becoming susceptible to having an accident. They can also lead to death.

Inspector Prosser added: “I’m asking our young people to really think about their actions and the possible consequences it could have. Please ask yourself if the risk of inhaling this substance is really worth the few seconds of feeling high? I’m also asking parents to be vigilant for the signs of nitrous oxide and speak to their young people about the risks associated with it.
"As mentioned, the gas is sold in small silver canisters and is usually inhaled through a balloon. So if you have seen paraphernalia in your home which matches these descriptions, please have a conversation and ensure your child is safe"
Anyone witnessing activity suspected to involve nitrous oxide is urged to report it to police on 101 so officers can visit the area.
